Vulnerability Overview

The File Manager Pro plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 8.3.4 via the mk_check_filemanager_php_syntax AJAX function. This makes it possible for authenticated attackers, with subscriber access and above, to execute code on the server. Version 8.3.5 introduces a capability check that prevents users lower than admin from executing this function.

Technical Analysis

REMEDIATION: Update to version 8.3.5, or a newer patched version --- IDENTIFIER: CWE-94 (Improper Control of Generation of Code ('Code Injection')) The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
