The scan output in line 06 indicates that OCSP Must-Staple is not supported. This vulnerability exposes the application to attacks where an attacker can exploit the trust relationship between the client and the server by forging certificate revocation statuses. When OCSP stapling is not enforced, a client cannot reliably check if a certificate has been revoked, potentially allowing attackers to exploit this gap. CASP+ discusses the importance of certificate validation mechanisms such as OCSP (Online Certificate Status Protocol) to prevent man-in-the-middle and trust-exploiting attacks.
