DESCRIPTION:
Vrs-hCk has discovered a vulnerability in the RWCards component for
Joomla!, which can be exploited by malicious people to disclose
sensitive information.
Input passed to the "img" parameter in captcha/captcha_image.php is
not properly sanitised before being used. This can be exploited to
display arbitrary files via directory traversal attacks and
URL-encoded NULL bytes.
Successful exploitation requires that "magic_quotes_gpc" is
disabled.
The vulnerability is confirmed in version 3.0.11. Other versions may
also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
