Official description

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.
