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/3144/info It has been reported that it is possible to cause a denial of service on a Windows NT system using the 'NT4ALL' tool. The DoS reportedly occurs after the system reboots while being set in 'special mode' using 'NT4ALL'. In order to exploit NT4ALL, a local user must reportedly have write permissions to the C:\winnt\system32\ directory. This is a non-default configuration. https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/21047.zip
