TCP/IP SYN+FIN Packet Filtering Weakness
« on: September 11, 2017, 10:01:54 AM »
I ran a PCI Vul. Scan on my office network and got this Vulnerability. 
I believe its telling me to update my Routers firmware (which is the only device on my network that has a Firewall, other than PC's)

I re-ran the scan and it still failed, how can I get this to pass??

Threat:
It may be possible to bypass firewall rules.
