- Microsoft is issuing a security alert to its customers about yet another exploited vulnerability.
- Attackers may compromise your system by exploiting CVE-2021-42287 and CVE-2021-42278.
- Third parties with malicious intent may easily get Domain Admin credentials in Active Directory.
- The IT behemoth is now urging everyone to upgrade to the latest secure versions.
You should be aware that the Redmond-based tech firm has released an alert regarding various vulnerabilities that it has previously addressed but are currently being exploited on unpatched settings.
A proof-of-concept program exploiting these vulnerabilities was publicly revealed little over a week ago, on December 12.
Microsoft is advising users to address these flaws.
As you may recall, Microsoft provided a remedy for two new vulnerabilities, CVE-2021-42287 and CVE-2021-42278, during the November security update cycle.
Both of these flaws are classified as privilege escalation vulnerabilities in the Windows Active Directory domain service.
After compromising an ordinary user account, these flaws enable hostile third parties to quickly obtain Domain Admin rights in Active Directory.
The following three patches were provided by Redmond for instant deployment on domain controllers:
However, despite the fact that the aforementioned fixes have been available for some time, the issue is that a proof-of-concept program that exploits these vulnerabilities was just publicly released on December 12.
The Microsoft research team moved quickly and released a query that may be used to spot unusual activity that exploits these flaws.
This query compares aberrant device name changes to a list of domain controllers in your environment to discover abnormal device name changes (which should happen seldom to begin with).
If you believe you are a victim of one of the aforementioned instances, make sure you thoroughly investigate all of the information.
Most essential, upgrade to the safe versions supplied by Microsoft to ensure that you are always one step ahead of any possible risks.
