Description


rgod has discovered a vulnerability in pppBLOG, which can be exploited by malicious people to disclose sensitive information.

Input passed to the "files[0]" parameter in randompic.php isn't properly verified, before it is used in a "readfile()" call. This can be exploited to disclose the content of arbitrary files via directory traversal attacks.

Successful exploitation requires that "register_globals" is enabled.

The vulnerability has been confirmed in version 0.3.8. Other versions may also be affected.


Solution:
Edit the source code to ensure that input is properly verified.
