VU#538470: Clevo UEFI firmware embedded BootGuard keys compromising Clevo’s implementation of BootGuard

VU#538470: Clevo UEFI firmware embedded BootGuard keys compromising Clevo’s implementation of BootGuard

Overview
Clevo’s UEFI firmware update packages included sensitive private keys used in their Intel Boot Guard implementation. This accidental exposure of the keys could be abused by an attacker to sign malicious firmware using Clevo’s Boot Guard trust chain, potentially compromising the pre-boot UEFI environment on systems where Clevo’s implementation has been adopted.
Description
Intel Boot Guard is a platform integrity technology, providing a root of trust that protects the earliest stages of the boot process. It cryptographically verifies the Initial Boot Block (IBB) and prevents the execution of untrusted firmware. Operating before UEFI is initialized, Boot Guard ensures that only authenticated firmware is executed during the earliest pre-boot stage. Boot Guard is often confused with UEFI Secure Boot, but Secure Boot operates later in the process, enforcing trust within the UEFI firmware execution phase and during the transition from UEFI to the operating system.
Clevo Co. is a computer hardware and firmware manufacturer that operates as both an Original Design Manufacturer (ODM) and an Original Equipment Manufacturer (OEM), producing laptops and UEFI firmware used by various personal computer brands. One of Clevo’s publicly released UEFI software executables included private keys integral to its Boot Guard trust chain. Because Clevo’s firmware is integrated into products from other manufacturers, the exposure may have supply chain implications extending beyond Clevo-branded systems.
Impact
An attacker with write access to flash storage for a system, whether through physical access or a privileged software update mechanism, could abuse the leaked keys to sign and install malicious firmware. Such firmware would be trusted at the early stages that will be protected by Boot Guard, allowing compromise of the affected UEFI systems and thus enabling persistent and stealthy control over the device.
Solution
While Clevo has reportedly removed the affected software containing the leaked keys, no public remediation steps have been announced by Clevo at this time.
Users of Clevo-based devices, including those from other OEMs that integrate Clevo firmware, should:
* Assess their exposure to affected firmware versions.
* Monitor systems for unauthorized firmware modifications.
* Apply firmware updates only from verified and trusted sources.

VU#887923: Kiwire Captive Portal contains 3 web vulnerabilities

Overview
The Kiwire Captive Portal, provided by SynchroWeb, is an internet access gateway intended for providing guests internet access where many users will want to connect. Three vulnerabilities were discovered within the product, including SQL injection, open redirection, and cross site scripting (XSS), allowing an attacker multiple vectors to compromise the device. All three of the vulnerabilities have been addressed by the vendor. Customers using the Kiwire Captive Portal are recommended to update to the latest version of the product to remediate the vulnerabilities.
Description
The Kiwire Captive Portal is a guest wifi solution that provides users with internet access through a login system. The product is used in various different capacities across different enterprises, including hotels, office systems, and other companies. Three vulnerabilities have been discovered within the product that allow an attacker to compromise the Kiwire Captive Portal database, redirect users to a malicious website, and trigger JavaScript upon visiting the captive portal with the malicious payload appended in the URL.
The following is a list of the CVE assignments and their respective vulnerability details:
CVE-2025-11188
The Kiwire Captive Portal contains a blind SQL injection in the nas-id parameter, allowing for SQL commands to be issued and to compromise the corresponding database.
CVE-2025-11190
The Kiwire Captive Portal contains an open redirection issue via the login-url parameter, allowing an attacker to redirect users to an attacker-controlled website.
CVE-2025-11189
The Kiwire Captive Portal contains a reflected cross-site scripting (XSS) vulnerability within the login-url parameter, allowing for JavaScript execution.
Impact
The vulnerabilities allow an attacker to exfiltrate sensitive data from the Kiwire Captive Portal database (CVE-2025-11188), redirect a user attempting to login to the captive portal to a malicious website (CVE-2025-11190), and execute JavaScript on the device that is attempting to login to the captive portal (CVE-2025-11189). It should be noted that in regards to CVE-2025-11189 and CVE-2025-11190, the domain is automatically trusted on most devices, due to it being a local address that users must access prior to being granted internet access.
Solution
A security advisory is available on the Kiwire website: https://www.synchroweb.com/release-notes/kiwire/security
SynchroWeb will be contacting individuals who use affected version to assist in their patching process.

