RediShell – You’ve Got to Be Fucking Kidding Me

Oh, joy. Another Remote Code Execution (RCE) vulnerability. This time it’s in Redis, that little in-memory data store everyone loves because it’s “fast.” Apparently, some clowns have discovered a way to inject commands into Redis instances using Lua scripting – specifically, exploiting how modules are handled. They’re calling it “RediShell” like it’s clever. It isn’t.

Basically, if you haven’t properly secured your Redis deployments (and let’s be honest, most of you haven’t), attackers can upload malicious Lua modules that give them a shell on the server. This means complete compromise. Data theft, ransomware, botnet inclusion – the whole nine yards. It affects versions 7 and 8, so check your shit *now*.

The fix? Update to patched versions (7.0.12 or 8.0.7). And for fuck’s sake, disable module loading if you don’t need it! Seriously, why are you running features you aren’t using?! It’s like leaving your front door unlocked and then being surprised when someone walks in.

Dark Reading says this is actively exploited. So yeah, get patching before you’re cleaning up a mess. Don’t come crying to me when your data gets hosed because you were too lazy to apply a security update.

Anecdote: I once had to deal with a system admin who refused to patch a critical server because “it might break something.” It *was* already broken, thanks to a previous unpatched vulnerability. He learned the hard way that sometimes breaking things on your schedule is better than having them broken for you by some script kiddie. Honestly, people…
