TP4 insecurely loads pages with revoked/invalid security certificates



  • OS: OS X Yosemite 10.10.4 iOS 8.4 Browsers tested: Vivaldi 1.0.219.53 TP4 FAILED Opera 30.0.1835.125 PASSED Opera 12.16 (Ancient Presto engine) PASSED Firefox 39 PASSED Chrome 44.0.2403.125 FAILED Chrome for iOS 43.0.2357.61 FAILED Safari 8.0.7 (10600.7.12) FAILED Safari for iOS 8.4 (12H143) FAILED Summary: Both the deprecated, extremely old Opera 12 Presto browser and the modern Blink based Opera browser pass, as well as the latest version of Gecko based Firefox 39. Those browsers correctly reject web pages with broken certificates and warn their users. This is the safest default behavior. Test your own browser: https://revoked.grc.com Read more about Steve Gibson's Security Certificate Revocation Awareness Test: https://www.grc.com/revocation.htm It is alarming that Vivaldi (and most browsers) default behavior is to go ahead and load a potentially untrustworthy web page presenting an invalid security certificate, instead of displaying a warning page to the user. I urge the development team to take certificate revocation seriously and change the default behavior before the final release!

    Vivaldi tells me this:
    This site uses a weak security configuration (SHA-1 signatures), so your connection may not be private.

    The site test won't work right now because the sites certificate is revoked, due to network errors and attacks. Try it again in a few weeks maybe, when the certificate information has been updated.

    Hi,

    My testing just now indicates that both Vivaldi and Chrome 44 report the certificate as revoked.

    Please keep in mind that Chromium primarily does not go online to fetch revocation information, but regularly download a condensed list of revoked certs from Google, called CRLSets. There could be a slight delay in this process after installation. Additionally, AFAIK the list is not a complete list of all revoked certificates.

    Vivaldi is also configured to use OCSP for revocation checking.



  • https://revoked.grc.com/ is no longer showing as revoked.

    Please use current Vivaldi versions, TP4 is very old from 2015.
