Descriptions

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of NetGain Systems Enterprise Manager 7.2.699 build 1001. 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.restore.download_005fdo_jsp servlet, which listens on TCP port 8081 by default. When parsing the filename parameter, the process does not properly validate 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 Administrator. Was ZDI-CAN-5100.

Esta vulnerabilidad permite que atacantes remotos revelen información sensible en instalaciones vulnerables de NetGain Systems Enterprise Manager 7.2.699 build 1001. 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.restore.download_005fdo_jsp, que escucha en el puerto TCP 8081 por defecto. Cuando se analiza sintácticamente el parámetro filename, el proceso no valida correctamente una ruta proporcionada por el usuario antes de emplearla en operaciones de archivo. Un atacante podría aprovecharse de esta vulnerabilidad y otras para ejecutar código en el contexto del Administrador. Anteriormente era ZDI-CAN-5100.
