Description:
bitlance winter has discovered a weakness in Thunderbird, 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 Target 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. Other versions may also be affected.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, using the Network Software Inspector.
Solution:
The weakness has been fixed in some version. Update to version 1.5.0.2.
