Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Bitrix24 through 25.100.300 allows Remote Code Execution because an actor with SOURCE/WRITE permissions for the Translate Module can upload and execute code by sending a PHP file and a .htaccess file. NOTE: this is disputed by the Supplier because this is intended behavior for the high-privileged users who can upload new translated pages to the website.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Bitrix24's Translate Module allows users with SOURCE/WRITE permissions to upload files including PHP scripts and .htaccess configurations. This enables Remote Code Execution by uploading executable PHP files that can then be accessed via the web server. The vulnerability stems from insufficient validation of uploaded file types in the translation upload functionality.

MitigationRestrict or blacklist PHP file uploads in the Translate Module, store uploaded files outside the web root or with execute permissions disabled, and implement strict file type validation. Alternatively, refactor the translation storage mechanism to use non-PHP formats.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Bitrix24 installation presence
    Search for Bitrix24 core files or directories (e.g., index.php with Bitrix signatures, /bitrix/ directory, or configuration files containing 'bitrix24' in web root)
    Affected if Bitrix24 is installed in the environment
  2. Verify Translate Module is installed and active
    Check for the presence of the translation module component in the Bitrix24 module directory or administrative interface
    Affected if The Translate Module is present and enabled in Bitrix24
  3. Identify users with SOURCE/WRITE permissions
    Review user roles and permissions within the Translate Module administrative panel to locate accounts with SOURCE or WRITE access levels
    Affected if Any user account has SOURCE or WRITE permissions in the Translate Module
  4. Test file upload functionality in Translate Module
    Using an account with SOURCE/WRITE permissions, attempt to upload a test file through the translation upload feature to verify the endpoint accepts files
    Affected if The file upload functionality in the Translate Module is accessible and accepts file uploads
  5. Verify uploaded files are served from web-accessible location
    Check the storage path of uploaded translation files to determine if they are placed within the web document root and accessible via HTTP
    Affected if Uploaded translation files are stored in a web-accessible directory and can be retrieved via the web server

A user is affected if Bitrix24 with the Translate Module is installed, the module accepts file uploads from users with SOURCE/WRITE permissions, and uploaded files are served from a web-accessible location allowing PHP execution.
