Firewall-1 does not properly filter script tags, which allows remote attackers to bypass the "Strip Script Tags" restriction by including an extra < in front of the SCRIPT tag.

EPSS
EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.
EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Firewall-1 includes the ability to alter script tags in HTML pages before passing them to the client's browser. This alteration invalidates the tag, rendering the script unexecutable by the browser. In version 3, this function can be bypassed by adding an extra opening angle bracket. The tag will be left unmodified, and the browser will be able to execute the contained script. Hostile script could lead to a remote compromise of the client system.
Firewall-1 version 4 will alter the tag as expected.
