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/11871/info Multiple remote vulnerabilities reportedly affect GNU wget. These issues are due to the application's failure to properly sanitize user-supplied input and to properly validate the presence of files before writing to them. The issues include: - a potential directory-traversal issue - an arbitrary file-overwriting vulnerability - a weakness caused by the application's failure to filter potentially malicious characters from server-supplied input. Via a malicious server, an attacker may exploit these issues to arbitrarily overwrite files within the current directory and potentially outside of it. This may let the attacker corrupt files, cause a denial of service, and possibly launch further attacks against the affected computer. Overwriting of files would take place with the privileges of the user that activates the vulnerable application. -- )^o-o^| jabber: [email protected] | .v K e-mail: jjminar FastMail FM ` - .' phone: +44(0)7981 738 696 \ __/Jan icq: 345 355 493 __|o|__Min?? irc: [email protected] #!/usr/bin/perl -W # wgettrap.poc -- A POC for the wget(1) directory traversal vulnerability # # Copyright 2004 Jan Min????
