MS KB3119884: Improperly Issued Digital Certificates Could Allow Spoofing

Medium Nessus Plugin ID 87313


The remote Windows host has an out-of-date SSL certificate blacklist.


The remote host is missing KB3119884, KB2677070 (automatic updater), or the latest disallowed certificate update using KB2813430 (manual updater). If KB2677070 has been installed, it has not yet obtained the latest auto-updates.

Note that this plugin checks that the updaters have actually updated the disallowed CTL list, not that the KBs listed are installed. This approach was taken since the KB2677070 automatic updater isn't triggered unless software that relies on SSL in the Microsoft Cryptography API is being actively used on the remote host.


Ensure that the Microsoft automatic updater for revoked certificates (KB2677070) is installed and running. Alternatively, install the manual updater (KB2813430).