VU#294418: Vigor routers running DrayOS are vulnerable to RCE via EasyVPN and LAN web administration interface

VU#294418: Vigor routers running DrayOS are vulnerable to RCE via EasyVPN and LAN web administration interface

Overview
A remote code execution (RCE) vulnerability, tracked as CVE-2025-10547, was discovered through the EasyVPN and LAN web administration interface of Vigor routers by Draytek. A script in the LAN web administration interface uses an unitialized variable, allowing an attacker to send specially crafted HTTP requests that cause memory corruption and potentially allow arbitrary code execution.
Description
Vigor routers are business-grade routers, designed for small to medium-sized businesses, made by Draytek. These routers provide routing, firewall, VPN, content-filtering, bandwidth management, LAN (local area network), and multi-WAN (wide area network) features. Draytek utilizes a proprietary firmware, DrayOS, on the Vigor router line. DrayOS features the EasyVPN and LAN Web Administrator tool s to facilitate LAN and VPN setup. According to the DrayTek website, “with EasyVPN, users no longer need to generate WireGuard keys, import OpenVPN configuration files, or upload certificates. Instead, VPN can be successfully established by simply entering the username and password or getting the OTP code by email.”
The LAN Web Administrator provides a browser-based user interface for router management. When a user interacts with the LAN Web Administration interface, the user interface elements trigger actions that generate HTTP requests to interact with the local server. This process contains an uninitialized variable. Due to the uninitialized variable, an unauthenticated attacker could perform memory corruption on the router via specially crafted HTTP requests to hijack execution or inject malicious payloads. If EasyVPN is enabled, the flaw could be remotely exploited through the VPN interface.
Impact
A remote, unathenticated attacker can exploit this vulnerability through accessing the LAN interface—or potentially the WAN interface—if EasyVPN is enabled or remote administration over the internet is activated. If a remote, unauthenticated attacker leverages this vulnerability, they can execute arbitrary code on the router (RCE) and gain full control of the device. A successful attack could result in a attacker gaining root access to a Vigor router to then install backdoors, reconfigure network settings, or block traffic. An attacker may also pivot for lateral movement via intercepting internal communications and bypassing VPNs.
Solution
The DrayTek Security team has developed a series of patches to remediate the vulnerability, and all users of Vigor routers should upgrade to the latest version ASAP. The patches can be found on the resources page of the DrayTek webpage, and the security advisory can be found within the about section of the DrayTek webpage. Consult either the CVE listing or the advisory page for a full list of affected products.

VU#534320: NPM supply chain compromise exposes challenges to securing the ecosystem from credential theft and self-propagation

VU#534320: NPM supply chain compromise exposes challenges to securing the ecosystem from credential theft and self-propagation

Overview
A major npm supply chain compromise was disclosed by the software supply chain security company Socket on September 15, 2025. At the time of writing, over 500 packages have been affected, and the number continues to grow. The attack involves a self-propagating malware variant dubbed Shai-Hulud, which spreads via credential theft and automated package publishing. The campaign escalated rapidly, including compromise of packages published by CrowdStrike.
This notice aims to raise awareness about growing risks in software development and packaging practices within the npm ecosystem that can lead to large-scale compromises. The incident highlights ongoing exploitation of known attack vectors, including credential theft, package impersonation, and automated propagation, all of which undermine the integrity of widely used package ecosystems like npm.
Description
npm is the default package manager for Node.js. It provides a global registry and command-line interface that helps developers install, manage, and share JavaScript packages and dependencies. It simplifies the integration of third-party code through the use of the package.json and package-lock.json files, which ensure dependency consistency and reproducibility.
The compromise likely began with a credential harvesting campaign, where a postinstall script led to the execution of a malicious bundle.js file. postinstall scripts are an npm feature that allow code execution following package installation. The bundle.js script scanned the target environment for exposed secrets in code and configuration files. The bundle.js file downloaded and used TruffleHog, typically used for legitimate secret scanning, to harvest credentials stored as environment variables or secrets used by continuous integration and continuous delivery (CI/CD) platforms such as GitHub Actions, GitLab CI, Jenkins, and others. The malware self-propagated using the stolen credentials to publish itself to other repositories and package registries, effectively turning compromised environments into new infection vectors.
A key mechanism of propagation was the automatic “trojanization” of CI/CD tools, a known attack vector with wide-reaching implications across ecosystems. GitHub Actions was one such capability that was abused, previously seen in attacks like the Nx package compromise in August of 2025. Another known contributor to the attack was the abuse of the postinstall script capability in npm. This technique has been exploited in previous incidents, such as the event-stream attack in 2018. These vulnerable software development and design methods in npm have been duly abused in this combined attack.
Impact
At the time of publication, over 500 packages have been confirmed to be compromised by the Shai-Hulud malware. Socket is maintaining a live list of affected packages on their website. Organizations using CrowdStrike products should also inspect their npm package dependencies, as the npm account used to manage and publish packages for CrowdStrike was allegedly compromised.
Solution
GitHub has released a public advisory detailing additional security changes being made to their package systems. CISA has also released a security advisory.
For npm Users

