Wolf CMS versions through 0.8.3.1 have a remote code execution vulnerability in the FileManagerController. Authenticated attackers with the file_manager_mkfile capability can create arbitrary PHP files due to missing file extension validation in the create_file() and save() functions. These malicious files can be placed in the web-accessible FILES_DIR directory and executed via HTTP requests.
AI Analysis
Technical Summary
The vulnerability in Wolf CMS up to version 0.8.3.1 arises from insufficient validation of file extensions in the FileManagerController's create_file() and save() functions. This allows authenticated users with specific permissions to upload arbitrary PHP files into a web-accessible directory, enabling remote code execution when these files are accessed over HTTP. The issue is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type). No patch or official remediation details are provided in the available data.
Potential Impact
Successful exploitation allows an authenticated attacker to execute arbitrary PHP code on the server hosting Wolf CMS. This can lead to full system compromise, data theft, or further attacks within the affected environment. The vulnerability requires authentication and the file_manager_mkfile capability, limiting exploitation to authorized users.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to users with the file_manager_mkfile capability and monitor for suspicious file uploads. Consider disabling or restricting the FileManagerController functionality if possible.
