At a glance

CVE-2023-3814 is a medium-severity Improper Access Control vulnerability in the Advanced File Manager WordPress plugin, affecting versions <= 5.1. It carries a CVSS score of 6.6 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 5.1.1; sites on affected versions should update now. Disclosed August 2023, reported by Dmitrii Ignatyev.

Vulnerability Overview

The Advanced File Managerplugin for WordPress is vulnerable to improper access control in versions up to, and including, 5.1. This makes it possible for authenticated attackers, with administrator-level permissions and above, to access the filesystem on multisite installations. This only affects multi-site installations.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-284: Improper Access Control

Reaching this weakness in Advanced File Manager <= 5.1 takes an account at Administrator level or above. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For Advanced File Manager the fix is 5.1.1: builds <= 5.1 are affected, anything from 5.1.1 onward is not.

Remediation

Update to version 5.1.1, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Advanced File Manager 5.1.1 closes this, and updating the plugin is the step that ends it.
