Firefox < 3.5.18 Invalid HTTP Certificates
Medium Nessus Plugin ID 52766
SynopsisThe remote Windows host contains a web browser with an out-of-date SSL certificate blacklist.
DescriptionThe installed version of Firefox is earlier than 3.5.18. Such versions have an out-of-date SSL certificate blacklist.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 3.5.18 or later.
