TLS 1.0 and 1.1 Upcoming End of Support Announced

Early last week saw a coordinated effort from almost major browser vendor to follow the guidelines of the PCI-DSS standard and to end support for TLS 1.0 and 1.1

Why should this change be considered relevant?
Each of the browser vendors have worked together to create a definite timeline (starting in 2020 and complete by July 2020) for the end of support of these now obsolete security protocols. TLS 1.0 is almost 20 years old and is no longer PCI-DSS compliant.  Separately TLS 1.1 is more than 10 years old. They both contain known vulnerabilities e.g. BEAST (an attack), DROWN or FREAK (both downgrade attacks) etc. use insecure hash functions (e.g. MD5 and SHA-1) and receive very little use today:

0.4% from Apple Safari (<0.36% for all connections) (Source: WebKit)

0.5% for Google Chrome (Source: Google)

1.2% of Firefox Beta 62 during the time August-September 2018 (Source: Mozilla)

0.72% for Microsoft Edge (Source: Microsoft)

More modern standard e.g. TLS 1.2 offers improved performance when used with HTTP/2 and are PCI-DSS compliant. Moreover, it doesn’t suffer from all of the vulnerabilities affecting prior versions and includes stronger alternatives to older hash functions e.g. ECDHE_RSA_WITH_AES_128_GCM_SHA256 .

What does the future hold?
Following the recent deprecation of any standard of TLS older than 1.2 on the 30th of June this year due to the mandate set by the PCI Security Standard Council has steadily seen the increase of the recently ratified TLS 1.3 (in April 2018) but defined within (Request for Comments) RFC 8446 in August. This is in part due to a change by Mozilla to Firefox in April and the adoption of the newest standard by some popular websites e.g.:

Google’s Gmail (although the newer standard isn’t always enabled)

https://www.bleepingcomputer.com/

https://www.securityweek.com/

https://nakedsecurity.sophos.com

https://www.theregister.co.uk/

https://www.wordpress.com (which also includes this blog you are reading!)

The OpenSSL Foundation added full TLS 1.3 support to their popular cryptographic library OpenSSL with the release of version 1.1.1 in September 2018. OpenSSL are further driving adoption of the newest standard by ending support for the current long term support (LTS) version 1.0.2 by the end of 2019 (with it only receiving security updates after the 31st December 2018).

The increase in traffic is best illustrated by Mozilla showing approaching 6% usage for Firefox Beta 62 during the time August-September 2018. Such an increase is really good news for the security of the Internet specifically any online service that requests personal information and e-commerce websites in particular.

For more information on which web browsers support TLS 1.3, please see this link with a table from Salesforce illustrating browser support for TLS 1.2 here.

Thank you.

July 2018 Update Summary

Earlier this month, Microsoft made available their usual monthly security updates. This month 53 vulnerabilities more formally known as CVEs (defined) were resolved.

Among these updates are further updates for Spectre NG vulnerabilities (also known as Speculative Store Bypass vulnerabilities) making them available for Windows Server 2008, Windows Server 2012, Windows 8.1, and Windows Server 2012 R2 in addition to last month’s updates. The vulnerability known as Lazy Floating Point (FP) was also addressed this month. Finally the Spectre 1.1. and Spectre 1.2 vulnerabilities will be discussed in a separate blog post.

This month’s Microsoft updates have a long list of Known Issues detailed in the knowledge base (KB) articles listed at the abovel ink (due to the length I won’t reproduce it here). At the time of writing some of these issues have begun to be addressed by further updates (Windows 7, Windows 8.1 and Windows 10) released by Microsoft. Others relating to the .Net Framework should be addressed soon.

====================

This month also saw Adobe release an update (priority 2) for Adobe Acrobat DC and Reader DC which addresses 104x CVEs alone. The remaining updates made available this month were:

Adobe Connect (priority 2, 3x CVEs)

Adobe Experience Manager (priority 2, 3x CVEs)

Adobe Flash (priority 2, 2x CVEs)

For Flash, updates for Google Chrome (not a separate update but via its component updater), Microsoft Edge and Internet Explorer were made available. As always if you use any of the above Adobe software, please update it as soon as possible especially in the case of Flash and Acrobat DC/Reader DC.

These mitigations (listed at the end of his in-depth discussion) will better defend your system(s) against a variant of this vulnerability which still remains relatively easy for an attacker to exploit.

Thank you.

Pwn2Own 2018 Results

Earlier this month the annual Pwn2Own white hat (defined) hacking contest took place, shortened from 3 days to 2 days.

This year’s competition was also impacted by a recent regulatory change meaning that Chinese participants were unable to attend. This is unfortunate since previous yeas competitions have been excellent and this had a real impact on the success of this year’s competition; perhaps next years will be better? Further details of the regulatory change are detailed here.

The following products were successfully exploited this year resulting in USD$267k being awarded. Exploits which could not be completed in the allocated time of 30 minutes were also purchased; which is fair in my opinion since they could still be a threat and the researchers more than deserve the credit for the time and effort they invest.

Similar to previous years; kernel (defined) exploits were used each time to exploit the web browsers due to the sandboxing (defined) technology used to security harden them.

As noted in this article (and my previous blog posts) kernels are becoming even more complex and can easily consist of millions of lines of code. My previous advice of static analysis/auditing/fuzzing (defined here and here) still applies. These won’t detect every vulnerability but will significantly reduce them. As before writing more secure code using the development practices discussed in last year’s Pwn2Own post will reduce the vulnerability count even further; both now into the future.

Just like last year Mozilla updated Firefox very quickly; this time in less than a day to version 59.0.1 and 52.7.2 ESR.

I’ll update this post as the vulnerabilities disclosed during the contest are addressed. The full list of products exploited is provided below. Thank you.
