|
|
This module exploits a vulnerability found in Lotus CMS 3.0's Router()
|
|
function. This is done by embedding PHP code in the 'page' parameter,
|
|
which will be passed to a eval call, therefore allowing remote code execution.
|
|
|
|
The module can either automatically pick up a 'page' parameter from the
|
|
default page, or manually specify one in the URI option. To use the automatic
|
|
method, please supply the URI with just a directory path, for example: "/lcms/".
|
|
To manually configure one, you may do: "/lcms/somepath/index.php?page=index"
|
