Oh, Joy. Another CMS Vulnerability.

Right, so some “researchers” (read: people who get paid to find obvious holes) have discovered a goddamn exploit chain in Sitecore. Because *of course* they did. It’s an unholy mess involving cache poisoning – meaning someone can shove garbage into the system’s memory – and then leverage that to achieve Remote Code Execution (RCE). Basically, they get to run whatever commands they want on your server. Fantastic.

The initial vulnerability is in how Sitecore handles certain requests, allowing attackers to inject malicious data into the cache. Then, because security is apparently optional these days, this poisoned cache can be used to execute code. It’s a two-step process for maximum annoyance and server compromise. They’re saying versions 10.2 and earlier are screwed, but honestly, if you’re still running that ancient crap, you deserve whatever you get.

Patches are available (surprise!), so update your systems *immediately* unless you enjoy cleaning up digital wreckage. And for the love of all that is holy, properly configure your Sitecore instances and monitor for suspicious activity. Don’t be a moron.

Honestly, this whole thing just proves that if you build something complicated enough, someone will find a way to break it. And then write an article about how clever they are for finding the inevitable flaws. It’s exhausting.

Speaking of poorly secured systems, I once had to deal with a company whose entire website was running on a PHP version so old it still supported Internet Explorer 6. They were shocked – *shocked* – when their database got pwned. Some people just ask for trouble. Don’t be those people.
