CVE-2024-24091Network attack vector

Unauthenticated command execution via file upload

Published Feb 8, 2024 · Updated Apr 24, 2025

OS command injection in Yealink Meeting Server before 26.0.0.66 allows remote attackers to execute commands via the file upload interface. Yealink has not published the affected endpoint, parameter, or command-construction operation that mishandles uploaded input. The network path requires no authentication, and successful exploitation permits arbitrary operating-system command execution on the server.
