SQL Injecting FlyFF MMO

[Seedlord]

I just read an article about SQL Injecting in Flyff. I never really played FlyFF but this seems pretty interesting.
I dont know if this is still possible, seems to be fixxed on the official servers, but on some (old) Pservers it might work.

Looooooool! who leaked that info, last 2 weeks I was doing this in some pservers and the offi.
No, it seems fixed in most pservers. It only worked on my v15 local server.

Lol at first i thought, who the heck digs out that kinda old stuff, then realizing it been posted not very long ago.

Still weird to see a documentation for something thats fixed on almost every server, specially those where it would actually be useful, taking apart those pinoy-ripoff servers lol....

You might be a little late to join the SQL injection squad haha, recently alot of stuff got patched up as some rude people had some fun on the xblubbs page, which apparently, 98% of server's are using, atleast in a variant.

Feel free to check out the fix for it, it might give you an idea how to perform it. It's probably going to work on fresh servers, and some pinoy ones which arent reading epvp lol

Main issue comes from this ****** code where unhandled packet will be sent directly to the database server.
=> g_dpDBClient.SendToServer( idFrom, lpMsg, dwMsgSize );

void CDPLoginSrvr::UserMessageHandler( LPDPMSG_GENERIC lpMsg, DWORD dwMsgSize, DPID idFrom )
{
	static size_t	nSize	= sizeof(DPID);
	CAr ar( (LPBYTE)lpMsg + nSize, dwMsgSize - nSize );		// Skip dpid

	if( dwMsgSize < 8 )		// INVALID PACKET
	{
		FLERROR_LOG( PROGRAM_NAME, _T( "PACKET//0" ) );
		return;
	}

	GETTYPE( ar );
	PACKET_HANDLER_FUNC pfn	=	GetHandler( dw );
	
	if( pfn )
	{
		( this->*( pfn ) )( ar, idFrom );
	}
	else
	{
		g_dpDBClient.SendToServer( idFrom, lpMsg, dwMsgSize );
	}

As a fix you can for example check the account_name the same way as for checking the player_name (IsInvalidName) in the function:

void CDbManager::CreatePlayer( CQuery *qry, LPDB_OVERLAPPED_PLUS lpDbOverlappedPlus )

	

	if( prj.IsInvalidName( lpDbOverlappedPlus->AccountInfo.szPlayer ) 
		|| prj.IsAllowedLetter( lpDbOverlappedPlus->AccountInfo.szPlayer ) == FALSE 
		|| prj.IsInvalidName(lpDbOverlappedPlus->AccountInfo.szAccount)
		|| prj.IsAllowedLetter(lpDbOverlappedPlus->AccountInfo.szAccount) == FALSE
		)
	{
		FreeRequest( lpDbOverlappedPlus );
		return;
	}

You check 2 time szPlayer, think you forgot to change the second one to szPassword.

Official is fix, they use different type of bindsparam.
One of the smartest thing they did in 10 years actually lol.

You can also use them to your v.15 sources, you just have to check the follow bindsparam & copy them :

	BOOL	BindParameterByte( SQLSMALLINT ParamType, SQLPOINTER ParameterValuePtr );

	BOOL	BindParameterShort( SQLSMALLINT ParamType, SQLPOINTER ParameterValuePtr );
	BOOL	BindParameterUShort( SQLSMALLINT ParamType, SQLPOINTER ParameterValuePtr );

	BOOL	BindParameterInt( SQLSMALLINT ParamType, SQLPOINTER ParameterValuePtr );
	BOOL	BindParameterUInt( SQLSMALLINT ParamType, SQLPOINTER ParameterValuePtr );

	BOOL	BindParameterInt64( SQLSMALLINT ParamType, SQLPOINTER ParameterValuePtr );
	BOOL	BindParameterUInt64( SQLSMALLINT ParamType, SQLPOINTER ParameterValuePtr );

	BOOL	BindParameterFloat( SQLSMALLINT ParamType, SQLPOINTER ParameterValuePtr );

	BOOL	BindParameterChar( SQLSMALLINT ParamType, SQLUINTEGER ColumnSize, SQLPOINTER ParameterValuePtr );
	BOOL	BindParameterVarChar( SQLSMALLINT ParamType, SQLUINTEGER ColumnSize, SQLPOINTER ParameterValuePtr );

Ah no nvm I derped yday, cookie was talking about how the login servers just passes to the DB the parameters are passed correctly just they aren't verified
