Today Microsoft released several patches to address critical vulnerabilities.
A number of these were deemed critical enough to warrant the US Department of Homeland Security to issue an Emergency Directive ordering all Federal agencies to patch these vulnerabilities within the next ten days.
Vulnerabilities have been found in Windows CryptoAPI as well as with RDP clients and servers
The vulnerabilities are found in the Windows CryptoAPI, as well as Remote Desktop Protocol (RDP) on both RDP Gateway Servers and RDP Clients.
Here are the descriptions with links to the Microsoft Security Center so you can review the KB articles associated with them.
- CVE-2020-0601 is a CryptoAPI spoofing vulnerability and affects Windows 10, Server 2016, and Server 2019, and could potentially allow an attacker to bypass antivirus and perform malicious actions on an affected endpoint. It is listed as Important and Exploitation More Likely by Microsoft.
- CVE-2020-0609 and CVE-2020-0610 affect Remote Desktop Gateway on Windows Server 2012, 2012R2, 2016, and 2019 and could allow an attacker to execute code without any user interaction and with no authentication. These are listed as Critical and Exploitation More Likely by Microsoft.
- CVE-2020-0611 affects Remote Desktop Clients on all supported versions of Windows and Windows Server (including Windows 7) and could be exploited if a user is tricked into connecting to a Remote Desktop Server under the attacker’s control. This vulnerability is listed as Critical and Exploitation Less Likely.
There are no reported active exploits in the wild, the recommendation is to patch as soon as you can to avoid these being exploited by attackers scanning for weaknesses. We recommend also that you prioritise any internet facing computers as well.
If you are a customer on our support plans Mega, Giga or Tera, these patches will automatically be rolled out in the next schedule
