Local SYSTEM code execution via unsafe deserialization
Published Aug 7, 2026 · Updated Aug 7, 2026
Insecure deserialization in StableBit DrivePool 2.3.13.1687 allows local users to execute arbitrary code as LocalSystem through local IPC. DrivePoolService accepts an attacker-controlled BinaryFormatter object in Comm1.StartTask's TaskState argument over the StableBitDrivePool_Comm named pipe. A standard Windows user who can reach the local pipe can run code in the LocalSystem service context, enabling full local privilege escalation.
