CVE-2022-26251Public exploitNetwork attack vector

Authenticated remote code execution via upload trigger

Published Apr 6, 2022 · Updated Jul 9, 2026

Improper privilege management in Synametrics Synaman 5.1 and earlier allows remote authenticated users to execute arbitrary code via the HTTP interface. The web UI lets an authenticated administrator create writable shares, upload an executable, and configure a trigger that runs it as the SYSTEM service account. Administrator authentication and network access to the HTTP service are required; successful abuse executes attacker code with SYSTEM privileges and can compromise the server.
