A vulnerability has been reported in Community Builder Enhanced component for Joomla!, which can be exploited by malicious users to disclose sensitive information and to potentially compromise a vulnerable system.
Input passed via the "tabname" parameter to index.php (when "option" is set to "com_cbe", "task" is set to "userProfile", "user" is set, and "ajaxdirekt" is set to "true") is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal sequences and URL-encoded NULL bytes.
NOTE: This can further be exploited to execute arbitrary PHP code by e.g. uploading and including specially crafted image files.
The vulnerability is reported in version 1.4.8, 1.4.9, and 1.4.10. Prior versions may also be affected.
Solution: Update to version 1.4.11.
