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

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.
