Is my admin commands script system secure/exploiter proof?

[Ethanthegrand14 (Ethanthegrand)]

For the past year I’ve been developing my own simple and secure admin system with many features.

I tried very hard to make this as exploit proof as possible while maintaining functionality. Hopefully I have succeeded in that.

Take a look!

I don’t understand what you mean by this? Are you implying that we use exploits to try and breach your admin panel? Or just review its code and give a rough estimation. If the second one then can you send it here rather than the file?

It’s an entire admin system. It’s not a single code snippet. There’s like 30+ scripts, modules, and not to mention all the local scripts for the widgets.

Just drag and drop the file into your studio window. it will be easier to view

Ah okay that’s much understandable lol.

Oh, I did know it would have multiple script but I meant it as just the exploit detection part. But it’s fine. I’ll let you know in a bit maybe.

There isn’t much actual exploit prevention. It’s the use of mostly server scripts and security checks on the remotes, but I can send the script that manages the remote events.

Even this script is hard to judge as the code is spread out through modules, you’re probably better off using the model file

[K4ttt_i (Kat)]

As for OP, I looked through the script you sent (I can’t for the model as I am on mobile and accessing my computer is currently IMPOSSIBLE) and it does seem fine I suppose? I do still think that exploiters could use the remote events as you aren’t really securing them as much? I might be wrong though…

[iop2319 (giantfecalmatterDEV)]

They can hook and bypass the security checks with certain DCSIE methods (Deep Cache Security Injection Exploit) which is still a problem even with Byfron. Exploiters using this technique can localize and write to every upvalue on the servers LuaU Virtual Machine .
