A vulnerability in the Online Certificate Status Protocol (OCSP) responder of Cisco ISE and Cisco ISE-PIC could allow an unauthenticated, remote attacker to cause an administrative reload of the OCSP responder certificate and key material. This vulnerability is due to missing authentication on a function of the OCSP responder. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to cause the OCSP responder to reload certificate and key material on demand.
