我们采用cyclic去确定输入点距离返回地址的偏移。 用cyclic填充两百个字符,然后用cyclic -l得到偏移。 因为这是静态链接,因此我们可以很轻松的去里面拿到我们想要的/bin/sh参数和system函数。 事实上我们没有办法搜到system函数,但是猜测一下,system会调用/bin/sh,因此我们先去找一下/bin/sh 如果你的IDA没有出现上...

`cyclic`命令可以生成特定格式的循环字符串,通过观察程序崩溃时的内存地址,利用`cyclic -l`命令可以计算出溢出的偏移量。 17. 用法点`cyclic_find`命令用于根据程序崩溃时的地址查找对应的循环模式偏移量,简化偏移量计算过程。 用法详解:当程序因缓冲区溢出崩溃后,`cyclic_find`命令可以根据崩溃地址快速找到对应的循环...
