As of, March 10th, 2021, publicly available Proof-of-Concept (PoC) exploit code and in-depth technical details for two of the recent Microsoft Exchange zero-day vulnerabilities (known as ProxyLogon) has been confirmed. The PoC code will allow less skilled threat actors to exploit CVE-2021–26855 and CVE-2021–27065 and cause Remote Code Execution on vulnerable on-premise Exchange servers.
Widespread exploitation of these vulnerabilities is now imminent. Organizations that have not already applied the Microsoft security patches need to do so immediately.
What we’re doing about it
What you should do about it
The eSentire Threat Intelligence team has observed several markers towards mass exploitation of ProxyLogon vulnerabilities in the last 24 hours. Security firm Praetorian released technical details of the vulnerabilities on March 9th, but omitted publishing key details for exploitation. During the afternoon of March 10th, several reports of working Proof-of-Concept code emerged online. While we have not independently verified the PoC, several prominent security researchers have attested to their validity.
Given the increasing scope of widespread attacks over the past week and emergence of vulnerability details and working exploits, organizations must take immediate action to mitigate the vulnerabilities through security updates, workarounds or by restricting access to their on-prem Exchange servers.
