Version(s): Affects versions prior to 1.6|
A vulnerability was reported in the Mozilla browser in the processing of event handlers during the transition of documents. A remote user can conduct cross-site scripting attacks.|
The flaw reportedly resides in 'nsDOMClassInfo.cpp' and occurs when a large number of event handlers are used within HTML tags.
A remote user can create specially crafted HTML that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser in the context of an arbitrary site in that site's security domain. The code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
A limited amount of user interaction may be required.
The vendor was reportedly notified on December 2, 2003.
The original bug report (containing some demonstration exploit HTML) is available at:
