At a glance

CVE-2024-4611 is a high-severity Improper Check or Handling of Exceptional Conditions vulnerability in the AppPresser WordPress plugin, affecting versions <= 4.3.2. 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 4.4.0; sites on affected versions should update now. Disclosed May 2024, reported by István Márton.

Vulnerability Overview

The AppPresser plugin for WordPress is vulnerable to improper missing encryption exception handling on the 'decrypt_value' and on the 'doCookieAuth' functions in all versions up to, and including, 4.3.2. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they previously used the login via the plugin API. This can only be exploited if the 'openssl' php extension is not loaded on the server.

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-703: Improper Check or Handling of Exceptional Conditions

The product does not properly anticipate or handle exceptional conditions that rarely occur during normal operation of the product.

Remediation

Update to version 4.4.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: AppPresser 4.4.0 closes this, and updating the plugin is the step that ends it.
