Firefox "Save Link As..." Status Bar Spoofing Weakness

SECUNIA ADVISORY ID:
SA14565

VERIFY ADVISORY:
http://secunia.com/advisories/14565/

CRITICAL:
Not critical

IMPACT:
Spoofing

WHERE:
>From remote

SOFTWARE:
Mozilla Firefox 0.x
http://secunia.com/product/3256/
Mozilla Firefox 1.x
http://secunia.com/product/4227/

DESCRIPTION:
bitlance winter has discovered a weakness in Firefox, which can be
exploited by malicious people to trick users into saving malicious
files by obfuscating URLs.

The status bar cannot be manipulated via script code in the default
settings. However, it is still possible to display an incorrect URL
in the status bar when hovering the mouse over a link, right
clicking, and choosing "Save Link As...".

This can be exploited by including a nested link in a table inside a
link.

The weakness is related to:
SA13015

Example:
<a href="[TRUSTED_URL]">
<table><tr><td>
<a href="[MALICIOUS_URL]">download
</a>
</td></tr></table>
</a>

The weakness has been confirmed in version 1.0.1. Other versions may
also be affected.

SOLUTION:
Never save files via untrusted sources.

PROVIDED AND/OR DISCOVERED BY:
