Summary
Saurus CMS Community Edition contains an unauthenticated open redirect vulnerability in the logout handling code in classes/port.inc.php, where the url parameter supplied via GET or POST is passed directly to the Location header without domain allowlist, scheme validation, or relative path enforcement. Attackers can craft a malicious logout URL containing an arbitrary external domain or javascript: URI scheme to redirect authenticated users to attacker-controlled phishing pages after session destruction, enabling credential theft and OAuth redirect abuse.
Risk Assessment
Risk of redirecting users to malicious phishing pages, potentially leading to credential theft and account compromise.
Recommendation
Upgrade Saurus CMS to a version that includes a fix for this vulnerability or manually add URL validation in the code.
