SSL/TLS Vulnerability Widely Unpatched 103

kaiengert writes "In November 2009 a Man-In-the-Middle vulnerability for SSL/TLS/https was made public (CVE-2009-3555), and shortly afterwards demonstrated to be exploitable. In February 2010 researchers published RFC 5746, which described how servers and clients can be made immune. Software that implements the TLS protocol enhancements became available shortly afterwards. Most modern web browsers are patched, but the solution requires that both browser developers and website operators take action. Unfortunately, 16 months later, many major websites, including several ones that deal with real world transactions of goods and money, still haven't upgraded their systems. Even worse, for a big portion of those sites it can be shown that their operators failed to apply the essential configuration hotfix. Here is an exemplary list of patched and unpatched sites, along with more background information. The patched sites demonstrate that patching is indeed possible."
