CVE-2021-44515Known exploitationPublic exploitNetwork attack vector

Unauthenticated code execution via unsecured STATE_ID routes

Published Dec 12, 2021 · Updated Oct 21, 2025

Authentication bypass in ManageEngine Desktop Central affected builds allows remote attackers to execute arbitrary code via crafted requests. The web.xml security constraint omits /STATE_ID/*, so StateFilter forwards unauthenticated requests to endpoints including agentLogUploader. No credentials or user interaction are required; successful exploitation permits arbitrary server-side file writes and code execution.
