At a glance

CVE-2023-7264 is a high-severity Weak Password Recovery Mechanism for Forgotten Password vulnerability in the Build App Online WordPress plugin, affecting versions <= 1.0.22. 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 1.0.23; sites on affected versions should update now. Disclosed December 2023, reported by Ram.

Vulnerability Overview

The Build App Online plugin for WordPress is vulnerable to account takeover due to a weak password reset mechanism in all versions up to, and including, 1.0.22. This makes it possible for unauthenticated attackers to reset the password of arbitrary users by guessing an 4-digit numeric reset code.

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

Reaching this weakness in Build App Online <= 1.0.22 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 Build App Online the fix is 1.0.23: builds <= 1.0.22 are affected, anything from 1.0.23 onward is not.

Remediation

Update to version 1.0.23, 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: Build App Online 1.0.23 closes this, and updating the plugin is the step that ends it.
