Flaws have been found in the cookie path handling between a number of web browsers and web servers. The HTTP cookie standard allows a web server supplying a cookie to a client to specify a subset of URLs on the origin server to which the cookie applies. Web servers such as Apache do not filter returned cookies and assume that the client will only send back cookies for requests which fall within the server-supplied subset of URLs. However, by supplying URLs which use path traversal (/../) and character encoding, it is possible to fool many browsers into sending a cookie to a path outside of the originally specified subset. KDE version 3.1.3 and later include a patch to Konquerer that disables the sending of cookies to the server if the URL contains such encoded traversals. Red Hat Enterprise Linux 2.1 shipped with KDE 2.2.2 and therefore is vulnerable to this issue.
