July 2016 scan results

This month the scan has a bit more information.

I’ve added special probes to detect whether the server is intolerant to specific types of Client Hello messages.

While support for TLSv1.2 is still not universal (being just under 90%), tolerance to Client Hello messages advertising support for TLSv1.2 is essentially full, with just 67 servers being detected as intolerant to such messages.

Support for more uncommon messages is much worse though, clients sending their maximum supported version set to TLSv1.2 can expect 1.3% of servers rejecting their connections. Higher protocol versions like TLSv1.4 have a rate of rejection on around 2.45%, for very high protocol versions it rises to 3.295% for SSL 3.254 (that would be TLSv1.253).

Clients sending Client Hello with a lot of options or extensions can expect even more intolerance. Sending multiple key shares (from TLSv1.3 draft), most of defined extensions and couple hundred ciphersuites can expect their connections rejected by over 7% of servers. In general intolerance for very big Client Hello messages, like 16KiB and 24KiB large, is respectively at 23.7% and a whopping 89.5%!

If fixing this will follow similar deployment rates as TLSv1.2 or RC4 deprecation, it doesn’t look like we will be able to deploy most Post Quantum key exchanges any time soon…

Besides that, there were no major changes, just continuation of long established trends, so I won’t be doing full analysis for this month too.

Scan performed between 20th of July and 17th of August 2016

November 2014 results – intolerancies

This time around, I have extended the scanning script to also include tests checking whatever servers are tolerant to specific settings inside client hello messages. The scan itself also gained a fallback mode in case the regular scan (used up until now for all data collection) haven’t detected any ciphers to be supported by server or server appearing to support just SSLv2. Another additions include scan for supported curves for ECDHE key exchange, key signature algorithm for TLSv1.2 ECDHE and DHE key exchange, secure renegotiation support and compression.

Protocol versions

While I have provided some results for intolerance of specific settings in the Halloween special, scan of the full Alexa top 1 million proved to be much more complex and harder to pin down in just few lines. I’m afraid I won’t be able to tell much about the bugs the servers seem to be showing until I develop tests for specific bugs rather than current probing with very generic (and rather standard) client hello messages.

That being said, general statistics look like this: about 4.8% of servers refused connection that started with a big full featured TLSv1.2 client hello, that includes about 0.1% of servers that are strictly TLSv1.2 ClientHello intolerant (even when inside V2 Client Hello) and 0.18% that are intolerant to regular TLSv1.2 client hello, rest seem to be intolerant to just big client hello or placement of RC4-SHA and RC4-MD5 ciphers after 64th position (Windows 2003 bug).

Supported curves

Around 56.7% of servers will negotiate ECDHE cipher suites. The vast majority of servers support the NIST prime256v1 curve (55.6% of all TLS-enabled) and high part of them support only this one curve (48.2%). Second most supported curve is secp384r1, where 7.3% of servers support it (0.02% support only this one). Third most supported curve is secp521r1, at 1.77%. Other curves hover around 0.13% mark, with the exception of brainpool curves (all 3 of them), which are supported by only 19 servers.

At the same time, there are servers which support only secp521r1, sect163k1 or sect163r2 curves – those servers won’t be able to negotiate ECDHE ciphers with common web browsers. This is because secp521r1 curve is supported only by some browsers (list that doesn’t include Firefox and Internet Explorer) while the other two are unsupported by all major browsers.

Interestingly, nearly all servers dictate the selected curve (use server side ordering for curves) – only 0.13% of servers let the client select the most preferred curve.

Many servers (11.8% of total) will abort connection completely in case the client does not support the curve preferred by server.

Signature algorithms in PFS TLSv1.2 key exchange

As more eagle-eyed readers of the RFC 5246 (TLSv1.2 definition) may have noticed, the standard also allows the peers to negotiate the signature algorithm used for signing the DHE and ECDHE key exchange. In detail it allows the server to sign the key exchange with MD5, SHA1 and SHA-2 family functions.

