Descriptions

Triangle MicroWorks SCADA Data Gateway Event Log Directory Traversal Arbitrary File Creation Vulnerability. This vulnerability allows remote attackers to create arbitrary files on affected installations of Triangle MicroWorks SCADA Data Gateway. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.

The specific flaw exists within the creation of event logs. 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 in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-20534.

Vulnerabilidad de creación de archivos arbitrarios de recorrido de directorio de registro de eventos de puerta de enlace de datos SCADA de Triangle MicroWorks. Esta vulnerabilidad permite a atacantes remotos crear archivos arbitrarios en las instalaciones afectadas de Triangle MicroWorks SCADA Data Gateway. Aunque se requiere autenticación para aprovechar esta vulnerabilidad, se puede omitir el mecanismo de autenticación existente. La falla específica existe en la creación de registros de eventos. El problema se debe a la falta de validación adecuada de una ruta proporcionada por el usuario antes de usarla en operaciones de archivos. Un atacante puede aprovechar esto junto con otras vulnerabilidades para ejecutar código en el contexto raíz. Era ZDI-CAN-20534.
