CVE-2024-11656Public exploitNetwork attack vector

Authenticated command execution via diag_ping6 injection

Published Nov 25, 2024 · Updated Nov 26, 2024

Command injection in EnGenius ENH1350EXT, ENS500-AC, and ENS620EXT 20241118 and earlier allows remote authenticated users to execute commands. The /admin/network/diag_ping6 handler incorporates the attacker-controlled diag_ping6 value into an operating-system command without neutralizing command separators. Administrative privileges are required, and successful exploitation can read or modify appliance data and interrupt service.
