Description
The File Manager plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the connector function in all versions from 6.0 - 6.9. This makes it possible for authenticated attackers, with subscriber-level access and above, to read and delete arbitrary files on the server, which can lead to remote code execution when the right file is deleted (such as wp-config.php). The bypass is triggered by passing cmd=rm or cmf=file in the URL query string of a POST request: elFinder's bind registration reads the command exclusively from $_POST and therefore never registers the rm.pre permission handler, while the dispatcher reads from the merged $_GET+$_POST superglobal and executes the rm or file command unchecked against a volume that defaults to ABSPATH.

AI Analysis

Impact

The File Manager plugin for WordPress permits authenticated users at the subscriber level or higher to delete or read arbitrary files on the server, thanks to insufficient input validation in the connector function. This is a classic missing authorization flaw, classified as CWE‑862, and can enable remote code execution if critical files such as wp-config.php are removed.

Affected Systems

Bitpressadmin’s File Manager plugin for WordPress versions 6.0 through 6.9 are impacted. No operating system or PHP version restrictions are listed, meaning any WordPress site running any of these releases is potentially vulnerable.

Risk and Exploitability

The CVSS score is 8.8, reflecting high severity. The EPSS score is not available, and the flaw is not listed in the CISA KEV catalog. Exploitation requires an attacker to be authenticated with at least subscriber access and then issue a POST request to the ajax handler with a query string containing cmd=rm or cmd=file; because the dispatcher reads from the merged superglobal array, the command runs unchecked against the server’s ABSPATH, allowing arbitrary deletion or reading of files.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the File Manager plugin to version 6.9.1 or later, which eliminates the missing authorization check.
  • If a patch cannot be applied immediately, restrict or disable the ajax endpoint (admin-ajax.php) for users with subscriber-level or higher privileges, or remove the rm/file commands from the Ajax dispatcher until the plugin is patched.
  • Review server file permissions and monitor logs for unexpected calls to admin-ajax.php containing cmd=rm or cmd=file, as these may signify exploitation attempts.
