CVE-2017-20246Public exploitNetwork attack vector

Database reads via unescaped kc_ad parameter

Published Jun 9, 2026 · Updated Jun 9, 2026

SQL injection in Missilesilo KittyCatfish Ads 2.2 allows remote attackers to read database contents through the kc_ad GET parameter. The base.css.php and kittycatfish.php endpoints use the unescaped kc_ad value in SQL, enabling boolean-based and time-based blind queries. No authentication or user interaction is required; arbitrary database reads are demonstrated, while filesystem access depends on web-server misconfiguration.
