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.

source: https://www.securityfocus.com/bid/2551/info PIX is an enterprise firewall engineered and maintained by Cisco Systems. It is designed to provide robust features and multiple methods of access control and filtering. A problem with the PIX could allow a denial of service. PIX firewalls using TACACS+ are vulnerable to a resource starvation attack which results in a denial of service. Upon receiving multiple requests for TACACS+ authentication from an unauthorized user, the firewalls resources can be exhausted. This causes the firewall to crash, requiring power cycling to resume regular service. This makes it possible for a user from either the public or private side of the PIX to crash the firewall, and deny service to legitimate users. All PIX Firewalls having configuration lines beginning with the following line are affected: pixfirewall# aaa authentication Any configurations not including aaa authentication are not affected. while (true); do (wget http://external.system 2>/dev/null &); done
