    XSS Security flaw in Umbraco Core

    General

    We've just been alerted by our security team here that there is a XSS flaw in the Umbraco admin section.

    To replicate - you need to log in to Umbraco first and append this to the url ?app=content%27%3balert('xss')//#content

    So the url would look like this

    http://localhost/umbraco/umbraco.aspx?app=content%27%3balert('xss')//#content

    Has anyone else come across this? I find it hard to believe that it's not a known bug.

    Mark

    Hi Mark,

    Best bet is to raise an issue on CodePlex, (if you haven't already done so?)

    http://umbraco.codeplex.com/WorkItem/Create

    The core team will pick up the issue and assess the vulnerability.

    Cheers, Lee.
