| Title | StableBit StableBit Scanner 2.6.13.4088 Local Privilege Escalation |
|---|
| Description | StableBit Scanner exposes a local .NET Remoting IPC endpoint from ScannerService, which runs as LocalSystem. A standard local user can connect to \\.\pipe\Scanner2_Comm, perform a benign remoting call, and send a BinaryFormatter gadget as the object TaskState argument to Comm1.StartTask(Guid, object, Guid[]).
As a result, arbitrary command execution under SYSTEM privilege can be achieved. |
