Hi fellows. got this   Qid 34020

Title :

UDP Source Port Pass Firewall

 

Threat:

Your firewall policy seems to allow UDP packets with a specific source port (for example, port 53) to pass through while it blocks UDP packets to the same destination ports but with a random source port.

In the Result section, the service lists up to 16 such destination ports that can be reached by the UDP probes with a source port of 53. Note that in a default scan, we have only used port 53 as the source port. It is possible that the firewall also allows UDP packets with other well-known ports as source ports to go through.

 

 

please suggest any remedy/fixture  for this . this is 3750E platform
