Cross-site scripting (XSS) vulnerability in install/forum_data/src/custom_fields.inc.t in FUDforum 3.0.4.1 and earlier, when registering a new user, allows remote attackers to inject arbitrary web script or HTML via a custom profile field to index.php. NOTE: some of these details are obtained from third party information.
SQL injection vulnerabilities in FUDforum before 2.2.0 allow remote attackers to perform unauthorized database operations via (1) report.php, (2) selmsg.php, and (3) showposts.php.
