CVE-2023-36033 is an elevation-of-privilege vulnerability in the Windows Desktop Window Manager (DWM) Core Library. The provided content identifies it as a Windows DWM Core Library flaw that was exploited in the wild as a zero-day and could be used to obtain SYSTEM privileges. Supporting analysis in the content states that exploitation involves shellcode execution inside dwm.exe under the Window Manager\DWM security context, followed by a privilege-escalation chain that can include dropping a DLL to disk, hooking kernelbase!MapViewOfFile in dwm.exe, triggering logoff, and abusing LogonUI.exe’s interaction with dwm.exe and Direct Composition object unmarshalling to load an attacker-controlled DLL. The content also notes that a later DWM zero-day reused an exploitation process identical to CVE-2023-36033, reinforcing that this bug was in the DWM attack surface reachable from a lower-privileged context. While Microsoft’s title only labels it as an EoP issue, the exploit behavior described in the supplied material is consistent with a memory-safety flaw in DWM; based on the provided context, CWE-416 is the closest supported classification, though the exact root cause is not explicitly stated in the content.
