CVE-2025-64127 is a critical OS command injection vulnerability affecting Zenitel TCIV-3+ devices. The flaw is caused by insufficient sanitization of user-supplied input that is later incorporated into operating system command execution without adequate validation or neutralization. Because the vulnerable input can be reached remotely and does not require authentication, an attacker can send crafted requests that inject arbitrary shell command elements into the application's command-processing logic. Successful exploitation can result in remote arbitrary command execution on the affected device and compromise of the underlying system.
