25 CVEs That NSA Wants You to Patch Right Now

Tuesday, October 20th, wasn’t your usual Patch Tuesday announcement from Microsoft.

Instead, this announcement came from the NSA urging users to patch 25 vulnerabilities Chinese hackers were exploiting, quickly.

The list of vulnerabilities, many of them already known programming issues, was made public to draw urgency and help IT teams prioritize these patches. Of the 25, seven affect remote access gateways, seven involve internal servers, one affects mobile devices management, two are privilege escalations, two affect Active Directory, three involve network equipment, and three affect public-facing servers, per this infographic from the NSA.

We realize you may not be able to patch all vulnerable assets instantly. We recommend that you prioritize systems for patching based on risk: exposure, asset criticality and any applicable compensating controls. You can learn more about risk based prioritization here.

9. CVE-2020-1472

CVE-2020-1472: An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using Microsoft’s Netlogon Remote Protocol (MS-NRPC).

10. CVE-2019-1040

CVE-2019-1040: A tampering vulnerability exists in Microsoft Windows when a miscreant-in-the-middle attacker is able to successfully bypass the NTLM MIC (Message Integrity Check) protection.

CVEs Targeting Public Facing Servers

11. CVE-2020-1350

CVE-2020-1350: A remote code execution vulnerability exists in Microsoft Windows Domain Name System servers when they fail to properly handle requests.

12. CVE-2018-6789

CVE-2018-6789: An issue was discovered in the base64d function in the SMTP listener in Exim. By sending a handcrafted message, a buffer overflow may happen. This can be used to execute code remotely.

13. CVE-2018-4939

CVE-2018-4939: Adobe ColdFusion Update 5 and earlier versions, ColdFusion 11 Update 13 and earlier versions have an exploitable deserialization of untrusted Data vulnerability. Successful exploitation could lead to arbitrary code execution.

CVEs Targeting Internal Servers

14. CVE-2020-0688

CVE-2020-0688: A remote code execution vulnerability exists in Microsoft Exchange software when the software fails to properly handle objects in memory

15. CVE-2015-4852

CVE-2015-4852: The WLS Security component in Oracle WebLogic Server 10.3.6.0, 12.1.2.0, 12.1.3.0, and 12.2.1.0 allows remote attackers to execute arbitrary commands via a crafted serialized Java object in T3 protocol traffic to TCP port 7001.

16. CVE-2019-11580

CVE-2019-11580: Atlassian Crowd and Crowd Data Center had the pdkinstall development plugin incorrectly enabled in release builds. Attackers who can send unauthenticated or authenticated requests to a Crowd or Crowd Data Center instance can exploit this vulnerability to install arbitrary plugins, which permits remote code execution on systems running a vulnerable version of Crowd or Crowd Data Center.
