20, it would have failed,вЂќ Duff told Threatpost.Дuff said exploitation of this vulnerability would be a challenge and likely be limited to a nation-state level of attack. вЂњIf he had not done this test between Sept. 10, meaning that pinning had not been enforced since. 3 and the regular Firefox release pins expired Sept. The Firefox ESR pins expired, instead, on Sept. Mozilla, however, did not set the expiration data to last until the next Firefox release, which is tomorrow, Duff said. These pins expire and the expiration dates are set, in this case, by Mozilla. Tor, which is built from the Firefox code base, suffered from MozillaвЂ™s decision to use a static certificate pin list and a HPKP (HTTP Public Key Pinning) pre-load list of pins with the browser. Duff wrote last week in a post to the Daily Dave mailing list that movrckвЂ™s attack against Tor should have failed and his malicious extension should not have loaded because of TorвЂ™s strict enforcement of certificate pinning. The twist is that movrckвЂ™s discovery was a bit serendipitous, researcher and former U.S. Forging or stealing a TLS certificate is the hard part, but it has been done before in 2011 when Iranian hackers compromised Dutch Certificate Authority DigiNotar and obtained valid wildcard certificates for Google, Mozilla, Yahoo and others. Movrck said that the attack could be pulled off for about $100,000, a cost well within the reach of a criminal operation or nation-state attacker.

The attacker would then be able to inject a malicious NoScript update that would be sent to a Tor browser, gaining remote code execution.

In explaining the exploit chain required, movrck said an attacker would have to run malicious exit nodes on the Tor network putting himself in man-in-the-middle position to intercept update traffic for addons. He said that a resourced attacker with the ability to steal or forge a TLS certificate for could put the entire Tor (and Firefox) ecosystem at risk to compromise. The vulnerability first saw light of day last week when a researcher who goes by the handle movrck published his disclosure. The flaw also affected the Tor Browser and was patched Friday by the Tor Project.

Each channel has different usages and updates frequency.Mozilla is expected tomorrow to patch a critical vulnerability in FirefoxвЂ™s automated update process for extensions that should put the wraps on a confusing set of twists surrounding this bug.
