Cisco Ise Passive Identity Connector
An issue exists in the Online Certificate Status Protocol (OCSP) responder—a protocol used for obtaining the real-time revocation status of digital certificates. The flaw is caused by missing authentication on a function of the OCSP responder, which allows an unauthenticated remote attacker to send a crafted request to an affected device. A successful exploit enables the attacker to trigger an administrative reload of the OCSP responder certificate and key material on demand.
