|

This module exploits a vulnerability in TestLink version 1.9.3 or prior.
|
||||
This application has an upload feature that allows any authenticated
|
||||
user to upload arbitrary files to the '/upload_area/nodes_hierarchy/'
|
||||
directory with a randomized file name. The file name can be retrieved from
|
||||
the database using SQL injection.
