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.
