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/333/info A vulnerability exists in the /usr/bin/X11/cdplayer application as shipped with SGI's IRIX operating system. By failing to shed root privileges, and creating arbitrary directories as root, cdplayer allows arbitrary users to gain root on the system. The -dbcdir option to cdplayer specifies the directory to store information kept by cdplayer. This can be used to create arbitrary directories. By creating a directory belonging to an account whose home directory does not exist, creating a .rhosts file in this directory, and chowning the rhosts file to the account being attacked, any user on the system can obtain root status. umask 000 cdplayer -dbcdir /usr/admin/ echo "+ +" > /usr/admin/.rhosts chown root.sys /usr/admin/.rhosts rsh localhost -l sysadm
