If you use Mambo CMS for a website and haven’t updated recently, now might be the time to consider upgrading and patching.
This post talks about a vulnerability that has been found in the server. I just had first-hand experience of someone hacking one of my sites that uses Mambo. It seems that the security hole allows someone to get access to and overwrite the configuration.php file with their own HTML content, and have this page displayed instead of the Mambo-based site.
This is the first issue that I’ve had with Mambo up until this point.
