Secunia Advisory SA12712

Where:

From remote

Impact:

Spoofing

Solution Status:

Vendor Patch

CVE Reference(s):

Description


Secunia Research has discovered two vulnerabilities in Mozilla, Mozilla Firefox, and Camino, which can be exploited by malicious web sites to obtain sensitive information and spoof dialog boxes.

1) Inactive tabs can launch dialog boxes so they appear to be displayed by a web site in another tab. This can be exploited by a malicious web site to show a dialog box, which seems to originate from a trusted web site.

Successful exploitation would normally require that a user is tricked into opening a link from a malicious web site to a trusted web site in a new tab.

A test is available here:
http://secunia.com/multiple_browsers_dialog_box_spoofing_test/

The vulnerability has been confirmed in the following versions:
* Mozilla 1.7.2 and 1.7.3
* Mozilla Firefox 0.10.1
* Mozilla Firefox 1.0 (affected by variant)
* Camino 0.8

2) Inactive tabs can gain focus from form fields on web sites in another tab. This can potentially be exploited to collect sensitive data entered in form fields on other web sites.

Successful exploitation would normally require that a user is tricked into opening a link from a malicious web site to a trusted web site in a new tab.

A test is available here:
http://secunia.com/multiple_browsers_form_field_focus_test/

The vulnerability has been confirmed in the following versions:
* Mozilla 1.7.2 and 1.7.3
* Mozilla Firefox 0.10.1

Other versions may also be vulnerable.
