What the vulnerability does
The wpForo Forum plugin for WordPress is vulnerable to SQL Injection via the 'referer' parameter in all versions up to, and including, 2.4.17. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Explanation of Vulnerability in Simple Terms
wpForo Forum versions 2.4.17 and earlier contain a SQL injection vulnerability in an unauthenticated network-accessible component. An attacker can craft malicious input to read sensitive data from the forum database, including user credentials and private messages. No user interaction is required. Update to a version newer than 2.4.17.
What an attacker can do
Read sensitive data from the forum database without authentication, including user credentials and private messages.
Potential impact on your site
Forum user data, credentials, and private messages can be extracted by remote attackers without logging in.
Conditions required to exploit
Network access to the wpForo installation; no authentication or user interaction required.
