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:
Update to version 1.0.5.
