Mozilla Firefox contains a vulnerability that may allow an attacker to bypass security restrictions by opening specially crafted URIs using the Firefox command line interface.
Mozilla Firefox can process URIs from its command line interface that can be accessed by users or programs. Passing Firefox multiple URIs through the command line interface using the pipe symbol will launch Firefox with the URIs opened in tabs. An attacker could use this feature pass URIs to Firefox that should be handled by another application. Since Firefox may determine that the URI sent to it is from a local content source, domain and origin-based security restrictions that usually apply to remote content may be bypassed.
A remote attacker may be able to use this vulnerability to bypass security restrictions, or to aid in the exploitation of other vulnerabilities.
Per Mozilla Foundation Security Advisory 2008-35 this issue has been addressed in Firefox 3.0.1 and Firefox 18.104.22.168.
Thanks to Mozilla for information that was used in this report. Mozilla credits Billy Rios for reporting this issue and Ben Turner and Dan Veditz for discovering additional attack vectors.
