Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Open Redirect through a substring check rather than a host check at str contains($referer, CACTI PATH URL). When the user's login opts == '1' (redirect to referer after login), the function used $ SERVER['HTTP REFERER'] directly. An attacker could craft a referer such as https://evil.com/cacti/. Where CACTI PATH URL is /cacti/, the substring matches and the user is redirected to evil.com after login. The pre-existing validate redirect url() helper at lib/html utility.php performed proper validation but was not invoked from auth login redirect(). This issue has been fixed in version 1.2.31.
