CWE-646

Wowza Streaming Engine below 4.9.1 permits an authenticated Streaming Engine Manager administrator to define a custom application property and poison a stream target for high-privilege remote code execution.

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.3, the audio transcription upload endpoint takes the file extension from the user-supplied filename and saves the file under CACHE_DIR/audio/transcriptions/.. The /cache/{path} route serves these files via FileResponse, which sets Content-Type from the on-disk extension and emits no Content-Disposition. A verified user with the default-on chat.stt permission can upload a polyglot WAV+HTML file named pwn.html and trick any other user into opening the resulting URL — the response comes back as text/html and any embedded <script> runs in the Open WebUI origin. This vulnerability is fixed in 0.9.3.

Maho is a free and open source ecommerce platform. In Maho prior to 25.9.0, an authenticated staff user with access to the `Dashboard` and `Catalog\Manage Products` permissions can create a custom option on a listing with a file input field. By allowing file uploads with a `.php` extension, the user can use the filed to upload malicious PHP files, gaining remote code execution. Version 25.9.0 fixes the issue.

Authenticated File Upload in WordPress Download Manager <= 3.1.24 allows authenticated (Author+) users to upload files with a double extension, e.g. "payload.php.png" which is executable in some configurations. This issue affects: WordPress Download Manager version 3.1.24 and prior versions.

Symlink following in the installer for the Zoom Workplace VDI Plugin macOS Universal installer before version 6.3.14, 6.4.14, and 6.5.10 in their respective tracks may allow an authenticated user to conduct a disclosure of information via network access.

Matrix Tafnit v8 - CWE-646: Reliance on File Name or Extension of Externally-Supplied File

A CWE-646 “Reliance on File Name or Extension of Externally-Supplied File” vulnerability in the “iec61850” functionality of the web application allows a remote authenticated attacker to upload any arbitrary type of file into the device. This issue affects: AiLux imx6 bundle below version imx6_1.0.7-2.

picklescan before 0.0.22 only considers standard pickle file extensions in the scope for its vulnerability scan. An attacker could craft a malicious model that uses Pickle and include a malicious pickle file with a non-standard file extension. Because the malicious pickle file inclusion is not considered as part of the scope of picklescan, the file would pass security checks and appear to be safe, when it could instead prove to be problematic.

A vulnerability in the Lite Agent feature of Cisco Enterprise Chat and Email (ECE) could allow an authenticated, remote attacker to conduct browser-based attacks. To exploit this vulnerability, the attacker must have valid credentials for a user account with at least the role of Agent. This vulnerability is due to inadequate validation of file contents during file upload operations. An attacker could exploit this vulnerability by uploading a file that contains malicious scripts or HTML code, which the application could make available to other users to access. A successful exploit could allow the attacker to execute the contents of that file in the browser of a user and conduct browser-based attacks.&nbsp;

A low privileged remote attacker can upload arbitrary data masked as a png file to the affected device using the webserver API because only the file extension is verified.
