Ilia Alshanetsky FUDForum 2.6.15

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.

FUDForum 2.6.15 with "Tree View" enabled, as used in other products such as phpgroupware and egroupware, allows remote attackers to read private posts via a modified mid parameter.

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.
