Telenia TVox 26.5.3 Privilege Escalation via Insecure sudoers Configuration

AI Analysis

No AI analysis yet.

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.
