At a glance

CVE-2024-9302 is a high-severity Weak Password Recovery Mechanism for Forgotten Password vulnerability in the App Builder WordPress plugin, affecting versions <= 5.3.7. 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 5.3.8; sites on affected versions should update now. Disclosed October 2024, reported by wesley (wcraft).

Vulnerability Overview

The App Builder – Create Native Android & iOS Apps On The Flight plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 5.3.7. This is due to the verify_otp_forgot_password() and update_password() functions not having enough controls to prevent a successful brute force attack of the OTP to change a password, or verify that a password reset request came from an authorized user. This makes it possible for unauthenticated attackers to generate and brute force an OTP that makes it possible to change any users passwords, including an administrator.

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-640: Weak Password Recovery Mechanism for Forgotten Password

App Builder <= 5.3.7 carries this weakness at verify_otp_forgot_password(), and reaching it takes a caller who can reach the endpoint. A weak password recovery mechanism means the path that lets someone back into an account without their password is easier to complete than the password itself.

An attacker takes over an account through the recovery flow without ever seeing the password, and on an administrator account that is full control of the site. For App Builder the fix is 5.3.8: builds <= 5.3.7 are affected, anything from 5.3.8 onward is not.

Remediation

Update to version 5.3.8, 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: App Builder 5.3.8 closes this, and updating the plugin is the step that ends it.
