Telenia TVox 26.5.3 Privilege Escalation via Insecure sudoers Configuration

Published Aug 3, 2026 CVSS 4.0 · 8.5 High EPSS < 1% KEV · Not listed
Description
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.
