Mozilla Firefox 3.6.x < 3.6.16 Invalid HTTP Certificates
Medium Nessus Network Monitor Plugin ID 5842
SynopsisThe remote host has a web browser installed that is vulnerable to multiple attack vectors.
DescriptionVersions of Firefox 3.6.x earlier than 3.6.16 have an out-of-date SSL certificate blacklist.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.
SolutionUpgrade to Firefox 3.6.16 or later.
