PCI DSS testing failure

L0 Member

We are using SecurityMetrics to test for PCI compliance and have recently started receiving a failure based on TCP/IP Initial Sequence Number (ISN) Reuse Weakness (CVE-2002-1463) for the PaloAlto firewall (5.0.8).

I'm not sure how to remedy the problem within the firewall. There have been no rule changes that should have caused this to start to occur but we have updated the firewall from previous release.

It actually happened twice and I ended up reporting the findings as false positives on both occasions. I provided some documentation/information etc. The finding was corrected after an upgrade past the 9.1.13.
