At a glance

CVE-2024-0761 is a high-severity Use of Insufficiently Random Values vulnerability in the File Manager WordPress plugin, affecting versions <= 7.2.1. It carries a CVSS score of 8.1 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 7.2.2; sites on affected versions should update now. Disclosed January 2024, reported by Yuki Haruma.

Vulnerability Overview

The File Manager plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 7.2.1 due to insufficient randomness in the backup filenames, which use a timestamp plus 4 random digits. This makes it possible for unauthenticated attackers, to extract sensitive data including site backups in configurations where the .htaccess file in the directory does not block access.

Technical Analysis

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

CWE-330: Use of Insufficiently Random Values

The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers.

Remediation

Update to version 7.2.2, 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: File Manager 7.2.2 closes this, and updating the plugin is the step that ends it.
