Technical details
A command injection vulnerability exists in the certificate revocation process of Key Manager Plus. An authenticated user with certificate management privileges can supply specially crafted input during Microsoft CA configuration, which is later executed without proper sanitization during certificate revocation operations. An attacker can execute arbitrary operating system commands on Windows endpoints hosting the certificate agent, running with the privileges of the agent service.
