At a glance

CVE-2023-6825 is a critical-severity Relative Path Traversal vulnerability in the File Manager Pro WordPress plugin, affecting versions <= 8.3.4. It carries a CVSS score of 9.9 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 8.3.5; sites on affected versions should update now. Disclosed March 2024, reported by Tobias Weißhaar (kun_19).

Vulnerability Overview

The File Manager and File Manager Pro plugins for WordPress are vulnerable to Directory Traversal in versions up to, and including version 7.2.1 (free version) and 8.3.4 (Pro version) via the target parameter in the mk_file_folder_manager_action_callback_shortcode function. This makes it possible for attackers to read the contents of arbitrary files on the server, which can contain sensitive information and to upload files into directories other than the intended directory for file uploads. The free version requires Administrator access for this vulnerability to be exploitable. The Pro version allows a file manager to be embedded via a shortcode and also allows admins to grant file handling privileges to other user levels, which could lead to this vulnerability being exploited by lower-level users.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-23: Relative Path Traversal

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as .. that can resolve to a location that is outside of that directory.

Remediation

Update to version 8.3.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to File Manager Pro: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: File Manager Pro 8.3.5 closes this, and updating the plugin is the step that ends it.