As we all know, MD5 is far from secure when used for digital signatures.

Unfortunately, many servers (24% of TLS-enabled) will sign the message with MD5 if the client “doesn’t leave them any choice”. Few (3 in total) will sign the key exchange only using MD5! The situation with the weak-but-no-broken-yet SHA1 is not much better as 8% of servers will use only it for signing.

On many servers support for SHA2 family of functions is still lagging a bit behind after SHA1 (respectively at around 42% and 51% of all).

Majority of servers will honour the client preferred signature mechanism (38% of TLS-enabled) while minority will take only its preference of it (18%).

In case the client doesn’t advertise any signature algorithm supported by server the behaviour is rather diverse. Most common is just forcing the client to accept SHA-1 signatures (at 23.9%), close second (at 23.7%) is aborting the connection if the client doesn’t advertise any RSA based signature algorithms. Less common still is aborting as soon as the client advertises only the unsupported signature algorithms (at 3.47%). Very few servers opt out to select ciphers that don’t require negotiation of signature algorithms (at 0.3%).

For servers with ECDSA keys, the situation is more uniform, where 5.5% of all TLS enabled servers will just force the SHA-1 signature algorithm, 20 servers will abort the connection while just one will drop down to RSA based, but still PFS-enabled cipher suite.

Cipher suites

Going back to our usual programming, use of cipher suites didn’t see much changes.

3DES ciphers have decreased a bit (2%) while AES-GCM have increased by a bit (also ~2%). While servers that support RC4 have decreased slightly (~1.5%) the amount of servers that force the use of RC4 remained essentially the same.

Amount of servers that will negotiate insecure cipher suites has grown by just under 2%, but this may be caused by addition of DES-CBC3-MD5 (at 8.7%), EXP-RC4-MD5 (at 11.7%), EXP1024-DES-CBC-SHA (at 2.3%), EXP1024-RC4-SHA (at 2.3%) and RC4-64-MD5 (at 0.39%) ciphers to the list of insecure ciphers which previously either were counted towards the RC4 and 3DES numbers or not tested at all (the EXP1024 ciphers).

It’s nice to see that more servers still use server side cipher ordering, this month at 66.7% (up by just under 6%).

We’ve also seen a 1.5% growth in servers that prefer PFS capable cipher suites, caused nearly entirely by servers that prefer the P-256 NIST curve for ECDHE key exchange.

Server certificates

A slight increase in the number of servers that have certificates signed by ECDSA keys, by 0.7%.

The other good news is that SHA-1 keeps on loosing, this month by 7.6% to a level of 68%.

The key sizes haven’t seen much changes, 2048bit is still dominant at 90.7% for RSA while 256 bit is dominant at 5.5% for ECDSA.

Looks like google have once again modified their Apple clients detection, as the number of servers that report support for both RSA and ECDSA ciphersuites have gone back to nearly 0 (and the scanning script once again doesn’t report support of ECDHE-ECDSA ciphers for sites like youtube.com).

Protocols

Administrators keep on updating their configurations, SSLv2 support has gone down by 1.5% to 8.8% while SSLv3 support has gone down by 23% to a level of 46% making it the first month when SSLv3 is supported by less than half the web servers.

A bit surprisingly, TLSv1.0 has gained a bit of market, from the previous 97.7% to current 99.2% making it virtually ubiquitous.

TLSv1.1 and TLSv1.2 have gained a bit less, at around 1.5% and 2% respectively.

Vulnerabilities

Some of the servers are still vulnerable to long known attacks requiring support for compression (at 4.3%) and lack of implementation of RFC 5746 (secure renegotiation) which is missing on nearly 6.5% of servers. This facilitates the CRIME and renegotiation attacks respectively.

Trust chains

The changes for individual certificates or trust chains in general are not significant, all are below the 1% mark, but they all go in the right direction – for higher security.
