FAQ

What privileges could be gained by an attacker who successfully exploited the vulnerability? An attacker who successfully exploited this vulnerability could gain domain administrator privileges. According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability? An authenticated attacker could exploit this vulnerability with LAN access. According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability? An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities. How could an attacker exploit this vulnerability? To exploit this vulnerability, an attacker would need to predict the name of a new domain controller and rename their computer to match it. They would then establish a secure channel and keep it active while renaming their computer back to its original name. Once the new domain controller is promoted, the attacker could use the secure channel to impersonate the domain controller and potentially compromise the entire domain.
