ITW EXPLOIT VulnCheck KEV

The LearnPress plugin for WordPress is vulnerable to time-based SQL Injection via the ‘order_by’ parameter in all versions up to, and including, 4.2.5.7 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.

condition: contains_all(header, "lp_session_guest=", "application/json") AND contains_all(body, "status\":\"success", "No courses were found")

• → Requests exploiting this vulnerability are unauthenticated; look for requests carrying the 'lp_session_guest=' cookie header alongside 'application/json' content-type as a fingerprint of active exploitation.
• → Successful blind/time-based SQL injection responses return a JSON body containing both 'status":"success' and 'No courses were found'; correlate these response body strings with suspicious order_by parameter values to identify exploitation.

• · The rule fingerprint (digest) embedded in the detection rule should be validated against the canonical rule source to ensure the rule has not been tampered with before deployment.
• · All versions up to and including 4.2.5.7 of LearnPress are affected; ensure version-based filtering is applied when scoping detection to avoid false positives on patched installations. ↗
