Improper input validation in Windows Active Directory allows an authorized attacker to execute code over an adjacent network.
How could an attacker exploit this vulnerability? To exploit this vulnerability, an authenticated attacker would need to send a specially crafted RPC call to an RPC host. This could result in remote code execution on the server side with the same permissions as the RPC service. According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires that an attacker needs to be in the same restricted Active Directory domain as the target system. The attack surface is not reachable from broader networks, which is why the attack vector is considered adjacent (AV:A).
