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.
Exploit information
Exploit Database EDB-ID : 20593

There exists a serious vulnerability in FreeBSD's implementation of packet filtering for IPv4 and IPv6.
The vulnerability exists in situations where a filtering rule permits packets through if they are part of an established connection.
It is possible for packets that are not part of an established connection to be allowed through. These packets must have the ECE flag set, which is in the TCP reserved options field.
Exploitation of this vulnerability may allow for unauthorized remote access to otherwise protected services.
