Detection & IOCsextracted from sources · hover to see the quote
- →CVE-2021-24078 is only exploitable on servers configured with the DNS Server role; non-DNS servers are not vulnerable. ↗
- →Exploitation can be triggered remotely by causing a vulnerable Windows DNS server to perform a recursive query for a previously unseen domain — e.g., via a phishing email containing a link or embedded image referencing a new domain. ↗
- →Microsoft rates exploitation as 'More Likely' for both latest and older software releases; prioritize patching Windows Server DNS roles accordingly. ↗
- ·Vulnerability only affects Windows Server systems configured with the DNS Server role; Windows desktop/client systems are not affected. ↗

[HIGH] Microsoft Patch Tuesday, February 2021 Edition
Microsoft today rolled out updates to plug at least 56 security holes in its Windows operating systems and other software. One of the bugs is already being actively exploited, and six of them were publicized prior to today, potentially giving attackers a head start in figuring out how to exploit the flaws.
Nine of the 56 vulnerabilities earned Microsoft’s most urgent “critical” rating, meaning malware or miscreants could use them to seize remote control over unpatched systems with little or no help from users.
The flaw being exploited in the wild already — CVE-2021-1732 — affects Windows 10, Server 2016 and later editions. It received a slightly less dire “important” rating and mainly because it is a vulnerability that lets an attacker increase their authority and control on a device, wh