Audit and replace compromised packages: Remove any affected package versions and replace them with known safe versions.
Lock dependencies: Use package-lock.json or npm i –package-lock-only to lock resolved dependency versions without executing install scripts, allowing safe auditing. For packages that will be redistributed, locally or otherwise, use npm shrinkwrap to lock all direct and transitive dependency versions for reproducible installs.
Use internal mirrors: Set up an internal npm registry using tools like Verdaccio or Artifactory, and centrally approve packages before allowing internal use.
Disable postinstall scripts: Use npm install –ignore-scripts where feasible to prevent malicious code execution during package installation.

For npm Developers

Rotate all exposed credentials: Immediately revoke and rotate any CI/CD-related tokens or secrets (GitHub, GitLab, Jenkins, etc.) that may have been exposed.
Enforce least privilege: Use scoped tokens with minimal permissions, and isolate build environments to ensure untrusted code never has access to publishing credentials, especially when using GitHub Actions or similar CI/CD platforms.

VU#780141: Cross-site scripting vulnerability in Lectora course navigation

VU#780141: Cross-site scripting vulnerability in Lectora course navigation

Overview
Lectora Desktop versions 21.0–21.3 and Lectora Online versions 7.1.6 and older contained a cross-site scripting (XSS) vulnerability in courses published with Seamless Play Publish (SPP) enabled and Web Accessibility disabled. The vulnerability was initially patched in Lectora Desktop version 21.4 (October 25, 2022), but users must republish existing courses to apply the patch. This important republishing instruction was missing from the Desktop edition release notes, but it was included in the release notes for the recently patched Lectora Online (July 20, 2025). The CERT® Coordination Center is publishing this vulnerability note to amplify awareness as the Lectora software user base includes high-profile clients such as government agencies and large enterprises.
Description
The Lectora platform is used to create and publish interactive e-learning courses by ELB Learning. Lectora Inspire and Lectora Publisher are Desktop versions of the e-learning software, and Lectora Online is a cloud-based version.
Affected Versions

Lectora Inspire and Lectora Publisher desktop editions versions 21.0–21.3
Lectora Online versions 7.1.6 and older

Impact
Content published with Seamless Play Publish (SPP) enabled and Web Accessibility settings disabled in the affected versions can allow JavaScript injection via crafted URL parameters. Exploitation under this scenario could result in client-side script execution (e.g., alert or redirect), which poses a risk of session hijacking or user redirection.
Solution
The vulnerability is patched in Lectora Desktop (Publisher and Inspire version 21.4, released October 25, 2022) and Lectora Online (version 7.1.7, deployed July 20, 2025). To fully implement the solution:

For Lectora Desktop customers: Please download the version 21.4 patch or a later update from portal.elblearning.com. You must then republish any courses that were created using older software versions.
For Lectora Online customers: The update to version 7.1.7 was automatically applied on July 20, 2025. You must republish any courses that were created using older software versions.

VU#949137: Langchaingo supports jinja2 and gonja for syntax parsing, allowing for arbitrary file read

VU#949137: Langchaingo supports jinja2 and gonja for syntax parsing, allowing for arbitrary file read

