CVE-2026-67609
HighCVSS 7.8Summary
Telenia Software TVox versions 26.5.3 and prior 26.x, and 24.9.21 and prior 24.x, contain a privilege escalation vulnerability. An insecure sudoers configuration in /etc/sudoers.d/telenia grants the apache user NOPASSWD execution of /bin/nice, which can be leveraged to execute arbitrary commands as root.
Risk Assessment
An attacker with access to the apache account can gain full root privileges, leading to complete system compromise. This can result in data confidentiality, integrity, and availability breaches.
Recommendation
Immediately modify the /etc/sudoers.d/telenia file to remove or restrict the apache user's ability to execute /bin/nice. Also update TVox to the latest version.

See all- 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.
- CVE-2026-64827Critical
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.
Original NVD description (English source)
Telenia Software TVox 26.5.3 and prior 26.x versions, and 24.9.21 and prior 24.x versions, contain a privilege escalation vulnerability that allows attackers with access to the apache account to execute arbitrary commands as root by exploiting an insecure sudoers configuration in /etc/sudoers.d/telenia. The configuration grants the apache user NOPASSWD execution of /bin/nice, which can be leveraged to invoke arbitrary commands, enabling full root-level command execution without supplying a password.
