Descriptions

A CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability exists in C-Bus Toolkit (V1.15.7 and prior) that could allow a remote code execution when processing config files.

Una CWE-22: Se presenta una vulnerabilidad de Limitación Inapropiada de un Nombre de Ruta para un Directorio Restringido ("Path Traversal") en C-Bus Toolkit (versiones V1.15.7 y anteriores) que podría permitir una ejecución de código remota al procesar archivos de configuración

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Schneider Electric C-Bus Toolkit. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the processing of commands sent to the C-Gate 2 Service. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
