PM Flooder Kick Hack

[Evor 72]

 

 

 

You didn't have to give the actual link to this kick hack.. now i have to make lib for 34k coz kids are playing around^

 

Having the information public is the fastest way to get people to take action against it and the fix is in the thread. If you're able to create libs then it should be no problem for you

 

Also having the hack we could test if the c++ fix works

 

 

 

give me the hack for test in my server? Thank you

only for testing purposes only and i don't know this works because i didn't use it

 

While reading source, i think that, it is an older version of kick hack, because of using WHISPER instead of MESSENGER (friend adding.).

Regards..

error in compile:

 

messenger_manager.cpp: In member function 'bool MessengerManager::AuthToAdd(const std::string&, const std::string&, bool)':

messenger_manager.cpp:153: error: return-statement with no value, in function returning 'int'

gmake: *** [OBJDIR/messenger_manager.o] Error 1

gmake: *** Waiting for unfinished jobs....

 

you're returning a wrong value, please put here the line 153 of messenger_manager.cpp.

Hi everyone,

Maybe just in my country, but it looks so many people started using this annoying PM flooder which cause a buffer overflow in the target client. It can be fixed easily on server-side, so let's do it:

Add these functions as public to char.h:

    void ClearPMCounter(void)       { m_iPMCounter = 0;      } 
    void IncreasePMCounter(void)    { m_iPMCounter++;        }
    void SetLastPMPulse(void);
    int  GetPMCounter(void)   const { return m_iPMCounter;   }
    int  GetLastPMPulse(void) const { return m_iLastPMPulse; }
    

Add these to char.h too, but as protected:

int m_iLastPMPulse;
int m_iPMCounter;
    

Add this function to char.cpp:

void CHARACTER::SetLastPMPulse(void)
{
      m_iLastPMPulse = thecore_pulse() + 25;
}

Still in char.cpp search for the Initialize and add these to the function:

m_iLastPMPulse = 0;
m_iPMCounter = 0;

Now navigate to the Whisper function in input_main.cpp and add this after the iExtraLen variable checking at the top:

if (ch->GetLastPMPulse() < thecore_pulse())
     ch->ClearPMCounter();
     
if (ch->GetPMCounter() > 3 && ch->GetLastPMPulse() > thecore_pulse())
{
   ch->GetDesc()->SetPhase(PHASE_CLOSE);
   return -1;
} 

Search for this still in the Whisper function:

if (pkChr == ch)
    return (iExtraLen);
    

Add these after that:

ch->IncreasePMCounter();
ch->SetLastPMPulse();
    

 

Can you put there files with thease functions allrdy implemented please... ?

THNX !

Fix for the newly released lagger/kicker:
 
Replace the ACMD(do_messenger_auth) method with this:

	if (ch->GetArena())
	{
		ch->ChatPacket(CHAT_TYPE_INFO, LC_TEXT("´ë·ĂŔ忡Ľ­ »çżëÇĎ˝Ç Ľö ľř˝Ŕ´Ď´Ů."));
		return;
	}

	char arg1[256], arg2[256];
	two_arguments(argument, arg1, sizeof(arg1), arg2, sizeof(arg2));

	if (!*arg1 || !*arg2)
		return;

	char answer = LOWER(*arg1);

	if (!MessengerManager::instance().AuthToAdd(ch->GetName(), arg2, answer == 'y' ? false : true))
		return;

	if (answer != 'y')
	{
		LPCHARACTER tch = CHARACTER_MANAGER::instance().FindPC(arg2);

		if (tch)
			tch->ChatPacket(CHAT_TYPE_INFO, LC_TEXT("%s ´ÔŔ¸·Î şÎĹÍ ÄŁ±¸ µî·ĎŔ» °ĹşÎ ´çÇß˝Ŕ´Ď´Ů."), ch->GetName());
	}

In messenger_manager.cpp replace the AuthToAdd method with this :

bool MessengerManager::AuthToAdd(MessengerManager::keyA account, MessengerManager::keyA companion, bool bDeny)
{
	DWORD dw1 = GetCRC32(companion.c_str(), companion.length());
	DWORD dw2 = GetCRC32(account.c_str(), account.length());

	char buf[64];
	snprintf(buf, sizeof(buf), "%u:%u", dw1, dw2);
	DWORD dwComplex = GetCRC32(buf, strlen(buf));

	if (m_set_requestToAdd.find(dwComplex) == m_set_requestToAdd.end())
	{
		sys_log(0, "MessengerManager::AuthToAdd : request not exist %s -> %s", companion.c_str(), account.c_str());
		return false;
	}

	m_set_requestToAdd.erase(dwComplex);

	if (!bDeny)
	{
		AddToList(companion, account);
		AddToList(account, companion);
	}

	return true;
}

In messenger_manager.h replace this:

void	AuthToAdd(keyA account, keyA companion, bool bDeny);

With this:

bool	AuthToAdd(keyA account, keyA companion, bool bDeny);

 

 

not work this annoying

When I accept duel from anyoneI get disconnected.
