Technical details
The vulnerability is a format string flaw in Active Directory Certificate Services that permits information disclosure. An authenticated attacker can craft malicious input containing format string specifiers to read arbitrary memory contents from the AD CS service. The attack requires network access to AD CS and valid authentication credentials. Successful exploitation allows the attacker to leak sensitive data such as credentials, encryption keys, or other confidential information stored in the service's memory. Patches are available from Microsoft.
