Summary
Telenia Software TVox 26.5.3 and prior 26.x versions, and 24.9.21 and prior 24.x versions, contain an authentication bypass vulnerability in set_env.php where the redirectToLoginAdminIRequestHaveAccessToken() function derives the current page name from PHP_SELF and skips authentication when the value matches 'login_admin.php'. Attackers can append '/login_admin.php' to the path of any target PHP script to cause the authentication check to pass and gain unauthenticated access to all PHP scripts under the manager HTML directory.
Risk Assessment
The risk includes unauthenticated access to all PHP scripts in the manager directory, potentially leading to compromise of the TVox system and access to configuration data.
Recommendation
It is recommended to immediately upgrade Telenia Software TVox to the latest version and implement fixes in the authentication logic to not rely on PHP_SELF.

- CVE-2026-67608High
Telenia Software TVox 26.5.3 and prior 26.x versions, and 24.9.21 and prior 24.x versions, contain an OS command injection vulnerability in action_audio.php that allows authenticated attackers to execute arbitrary operating system commands by passing an unsanitized pid parameter into an exec() call when the action parameter is set to checkProcess. Attackers can inject malicious OS commands through the pid request parameter to execute arbitrary commands with the privileges of the apache user.
