Heap-based buffer overflow in Windows Volume Shadow Copy allows an unauthorized attacker to elevate privileges with a physical attack.
AnalysisAI
Privilege escalation to SYSTEM level is achievable in Windows Volume Shadow Copy Service (VSS) across a broad range of Microsoft Windows and Windows Server releases, from Server 2012 through Windows 11 25H2 and Server 2025. The root cause is a heap-based buffer overflow (CWE-122) exploitable by an unauthenticated attacker with physical access to the target machine, yielding full C:H/I:H/A:H impact. …
