  • I've tested this and we fixed major vulnerability issues on V3.5GA that were still existing on V3.5RC.

    We need to see what they are talking about.

    In addition I'd like to inform that Newscoop has administration session cookies with HTTPOnly parameter (was introduced in 3.4.2 release). It prevents a session grabbing via any injected code - javascript has no access to session information.
  • The latest cross scripting vulnerability was on the frontend, not admin: a
    reader could write comments that contain Javascript code - this was fixed in
    3.5.0. The same possibility exists for the subscriber data form - this was
    not updated yet to filter out Javascript. The problem is minor though, I
    never heard of any site using the template based subscriber form to allow
    their readers to update personal data.

  • True, as Ofir said... there was an XSS problem re: Comments, Ofir
    reported it... and while fixing it I found a couple more, also fixed.
    One more was fixed by Martin and I think he also fixed the problem
    with Subscribers Mugur is mentioning.
