以 82.坐标修正数据包的处理与模拟 它的代码为基础进行修改

上一个内容里实现了无限水下游、模拟1F数据包（可以实现自动移动刷新我们的客户端画面），本次就来分析一下游戏瞬移漏洞的这个事情。

首先游戏瞬移漏洞是怎样产生的？第一种服务端是弱服务端，服务端没有校验客户端发什么就是什么，第二种在设计逻辑上面没有问题，但是逻辑给它岔开了用，这中岔开了用出现的问题很可能之前就没有考虑过，有的只做开发没有做安全，它不知道还可以这样玩，然后我这样玩逻辑就出现问题了，比如titan这游戏的数据包消息在NetClient类里把它还原成了函数比如OnMoveStop、OnMoveJump、OnMoveWJump这些还有在水下走路，这些东西岔开来用，就有可能找到它逻辑上的漏洞，就是它以前没相关它还会岔开来用，比如先OnMoveStop更新坐标然后OnMoveWalk向前走然后停下来OnMoveStop，这也就实现了走了，之前也这样欺骗的服务端实现了跟随，但也可以这样先OnMoveWalk然后OnMoveJump最后OnMoveStop，就是岔开了用以后，它的逻辑处不过来或者它本来的逻辑设定的就造成瞬移，但这种情况要大量的去测，也比较麻烦，这种的相对来说是比较低级的错误，犯的人也不是很多，所以成功率不是特别高，然后第三种是跟技能或者某些活动或者传送点有关，这种属于功能性的漏洞，这种相对来讲也不好搞，然后

第四种：

如下图，代码逻辑没有问题，但是进行 0 / 0之后float的值就出现问题了，然后就导致坐标设置成功，0/0是一个无效值，int类型会有检查而浮点数没有检查

它的结果是nan，nan==nan这样的比较结果是false，并不是true，nan与任何数字作比较都是false，只有 nan!=nan这样才会是true，这就导致了可以成功设置坐标，这是一个冷门的问题有的人不知道，就会出现漏洞

修复方式，加上一个浮点数最大值的判断就可以了，很多软件都会有这个漏洞，这种漏洞是很危险的，如果涉及到了金钱，这将是灾难，这个东西很危险，不要乱用，如果乱用出了事我不负责的

代码：

java代码解决方式，调用Double类的isNaN方法

class Untitled {public static void main(String[] args) {double d = Double.NaN;System.out.println(Double.isNaN(d));}
}

下方是c++代码

#include <iostream>float NextX, NextY;
void Init() {float i = 1;i--;NextX = i / i;NextY = i / i;
}float 人物x坐标, 人物y坐标, 移动速度 = 5.0f;bool 检测坐标是否合格(float 坐标, float 移动大小) {if (坐标 <= DBL_MAX || 坐标 >= -DBL_MAX) {return  (坐标 > 移动大小);}return true;}void 移动(float xNext, float yNext) {// 为了防止负数这里求绝对值float xDis = fabs(xNext - 人物x坐标);float yDis = fabs(xNext - 人物y坐标);if (检测坐标是否合格(xDis, 移动速度)) {std::cout << "  x坐标不合格，回弹"<<std::endl;return;}if (检测坐标是否合格(yDis, 移动速度)) {std::cout << "  y坐标不合格，回弹" << std::endl;return;}人物x坐标 = xNext;人物y坐标 = yNext;
}int main()
{Init();int* i = (int*)&NextX;std::cout << "   " << std::hex << i[0] << std::endl;移动(NextX, NextY);移动(10000, 10000);移动(5, 5);std::cout << "  x坐标：" << 人物x坐标 << "y坐标：" << 人物y坐标 << std::endl;
}

效果图：瞬移的位置没有地图所以没法走，但是也可以看出移动之后没有被回弹
