I'm getting pretty frustrated trying to make McAffee whitelist a supposed exploit on a site i work on. The issue
is that their automated system has detected a supposed XSS exploit but the exploit only exists when
JavaScript is disabled. Given the fact that you need
JavaScript to be disabled for the exploit to exist then surely this means this
is not an exploit. Can anyone think of any possible arguments to the contrary?
Update - To add more detail:
The problem comes from in one place unsanitized URL content
is written to an anchor tag href.So, with JS disabled you could have something like this:
<a href="foor.php?"><script>alert('foo')</script>#someanchor" ..
When
JavaScript is enabled this href
is updated to be this (on dom ready):
<a href="javascript:;">link</a>
So, with JS enabled the link
is no longer injected, with JS disabled the alert would no longer execute.
