FAQ
According to the CVSS metric, privileges required is high (PR:H). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires the attacker or targeted user to have both domain user and delegate management permissions on a non-default DFS namespace.
FAQ
How could an attacker exploit this vulnerability? An attacker could exploit a DFS namespace (non-default) out-of-bound write vulnerability that results in heap corruption, which could then be used to perform arbitrary code execution on the server's dfssvc.exe process which runs as SYSTEM user.
FAQ
According to the CVSS metric, attack complexity is high (AC:H). What does that mean for this vulnerability? In a real-world attack scenario, a domain admin would have to configure their DFS namespace in such a way to add a low privileged domain user to the delegate management permission on a certain DFS namespace. In essence, a successful exploitation of this vulnerability would require a non-default and unlikely configuration.
FAQ
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.
