Mozilla Firefox '.url' Shortcut Processing Information Disclosure Vulnerability
Mozilla Firefox is prone to an information-disclosure vulnerability when processing '.url' shortcut files in HTML elements.
An attacker can exploit the issue to obtain sensitive information such as browser cache files, cookie data, or local filesystem details. Information harvested may aid in further attacks.
NOTE: To exploit this issue, the attacker must trick a victim into saving a malicious HTML file to the local system and then following a malicious URI.
Mozilla Firefox 3.0.1, 3.0.2, and 3.0.3 are reported vulnerable.
