It has the features you want from a BitTorrent client: encryption, a web interface, peer exchange, magnet links, DHT, ВµTP, UPnP and NAT-PMP port forwarding, webseed support, tracker editing, global and per-torrent speed limits, and more.

Ormandy said the vulnerability (CVE-2018-5702) was the 'first of a few remote code execution flaws in various popular torrent clients,' though he did not name the other torrent apps due to the 90-day disclosure timeline.ДЄ fix is expected to be released as soon as possible, a development official with Transmission told ArsTechnica, without specifying an actual date.About Transmission BTC - Torrent Downloader Transmission is a powerful yet extremely lightweight and fast BitTorrent client. Here's how the attack works:ДЄ user visits malicious site (), which has an iframe to a subdomain controlled by the attacker.The attacker configures their DNS server to respond alternately with 127.0.0.1 and 123.123.123.123 (an address controlled by the attacker) with a very low TTL.When the browser resolves to 123.123.123.123, it serves HTML that waits for the DNS entry to expire (or force it to terminate by flooding the cache with lookups), then it has permission to read and set headers. It does not work like that, but this is a common source of confusion.'ДЄttackers can exploit this loophole by simply creating a DNS name they're authorized to communicate with and then making it resolve to the vulnerable computer's localhost name.

'These users understand that services bound to localhost are only accessible to software running on the local machine and that their browser is running on the local machine-but somehow believe that accessing a website 'transfers' execution somewhere else. 'I regularly encounter users who do not accept that websites can access services on localhost or their intranet,' Ormandy wrote in a separate post, which includes the patch. The loophole resides in the fact that services installed on localhost can be manipulated to interact with third-party websites. Ormandy found that a hacking technique called the 'domain name system rebinding' attack could successfully exploit this implementation, allowing any malicious website that user visits to execute malicious code on user's computer remotely with the help of installed daemon service. The daemon installed on the user system then interacts with the server for downloading and uploading files through the browser using JSON RPC requests.

Transmission BitTorrent app works on server-client architecture, where users have to install a daemon service on their systems in order to access a web-based interface on their browsers locally.

Ormandy confirmed his exploit works on Chrome and Firefox on Windows and Linux (Fedora and Ubuntu) and believes that other browsers and platforms are also vulnerable to the attack. The PoC attack published by Ormandy exploits a specific Transmission function that lets users control the BitTorrent app with their web browser. Proof-of-Concept Exploit Made Publicly Available

I suspect they won't reply, but let's see,' Ormandy said in a public report published Tuesday.

'I'm finding it frustrating that the transmission developers are not responding on their private security list, I suggested moving this into the open so that distributions can apply the patch independently. However, in this case, the Project Zero researchers disclosed the vulnerability 50 days prior to the actual time limit because Transmission developers failed to apply a ready-made patch provided by the researchers over a month ago. Usually, Project Zero team discloses vulnerabilities either after 90 days of reporting them to the affected vendors or until the vendor has released a patch. The vulnerability has been uncovered by Google's Project Zero vulnerability reporting team, and one of its researchers Tavis Ormandy has also posted a proof-of-concept attack-just 40 days after the initial report. A critical vulnerability has been discovered in the widely used Transmission BitTorrent app that could allow hackers to remotely execute malicious code on BitTorrent users' computers and take control of them.
