Kerentanan OWASP Top Ten 2017 Category A9 - Using Components with Known Vulnerabilities. Skor CVSS 3.1 5.9 (Medium) menurut redhat.com.

Deskripsi (NVD)

A flaw was found in Netty's Online Certificate Status Protocol (OCSP) Client. The client fails to verify the 'id-kp-OCSPSigning' Extended Key Usage (EKU) in OCSP responder certificates. A remote attacker, holding any valid certificate issued by the same Certificate Authority (CA), can exploit this by forging 'GOOD' OCSP responses for revoked certificates. This bypasses certificate revocation checks, allowing applications using Netty's OCSP Client to accept certificates that should have been revoked, leading to an authorization bypass.
