Advanced File Manager 5.2.12 - 5.2.13 - Authenticated (Subscriber+) Arbitrary File Upload

The Advanced File Manager plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'fma_local_file_system' function in versions 5.2.12 to 5.2.13. This makes it possible for authenticated attackers, with Subscriber-level access and above and upload permissions granted by an administrator, to upload arbitrary files on the affected site's server which may make remote code execution possible. The function can be exploited only if the "Display .htaccess?" setting is enabled.

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Advanced File Manager 5.2.14 closes this, and updating the plugin is the step that ends it.
