grep'ing the Rails code revealed that encrypt() isn't used for the cookie by default. Upstream also reports that they are not vulnerable. Additionally even if encrypt() is used to encrypt data in a cookie there is also the digest at the end of the cookie string that might indicate tampering. ("might" b/c it depends on the implementation, which I didn't look at). I got no answer from the POET paper authors yet but it can be that CVE-2010-3299 is invalid.

I've assgiend two. The details are quite vague unfortunately. CVE-2010-3299 padding oracle attack: ruby on rails 2.3 CVE-2010-3300 padding oracle attack: owasp esapi Thanks.Hi, the paper [1], about practical padding oracle attacks mentions some programming frameworks as vulnerable (section 5): - Ruby On ails 2.3 - OWASP ESAPI I think they both need a CVE-ID. Thanks. Cheers Thomas [1] http://usenix.org/events/woot10/tech/full_papers/Rizzo.pdf
