[Problema] Caidas consecutivas - nilesk - 24.01.2015
Buenas tardes, primero que nada este es mi problema: alguien al parecer ingresa a mi servidor y empieza a hacerse el "hacker" poniendo porquerias en el chat, despues, sucede esto:

La caнda es por el crash, CrashDetect te facilita diciйndote el error cual estб en la callback OnPlayerExitedMenu. el error creo que es por el bug en la funciуn HideMenuForPlayer (https://sampwiki.blast.hk/wiki/HideMenuForPlayer) pero si gustas podrнas mostrarnos el cуdigo de ahн? no creo que sea un hacker, es un lammer (si es que alguien lo hace conscientemente). Posiblemente conoce el filterscript que estбs usando y conoce tal vulnerabilidad.

Este es el codigo del ladmin
Код:
public OnPlayerExitedMenu(playerid)
{
new Menu:Current = GetPlayerMenu(playerid);
HideMenuForPlayer(Current,playerid);
return TogglePlayerControllable(playerid,true);
}

Sн, el problema es por el "bug" de la funciуn. Antes de utilizarla habнa que verificar si el que saliу del menъ estaba en uno.
pawn Код:
public OnPlayerExitedMenu(playerid)
{
new
Menu:Current;
if(!IsPlayerConnected(playerid) || (Current = GetPlayerMenu(playerid)) == INVALID_MENU)
return 0;
HideMenuForPlayer(Current,playerid);
TogglePlayerControllable(playerid, true);
return 1;
}

Es por el tag,
pawn Код:
public OnPlayerExitedMenu(playerid)
{
new
Menu:Current = GetPlayerMenu(playerid);
if(!IsPlayerConnected(playerid) || _:Current == INVALID_MENU)
return 0;
HideMenuForPlayer(Current,playerid);
TogglePlayerControllable(playerid, true);
return 1;
}
Re: [Problema] Caidas consecutivas - nilesk - 24.01.2015
Код:
Menu:Current = INVALID_MENU;

Cambiar esto:
pawn Код:
#define USE_MENUS
pawn Код:
//#define USE_MENUS
La vulnerabilidad se encuentra en HideMenuForPlayer, al enviar un ID de menъ invбlido. La IP en el log es de Alemania, y siendo su servidor en el idioma espaсol; es casi seguro que se trate de un "ataque" y no de un usuario que explotу dicha vulnerabilidad de casualidad (cosa que pasa en algunos casos).
Suerte
