A vulnerability was reported in Mozilla in the processing of cookies. A remote user may be able to bypass the path restrictions specified by a cookie's originator. Several other browsers are also affected.|
Corsaire reported that a remote user (server) can employ a combination of path traversal and encoding techniques to bypass cookie path restrictions in the target user's browser.
Malicious software on a server can obtain cookies from the target user's browser that should be restricted to a separate application path on the same server.
A demonstration exploit URL format is provided:
In the above example format, the 'insecure.cgi' application can obtain cookies that are ostensibly restricted to the '/secure' path.
The affected vendors were reportedly notified between July 12 and July 18, 2003.
A remote server application can obtain cookies from the target user's browser for the same domain but regardless of the path restrictions.|
