- Check Point Firewall-1 PKI Web Service HTTP Header Remote Overflow


- Description


The Check Point Firewall-1 PKI Web Service, running by default on TCP
port 18264, is vulnerable to a remote overflow in the handling of very
long HTTP headers. This was discovered during a pen-test where the
client would not allow further analysis and would not provide the full
product/version info. Initial testing indicates the 'Authorization'
and 'Referer' headers were vulnerable.