Overview
LangChainGo, the Go implementation of LangChain, a large language model (LLM) application building framework, has been discovered to contain an arbitrary file read vulnerability. The vulnerability, tracked as CVE-2025-9556, allows for arbitrary file read through the Gonja template engine with Jinja2 syntax. Attackers can exploit this by injecting malicious prompt content to access sensitive files, leading to a server-side template injection (SSTI) attack.
Description
LangChainGo is the Go Programming Language port/fork of LangChain, an open-source orchestration framework for the development of applications that leverage LLMs. LangChainGo uses Gonja for syntax parsing and creating dynamic and reusable prompt templates. Gonja is the Go implementation of Jinja2, a templating engine. Gonja is largely compatable with the the original Python Jinja2 implementation, and supports Jinja2 syntax.
As Gonja supports Jinja2 syntax, an attacker could leverage directives such as % include %, % from %, or % extends % for malicious purposes within LangChainGo. While these directives were meant to be used for building reusable templates, they can also allow an external file to be pulled and read from the server’s filesystem. An attacker could use this to inject malicious template code containing advanced templating directives to read sensitive files such as /etc/password. This results in a server-side template injection vulnerability that can expose sensitive information. This vulnerability is tracked as CVE-2025-9556.
Impact
This vulnerability compromises the confidentiality of the system by enabling arbitrary file read on a server running LangChainGo. By injecting malicious template syntax, an attacker could access sensitive information stored on the victim device. This information can lead to further comprise of the system. In LLM-based chatbot environments that use LangChainGo, attackers would only need access to the prompt to maliciously craft and exploit the prompt.
Solution
The maintainer of LangChainGo has released with new security features to prevent template injection. A new RenderTemplateFS function has been added, which supports secure file template referencing, on top of blocking filesystem access by default. Users of LangChainGo should update to the latest version of the software in order to be protected.

VU#974249: Elevated Privileges and Arbitrary Code Execution issues in Sunshine for Windows v2025.122.141614

VU#974249: Elevated Privileges and Arbitrary Code Execution issues in Sunshine for Windows v2025.122.141614

Overview
Two local security vulnerabilities have been identified in Sunshine for Windows, version v2025.122.141614 (and likely prior versions). These issues could allow attackers to execute arbitrary code and escalate privileges on affected systems.
Description
Sunshine is a self-hosted game stream host for Moonlight.

CVE-2025-10198 Unquoted Service Path (CWE-428)
Sunshine for Windows installs a service with an unquoted service path. This allows an attacker with local access to place a malicious executable in a directory within the service path (before the legitimate binary), which could then be executed with elevated privileges during system startup or service restart.

CVE-2025-10199 DLL Search-Order Hijacking (CWE-427)
Sunshine for Windows does not properly control the search path for required DLLs. This allows an attacker to place a malicious DLL in a user-writable directory that is included in the PATH environment variable. When the application loads, it may inadvertently load the malicious DLL, resulting in arbitrary code execution.

Impact

CVE-2025-10198 Attackers with local access can escalate privileges to SYSTEM, resulting in full compromise of the affected machine.
CVE-2025-10199 Attackers can execute malicious code in the context of the user running the application.

Solution
Apply an update from the Sunshine project once available.
As mitigation, until a patch is released:

Ensure user-writable directories are not included in the PATH environment variable.

Quote all service paths in Windows service configurations.

Restrict permissions on service-related directories to prevent unauthorized file placement.

VU#763183: Amp’ed RF BT-AP 111 Bluetooth access point lacks an authentication mechanism

VU#763183: Amp’ed RF BT-AP 111 Bluetooth access point lacks an authentication mechanism

Overview
The Amp’ed RF BT-AP 111 Bluetooth Access Point exposes an HTTP-based administrative interface without authentication controls. This allows an unauthenticated remote attacker to gain full administrative access to the device.
Description
The Amp’ed RF BT-AP 111 is a Bluetooth-to-Ethernet bridge that can function as an access point or a Bluetooth gateway. According to the vendor’s website, the device supports Universal Plug and Play (UPnP) on the Ethernet side and acts as a UART Serial device to support up to seven simultaneous Bluetooth connections.
The BT-AP 111 provides a web-based administrative interface over HTTP. However, this interface does not implement any authentication mechanism. As a result, any user with network access to the device’s HTTP port can view and modify the administrative interface. An attacker with such access can alter Bluetooth configurations, network parameters, and other security-related settings.
According to NIST guidance, authentication is an expected baseline security control even for near-field or Bluetooth devices. The NIST Guide to Bluetooth Security (SP 800-121 Rev. 2), defines security levels that require at least authentication (Service Level 2) and preferably authentication and authorization (Service Level 1). More broadly, NIST SP 800-124 Rev. 1 emphasizes that devices should enforce authentication before granting access to configuration or administrative resources. The absence of authentication on the BT-AP 111 administrative web interface is therefore inconsistent with established best practices.
Impact
An attacker with network access (local or remote) to the web interface can gain full administrative control of the device and modify any settings exposed through the interface.
Solution
At this time, CERT/CC has not received a response from the vendor regarding this vulnerability. Since the device cannot be secured with authentication or any access controls, it is recommended that any deployments be restricted to isolated networks that are inaccessible to untrusted users.

