At a glance

CVE-2024-3729 is a critical-severity Not Failing Securely ('Failing Open') vulnerability in the Frontend Admin by DynamiApps WordPress plugin, affecting versions <= 3.19.4. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.19.5; sites on affected versions should update now. Disclosed April 2024, reported by István Márton.

Vulnerability Overview

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to improper missing encryption exception handling on the 'fea_encrypt' function in all versions up to, and including, 3.19.4. This makes it possible for unauthenticated attackers to manipulate the user processing forms, which can be used to add and edit administrator user for privilege escalation, or to automatically log in users for authentication bypass, or manipulate the post processing form that can be used to inject arbitrary web scripts. 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, with low attack complexity — no special timing or configuration is needed, 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-636: Not Failing Securely ('Failing Open')

When the product encounters an error condition or failure, its design requires it to fall back to a state that is less secure than other options that are available, such as selecting the weakest encryption algorithm or using the most permissive access control restrictions.

Remediation

Update to version 3.19.5, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Frontend Admin by DynamiApps 3.19.5 closes this, and updating the plugin is the step that ends it.
