CVE-2025-52904File Browser: Command Execution not Limited to Scope
High 8.0
In plain English
A high-severity command injection in filebrowser from filebrowser. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 1.1% (higher than 66% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. In versions of the web application on the 2.x branch, all users have a scope assigned, and they only have access to the files within that scope. The Command Execution feature of Filebrowser allows the execution of shell commands which are not restricted to the scope, potentially giving an attacker read and write access to all files managed by the server. Until this issue is fixed, the maintainers recommend to completely disable `Execute commands` for all accounts. Since the command execution is an inherently dangerous feature that is not used by all deployments, it should be possible to completely disable it in the application's configuration. This feature has been disabled by default for all installations from v2.33.8 onwards, including for existent installations. To exploit this vulnerability, the instance administrator must turn on a feature and ignore all the warnings about known vulnerabilities.