VU#461364: Hiawatha open-source web server has multiple vulnerabilities

VU#461364: Hiawatha open-source web server has multiple vulnerabilities

Overview
Hiawatha is an open-source web server that supports Windows, MacOS X and a variety of Linux distributions. Hiawatha was focused on performance and is used in place of larger, more complex web servers. The fetch_request is vulnerable due to improper handling of HTTP headers regarding content length and transfer encoding. Tomahawk is a component of the Hiawatha web server which is vulnerable to authentication timing attack due to usage of ‘strcmp’ and may allow a local attacker to access the management client. The double free in the XSLT show_index function is a memory handling problem. The developer acknowledges the vulnerabilities and has tested the update to ensure all three are mitigated or remediated. Hiawatha is no longer actively supported by the developer, but the developer acknowledges the vulnerabilities and has included mitigations and remediations to all three vulnerabilities in the next release.
Description
CVE-2025-57783 A request smuggling vulnerability caused by improper header parsing has been identified in the fetch_request function of Hiawatha web server versions 8.5 through 11.7. This vulnerability allows an unauthenticated attacker to smuggle requests and access restricted resources managed by the server.
CVE-2025-57784 An authentication timing attack has been identified in the Tomahawk component of Hiawatha web server versions 8.5 through 11.7, which occurs due to the use of strcmp in the handle_admin function. This vulnerability allows a local attacker to access the management client.
CVE-2025-57785 A double free in the XSLT show_index function has been identified in Hiawatha web server version 10.8.2 through 11.7. This vulnerability allows an unauthenticated attacker to corrupt data, which may lead to arbitrary code execution.
Impact
Exploiting the request smuggling vulnerability may result in attackers bypassing authentication, hijack user sessions or inject malicious payloads into requests.
Exploiting the timing ‘strcmp’ function in the handle_admin function may result in password attempts to measure the time for each attempt, then assume the password is known by the longest attempt which would match more characters. This vulnerability may be time consuming to exploit.
Exploiting the double free error is when a program tries to free memory in the same location more than once. In a web server the XSLT show_index function may originate from an error in memory management during the execution of the XSLT which may result in corrupt data leading to the execution of arbitrary code.
Solution
Install updated version when distributed by Hiawatha.

VU#706118: Workhorse Software Services, Inc. software prior to version 1.9.4.48019, default deployment is vulnerable to multiple issues.

VU#706118: Workhorse Software Services, Inc. software prior to version 1.9.4.48019, default deployment is vulnerable to multiple issues.

Overview
Workhorse Software Services, Inc municipal accounting software prior to version 1.9.4.48019 contains design flaws that could allow unauthorized access to sensitive data and facilitate data exfiltration. Specifically, database connection information is stored in plaintext alongside the application executable, and the software allows unauthenticated users to create unencrypted database backups from the login screen.
Description
Two primary issues exist in Workhorse’s design:
Plaintext Database Connection String
CVE-2025-9037 The software stores the SQL Server connection string in a plaintext configuration file located alongside the executable. In typical deployments, this directory is on a shared network folder hosted by the same server running the SQL database. If SQL authentication is used, credentials in this file could be recovered by anyone with read access to the directory.
Unauthenticated Database Backup Functionality
CVE-2025-9040 The application’s “File” menu, accessible even from the login screen, provides a database backup feature that executes an MS SQL Server Express backup and allows saving the resulting .bak file inside an unencrypted ZIP archive. This backup can be restored to any SQL Server instance without requiring a password.
An attacker with physical access to a workstation, malware capable of reading network files, or via social engineering could exfiltrate full database backups without authentication.
Impact
An attacker could obtain the complete database, potentially exposing sensitive personally identifiable information (PII) such as Social Security numbers, full municipal financial records, and other confidential data. Possession of a database backup could also enable data tampering, potentially undermining audit trails and compromising the integrity of municipal financial operations.
Solution
The CERT/CC recommends updating the software to version 1.9.4.48019 as soon as possible.
Other potential mitigations include:
* Restricting access to the application directory via NTFS permissions
* Enabling SQL Server encryption and Windows Authentication
* Disabling the backup feature at the vendor or configuration level
* Using network segmentation and firewall rules to limit database access
