Hi,
I have just run a scan through my card service provider on my BT Business router and the following error message/vulnerability has been raised which has meant that my scan has failed:
TCP/IP SYN+FIN Packet Filtering Weakness
The remote host does not discard TCP SYN packets that have the FIN flag set.<br/><br/>Depending on the kind of firewall you are using, an attacker may use this flaw to bypass its rules.
It then suggests I contact BT for a patch.
Can anyone help with this please?
Cheers.
