CVE-2025-23173Network attack vector

Unauthenticated code execution via exposed websockify service

Published Jun 18, 2025 · Updated Jun 23, 2025

Improper access control in Versa Director allows remote attackers to execute code through the websockify service on TCP port 6080. The default configuration exposes websockify directly to the internet instead of limiting it to the authenticated Director GUI. Versa has not disclosed the specific websockify weakness or crafted input used to reach code execution; exposure of port 6080 is the required gate.
