Ilia Alshanetsky FUDForum 2.6.1

The Avatar upload feature in FUD Forum before 2.7.0 does not properly verify uploaded files, which allows remote attackers to execute arbitrary PHP code via a file with a .php extension that contains image data followed by PHP code.

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.
