CVE Reference:
CAN-2005-1476, CAN-2005-1477
(Links to External Site)
|
Date: Jun 29 2005
|
Impact:
Execution of arbitrary code via network, User access via network
|
Fix Available: Yes Vendor Confirmed: Yes
|
Version(s): 1.7-7
|
Description:
Several vulnerabilities were reported in Firefox. A remote user can execute arbitrary code on the target user's system. Secure Web Browser for OpenVMS is affected.
A remote user can create specially crafted HTML that, when loaded by the target user, will execute arbitrary code on the target user's system.
A remote user can cause a Firefox chrome page to load a 'javascript:' URL with privileges. The addon install function can be made to display an icon containing a 'javascript:' URL to achieve this.
Because the vulnerable install function can only be loaded via 'update.mozilla.org' or 'addon.mozilla.org', the remote user must exploit a separate vulnerability to trigger the flaw. The onload() event can be exploited via a frame within a javascript page to access ostensibly restricted elements of the window object, such as the history. The history object can be accessed to navigate back to the calling javascript page and execute the page within the context of a window (displaying 'mozilla.org' web page content).
A demonstration exploit is available at:

Paul from Greyhats Security reported this vulnerability. Michael Krax assisted in researching this vulnerability.

Impact:
A remote user can execute arbitrary code on the target user's system.
