Technical details

This vulnerability is classified as a use-after-free (CWE-416) and a race condition (CWE-362) within Windows Remote Desktop Services. An attacker with low-privileged network access can exploit improper synchronization during concurrent execution to trigger a memory corruption state. Successful exploitation allows the attacker to elevate their privileges to a higher level, potentially gaining full system control. The attack vector is network-based and does not require user interaction, though it does require initial authentication (PR:L). Microsoft has released security updates to address this issue across affected Windows and Windows Server versions.
