SYSTEM code execution via writable named pipe
Published Aug 3, 2026 · Updated Aug 3, 2026
Command injection in Razer RzUpdateService 1.10.14.0 allows local users to execute arbitrary code as SYSTEM through a writable named pipe. The service grants Everyone read/write pipe access, decodes message ID 2 into lpThreadParameter, and passes attacker-controlled data at offset 520 to CreateProcessW as its command line. Low-privileged Windows and pipe access are required; no user interaction is needed, and successful exploitation runs arbitrary commands as SYSTEM.
