Overview
A vulnerability in some Mozilla products that could allow a remote attacker to execute Javascript commands with the permissions of the user running the affected application.
Description
According to the Mozilla advisory on this issue: XULDocument.persist() did not validate the attribute name, allowing an attacker to inject XML into localstore.rdf that would be read and acted upon at startup. This could include JavaScript commands that would be run with the permissions of the browser. Note: Thunderbird could be vulnerable if JavaScript is enabled. This is not the default setting and we strongly discourage users from turning on JavaScript in mail. Thunderbird is not vulnerable in its default configuration. This vulnerability affects Mozilla Firefox, SeaMonkey, Thunderbird, and potentially any other Mozilla-based application. The exploit code for this vulnerability could be remotely supplied through a web page or in an email message. |
Impact
A remote attacker may be able to inject XML code, including JavaScript commands, into a startup file on the victim's system. This file would then be read and executed the next time the affected application is started. |
