CVE reference:CVE-2005-4678


Description:
A weakness has been reported in Safari, which can be exploited by malicious people to trick users into visiting a malicious website by obfuscating URLs displayed in the status bar.

The problem is that the browser fails to show the correct URL in the status bar if an image control has been enclosed in a hyperlink and uses a form to specify the destination URL. This may cause a user to follow a link to a seemingly trusted website when in fact the browser opens a malicious website.

This is related to:
SA17565

Example:
<form action="[malicious site]">
<a href="[trusted site]"><input type="image" src="[image]"></a>
</form>

The weakness has been confirmed in version 2.0.2 (416.12). Other versions may also be affected.

Solution:
Do not follow links from untrusted sources.

Provided and/or discovered by:
