A vulnerability has been discovered in the ccNewsletter component for Joomla, which can be exploited by malicious people to disclose potentially sensitive information.
Input passed to the "controller" parameter in index.php (when "option" is set to "com_ccnewsletter") is not properly sanitised before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and URL-encoded NULL bytes.
The vulnerability is confirmed in version 1.0.5. Other versions may also be affected.
Solution: Update to version 1.0.6.
Provided and/or discovered by: B-HUNT3|2 and AtT4CKxT3rR0r1ST
