|
|
This module exploits a vulnerability found in WebPageTest's Upload Feature. By
|
|
default, the resultimage.php file does not verify the user-supplied item before
|
|
saving it to disk, and then places this item in the web directory accessable by
|
|
remote users. This flaw can be abused to gain remote code execution.
