Mozilla Firefox 3.5.x < 3.5.18 Invalid HTTP Certificates

Medium Log Correlation Engine Plugin ID 801236

Synopsis

The remote host has a web browser installed that is vulnerable to multiple attack vectors.

Description

Versions of Firefox earlier than 3.5.18 have an out-of-date SSL certificate blacklist. A certificate authority (CA) has revoked a number of fraudulent SSL certificates for several prominent public websites.

If an attacker can trick someone into using the affected browser and visiting a malicious site using one of the fraudulent certificates, he may be able to fool that user into believing the site is a legitimate one. In turn, the user could send credentials to the malicious site or download and install applications.

Solution

Upgrade to Firefox 3.5.18 or later.
