Ultimate Auction Pro WordPress Plugin | Up to and including 1.5.2
How the Exploit Works
The exploit takes advantage of the ‘auction_id’ parameter in the Ultimate Auction Pro plugin, which lacks sufficient escaping and preparation on the SQL query. An attacker could inject malicious SQL statements into the already existing queries, allowing them to manipulate the database and extract sensitive information.
Conceptual Example Code
Here is a conceptual example of how this vulnerability might be exploited:
GET /wp-content/plugins/ultimate-auction/auction.php?auction_id=1 OR 1=1 UNION SELECT username, password FROM wp_users HTTP/1.1
Host: target.example.comIn this example, the exploit would return all usernames and passwords from the `wp_users` table. The “1 OR 1=1” part of the query always evaluates to true, effectively bypassing any checks on the ‘auction_id’ parameter.
Mitigation Guidance
Users are advised to apply the vendor patch as soon as possible. If the patch cannot be applied immediately, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation to detect and block malicious SQL queries.
