Descriptions

This vulnerability allows remote attackers to overwrite arbitrary files on vulnerable installations of NetGain Systems Enterprise Manager 7.2.730 build 1034. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the org.apache.jsp.u.jsp.db.save_005fattrs_jsp servlet, which listens on TCP port 8081 by default. When parsing the id parameter, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to overwrite any files accessible to the Administrator. Was ZDI-CAN-5196.

Esta vulnerabilidad permite que atacantes remotos sobrescriban archivos arbitrarios en instalaciones vulnerables de NetGain Systems Enterprise Manager 7.2.730 build 1034. Aunque se requiere autenticación para explotar esta vulnerabilidad, el mecanismo de autenticación existente se puede omitir. El fallo específico existe en el servlet org.apache.jsp.u.jsp.db.save_005fattrs_jsp, que escucha en el puerto TCP 8081 por defecto. Cuando se analiza sintácticamente el parámetro id, el proceso no valida correctamente una ruta proporcionada por el usuario antes de emplearla en operaciones de archivo. Un atacante puede aprovechar esta vulnerabilidad para sobrescribir cualquier archivo accesible para el Administrador. Anteriormente era ZDI-CAN-5196.
