Mozilla Firefox WYCIWYG:// URI Cache Zone Bypass Vulnerability

Mozilla Firefox WYCIWYG:// URI Cache Zone Bypass Vulnerability

Mozilla Firefox is prone to a cache-zone-bypass vulnerability because the application fails to properly block remote access to special internally generated URIs containing cached data.

Exploiting this issue allows remote attackers to access potentially sensitive information and to place markers with similar functionality to cookies onto targeted users' computers, regardless of cookie security settings. Information harvested in successful exploits may aid in further attacks.

Attackers may also potentially exploit this issue to perform cache-poisoning or URL-spoofing attacks.

This issue is being tracked by Mozilla's Bugzilla Bug 387333.
