Descriptions

A local low privileged attacker can use an untrusted search path in a CHARX system utility to gain root
privileges.

Un atacante local con pocos privilegios puede utilizar una ruta de búsqueda que no sea de confianza en una utilidad del sistema CHARX para obtener privilegios de root.

This vulnerability allows local attackers to escalate privileges on affected installations of Phoenix Contact CHARX SEC-3100 devices. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the charx_set_timezone binary. The issue results from executing a program from an untrusted location. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root.
