Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Validates redirect target URLs supplied to cas-auth so that only trusted destinations are accepted, directly blocking the open redirect.

AC-4 Information Flow Enforcement partial match
prevent

Enforces policy on allowed information flows, restricting redirect destinations to approved domains and thereby limiting phishing/credential-theft vectors.

SI-2 Flaw Remediation good match
prevent

Requires prompt application of the vendor patch (3.17.0) that removes the vulnerable default cas-auth redirect behavior.
