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/1602/info A vulnerability exists in HP-UX, from Hewlett Packard, under certain configurations. Version 11.0 is confirmed to have this problem; other versions may also be susceptible. If the CLEAR_TMP option in /etc/rc.config.d is set to 1, meaning enabled, it is possible for a local user to create a symbolic link in /tmp that will be followed prior to being removed. This will allow the local user to overwrite any file upon reboot. The /sbin/rc2.d/S008net.init file, and /sbin/rc2.d/S204clean_tmps file are run upon reboot. The net.init is run first. (Lower number S scripts are run first). In the net.init file, a temporary file, /tmp/stcp.conf, is use. This file is blindly written to, and is removed by the clean_tmps script. A local user can simply create this file as a symbolic link to any file, and cause the net.init script to overwrite its contents upon reboot. ln -sf /VULNERABLE /tmp/stcp.conf and reboot.
