CVE-2021-46354Public exploitNetwork attack vector

Origin IP disclosure via attacker-directed server request

Published Feb 9, 2022 · Updated Jul 9, 2026

SSRF in Cybele Software Thinfinity VirtualUI 2.1.28.0, 2.1.32.1, and 2.5.26.2 allows remote attackers to expose its origin IP. The unauthenticated /cmd connect handler accepts an attacker-controlled destAddr value and makes the server contact that external endpoint. No credentials or user interaction are required, and the outbound request reveals the origin behind a CDN while reaching other server-accessible services.
