Bug vulnerability class | Configuration |
Bug description | The target host seems to be running an URCS server. This Unmanarc Remote Control Server could be used as a remote control backdoor which may allow an intruder to gain access to files on the remote system. If this program was not installed by the administrator or any user, this may indicate the compromise of the host. An attacker may use it to steal files, passwords, or redirect ports on the remote system to launch other attacks. |
Bug solution | The server should be deactivated or de-installed if not necessary. Try to prevent unwanted connection attempts by filtering traffic with firewalling. The default port for the URCS Server is tcp/3360 and for the Client is tcp/1980. See http://www.rapter.net/jm5.htm for further details. |
