Description

The Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots plugin for WordPress is vulnerable to generic SQL Injection via 'group_id' Message Meta Parameter in all versions up to, and including, 3.0.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the BuddyBoss Platform plugin to be installed with its Social Groups component disabled, a state that persists on any site that has previously toggled the Groups component off since BuddyBoss does not drop the wp_bp_groups table upon deactivation.

Exploitability

CWE

KEV
KEV Icon
CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability is a SQL Injection flaw in the Better Messages WordPress plugin. It allows authenticated attackers with subscriber-level access or higher to inject malicious SQL queries via the 'group_id' parameter. This happens due to improper escaping of user input and lack of query preparation. The attack can extract sensitive data from the database.

Impact Analysis

If you use the Better Messages plugin, attackers could steal sensitive data from your WordPress database. They need only subscriber-level access, which is a low barrier. The attack could expose user information, messages, or other confidential data stored in the database.

Compliance Impact

This vulnerability could lead to data breaches, violating GDPR and HIPAA requirements for protecting personal and health data. Organizations may face fines, legal penalties, and reputational damage if sensitive data is exposed due to this flaw.

Mitigation Strategies

Update the Better Messages plugin to the latest version, which addresses the SQL injection vulnerability. If immediate update is not possible, disable the plugin temporarily until patched. Ensure the BuddyBoss Platform plugin's Social Groups component is enabled to avoid exploitation conditions.
