{"id":"CVE-2026-13162","kind":"vulnerability","aliases":["CVE-2026-13162"],"related":[],"title":"CoreTec device: time-zone setting lets authenticated users run OS commands","description":"An OS command vulnerability exists in CoreTec product that allows authenticated users with certain roles to execute arbitrary system commands with full control over the device. The vulnerability exists in the configuration daemon's time synchronization handler, which is responsible for setting the system time-zone. When processing time-zone configuration updates, the daemon constructs a shell command by concatenating user-supplied input without any sanitization or validation.","summary":"A configuration daemon in CoreTec products builds a shell command from the time-zone value without checking it.
