Description:
Alberto Trivero has reported some vulnerabilities and a security issue in Ultimate PHP Board, which can be exploited by malicious people to conduct cross-site scripting attacks and disclose sensitive information.

1) Some input isn't properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of a vulnerable site.

Examples:
http://[host]/login.php?ref=[code]
http://[host]/viewtopic.php?id=[code]
http://[host]/viewtopic.php?id=1&t_id=1&page=[code]
http://[host]/profile.php?action=get&id=[code]
http://[host]/newpost.php?id=1&t=1&t_id=[code]
http://[host]/newpost.php?id=[code]
http://[host]/email.php?id=[code]
http://[host]/icq.php?action=get&id=[code]
http://[host]/upb/aol.php?action=get&id=[code]
http://[host]/upb/getpass.php?ref=[code]
http://[host]/search.php?step=3&sText=[code]

2) User credentials are stored in the "db" database directory inside the web root, which may allow disclosure of the usernames and encrypted passwords.

NOTE: This does not affect installations with enabled support for ".htaccess" files. The encrypted passwords can easily be decrypted due to a weak encryption method.

It is also possible to disclose the full path to certain scripts by accessing them with some invalid input.

The vulnerabilities and the security issue have been reported in version 1.9.6 GOLD and prior.
