If an attacker knows specifically what files they are looking for, this same vulnerability can be used to extract that information.

Alternatively, you can use Impacket to relay that hash to another machine on the network, achieving remote code execution.

This can be cracked to clear-text using tools like Hashcat. If using Impacket, you will now have the NetNTLM challenge/response of the user running Vuze. When that happens, either the netcat listener or the Impacket SMB server will receive the connection. New Host 192.168.1.100, Service Type: urn:schemas-upnp-org:device:InternetGatewayDevice:1 evil-ssdp will display messages like the following: From a Windows host on the same network, simply restart Vuze. Sudo python examples/smbserver.py smb /tmp/smb/ДЈ.

Or use Impacket to listen and extract the NetNTLM challenge/response as follows: From the same Linux host, either launch a simple netcat listener like this: Execute the evil-ssdp tool as follows from a Linux host:Д®ssdp.py eth0 -t xxe-smb # instructs tool to use the 'xxe' template for zero-day huntingДў. This vulnerability can be easily validated using the ().ДЎ.

This is a common attack method inside a Windows domain, where compromising an account can assist with moving laterally through the network. # POC 1: Capcturing NetNTLM Challenge/Response The unexpected behaviour here is the ability to provide the `ENTITY` tags, forcing Vuze to automatically access file paths and HTTP URLs.

This is used for verification purposes while testing the vulnerability. Accesses an HTTP server at the $localIp variable. This allows us to collect or relay the NetNTLM challenge/response.Дў. Accesses the SMB share running at the $smbServer variable. When Vuze parses this, it does two things:ДЎ. The POC used to prove this vulnerability (POC 1 below) contained the following XML content: This is expected behaviour for SSDP/UPNP.Д«y hosting a specially crafted XML file at that location, we can force Vuze to do several things.

Vuze will automatically access the Device Descriptor over HTTP, parsing the XML content. When we do this, we provide the location of an XML file containing more information about our device. We can reply to that UDP multicast directly on the same port that the request initiated from, informing this client that we have a shared device. This is the first step in finding and adding Universal Plug and Play (UPNP) devices. The discovery process is handled by Simple Service Discovery Protocol (SSDP), which sends a UDP multicast out to 239.255.255.250 on port 1900. Vuze, like many other media servers, will attempt to discover other devices on a local network. Vuze version affected: Tested on 5.7.6.0 (current as of July 2018).

Impact: Information disclosure up to code executionДЄffected component: Vuze Bittorrent Client's SSDP discovery / XML parsing Multiple attempts to contact Vuze team resulted in no replies. Initiate SMB connections to relay NetNTLM challenge/response and achieve Remote Command Execution in Windows domains.Д®xploitation can be demonstrated using evil-ssdp (). Initiate SMB connections to capture NetNTLM challenge/response and crack to clear-text password. Access arbitrary files from the filesystem with the same permission as the user account running Vuze. Unauthenticated attackers on the same LAN can use this vulnerability to: The XML parsing engine for Vuze Bittorrent Client's SSDP/UPNP functionality is vulnerable to an XML External Entity Processing (XXE) attack.
