SQL injection vulnerability in submit.php in PHP-Fusion 6.01.14 and 6.00.307, when magic_quotes_gpc is disabled and the database table prefix is known, allows remote authenticated users to execute arbitrary SQL commands via the submit_info[] parameter in a link submission action. NOTE: it was later reported that 7.00.2 is also affected.

Multiple cross-site scripting (XSS) vulnerabilities in submit.php in PHP-Fusion before 6.01.3 allow remote attackers to inject arbitrary web script or HTML by using edit_profile.php to upload a (1) avatar or (2) forum image attachment that has a .gif or .jpg extension, and begins with a GIF header followed by JavaScript code, which is executed by Internet Explorer.

SQL injection vulnerability in messages.php in PHP-Fusion 6.00.307 and earlier allows remote authenticated users to execute arbitrary SQL commands via the srch_where parameter.

PHP-Fusion 6.00.306 and earlier, running under Apache HTTP Server 1.3.27 and PHP 4.3.3, allows remote authenticated users to upload files of arbitrary types using a filename that contains two or more extensions that ends in an assumed-valid extension such as .gif, which bypasses the validation, as demonstrated by uploading then executing an avatar file that ends in ".php.gif" and contains PHP code in EXIF metadata.

Multiple directory traversal vulnerabilities in PHP-Fusion 6.00.306 allow remote attackers to include and execute arbitrary local files via (1) a .. (dot dot) in the settings[locale] parameter in infusions/last_seen_users_panel/last_seen_users_panel.php, and (2) a .. (dot dot) in the localeset parameter in setup.php. NOTE: the vendor states that this issue might exist due to problems in third party local files.

Cross-site scripting (XSS) vulnerability in PHP-Fusion before 6.00.304 allows remote attackers to inject arbitrary web script or HTML via the (1) shout_name field in shoutbox_panel.php and the (2) comments field in comments_include.php.

SQL injection vulnerability in PHP-Fusion 6.00.200 through 6.00.300 allows remote attackers to execute arbitrary SQL commands via the ratings parameter in multiple scripts, such as ratings_include.php.

Multiple cross-site scripting (XSS) vulnerabilities in PHP-Fusion 6.00.200 through 6.00.300 allow remote attackers to inject arbitrary web script or HTML via (1) the sortby parameter in members.php and (2) IMG tags.
