Testing for the original POODLE vulnerability was easy because it was an inherent problem with SSLv3, so if you find SSLv3 enabled then you’ve found POODLE (although other factors such as cipher suite preference have a role to play – see my previous post). Like Heartbleed, though, testing for POODLE over TLS is conceptually easy but it falls within a class of flaws that requires bespoke tools as an unpatched version of openssl, for example, won’t do what you want it to do. This article discusses how the Python tlslite library can be used to test for POODLE_TLS – and so much more. Continue reading →
