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/9778/info It has been reported that Squid Proxy may be prone to an unauthorized access vulnerability that may allow remote users to bypass access controls resulting in unauthorized access to attacker-specified resources. The vulnerability presents itself when a URI that is designed to access a specific location with a supplied username, contains '%00' characters. This sequence may be placed as part of the username value prior to the @ symbol in the malicious URI. Squid Proxy versions 2.0 to 2.5 STABLE4 are reported to be prone to this vulnerability. http://foo%[email protected]/
