KDE Security Advisory: Konqueror Cross-Domain Cookie Injection
Original Release Date: 2004-08-23
URL: http://www.kde.org/info/security/advisory-20040823-1.txt

0. References

1. Systems affected:

        KDE versions up to KDE 3.2.3 inclusive. KDE 3.3 is not affected.


2. Overview:

        WESTPOINT internet reconnaissance services alerted the KDE
        security team that the KDE web browser Konqueror allows websites
        to set cookies for certain country specific secondary top level
        domains.

        The Common Vulnerabilities and Exposures project (cve.mitre.org)
        has assigned the name CAN-2004-0746 to this issue.


3. Impact:

        Web sites operating under the affected domains can set HTTP
        cookies in such a way that the Konqueror web browser will send them
        to all other web sites operating under the same domain.
        A malicious website can use this as part of a session fixation
        attack. See e.g. http://www.acros.si/papers/session_fixation.pdf

        Affected are all country specific secondary top level domains that
        use more than 2 characters in the secondary part of the domain name
        and that use a secondary part other than com, net, mil, org, gov, 
        edu or int. Examples of affected domains are .ltd.uk, .plc.uk and
        .firm.in

        It should be noted that popular domains such as .co.uk, .co.in
        and .com are NOT affected.


4. Solution:

        Source code patches have been made available which fix these
        vulnerabilities. Contact your OS vendor / binary package provider
        for information about how to obtain updated binary packages.
