SkaDate Lite version 2.0 suffers from an authenticated arbitrary PHP code execution vulnerability. This is caused due to the improper verification of uploaded files in '/admin/settings/user' script thru the 'avatar' and 'bigAvatar' POST parameters. This can be exploited to execute arbitrary PHP code by uploading a malicious PHP script file with '.php5' extension (to bypass the '.htaccess' block rule) that will be stored in '/ow_userfiles/plugins/base/avatars/' directory.
