x server detection vulnerability

[Praveen Kumar]

Team,

 

During my last internal vulnerability assessment I found few vulnerabilities related to "X Server" which are " 'X Server Detection', 'X11 Server Unauthenticated Access' & 'X Server Unauthenticated Access: Screenshot' " and the recomentation provided by Nessus is "Restrict access to this port by using the 'xhost' command. If the X client/server facility is not used, disable TCP connections to the X server entirely" as the ports identified with this vulnerabilities are (6000 & 6001) which are already blocked from the network side. however we are still getting this .

 

Please provide your valuable suggestions to fix this vulnerability.

 

Regards,

Praveen D Kumar.
