Technical details

A privilege escalation vulnerability exists in Windows Server Update Service (WSUS) due to missing authentication for a critical function (CWE-306). An attacker who is already authenticated to the network with low-privileged credentials can exploit this over the network without any user interaction. Successful exploitation allows the attacker to elevate their privileges, potentially gaining administrative control over the update infrastructure. Microsoft has released security updates for various versions of Windows 10 and Windows Server (2012 through 2019) to address this issue.
