Some vulnerabilities have been discovered in BandSite CMS, which can be exploited by malicious people to conduct cross-site scripting and SQL Injection attacks or compromise a vulnerable system.

1) Input passed to the "max_file_size_purdy" parameter in adminpanel/includes/helpfiles/help_mp3.php, the "message_text" parameter in adminpanel/includes/mailinglist/sendemail.php, the "this_year" parameter in includes/footer.php, and to the "the_band" parameter in various files is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Successful exploitation requires that "register_globals" is enabled.

It has also been reported, that it is possible to disclose the full path to various scripts by requesting them directly.

2) Input passed to the "type" parameter in merchandise.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

3) Input passed via the "memid" parameter to includes/content/member_content.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

4) An error exists in the file upload functionality due to the "adminpanel/scripts/addphotos.php" script not properly checking file extensions. This can be exploited to upload files with arbitrary extensions and e.g. execute arbitrary PHP code.

The vulnerabilities are confirmed in version 1.1.4. Other versions may also be affected.
