My final response is here: http://ha.ckers.org/blog/20060706/google-disclosure-fallout/ This is the last I'm going to say on the subject. -RSnake http://ha.ckers.org/ http://ha.ckers.org/xss.html http://ha.ckers.org/blog/feed/ On Wed, 5 Jul 2006, Collin Jackson wrote:
There is a big difference between redirectors (which are part of Google's core functionality) and XSS vulnerabilities. I don't expect Google to ever get rid of redirectors. The behavior is by design and removing them would break dozens of Google web applications. Just because they made a conscious decision to allow redirection does not mean that Google would not take XSS vulnerabilities seriously. XSS vulnerabilities are much more of a security problem than redirection. -- Collin Jackson On 7/5/06, RSnake <rsnake () shocking com> wrote:Just for the record, I should clarify. Google was not notified of this exploit prior to full disclosure. As I said, they are notoriously slow (or completely delinquent) in fixing these issues historically. If you need proof click here to see four redirect issues disclosed nearly 6 months ago that are still not fixed. http://seclists.org/lists/webappsec/2006/Jan-Mar/0066.html Here's another one: http://www.google.com/url?sa=D&q=http://www.fthe.net Typically I don't believe in full disclosure as a release methodology (for instance, if I found a remote vulnerability in Microsoft, I wouldn't disclose that without giving Microsoft months to release a patch as they have taken their patching process very seriously as of late and their responsibility in this matter has been far improved). Either Google was not convinced when they were used as a phishing relay last time, or they do not take this seriously. Either way, it takes all but a few days to patch these issues in a website, QA them and releast them, and Google has not done so, making contacting the vendor a useless excersize to date, in my opinion.
