Cross-site scripting (XSS) vulnerability in Vz Scripts ADP Forum 2.0.3 and earlier allows remote attackers to inject arbitrary web script or HTML via the Subject field (possibly messaggio parameter) when posting a new message in post.php.

ADP Forum 2.0 through 2.0.3 stores sensitive information in plaintext files under the web document root with insufficient access control, which allows remote attackers to obtain user credentials via requests to the forum/users directory.
