CVE-2022-41080 is a high-severity privilege escalation flaw impacting Microsoft Exchange Server 2013, 2016, and 2019. The vulnerability allows an attacker to elevate their privileges on the Exchange server and execute arbitrary code with SYSTEM privileges.
The vulnerability is caused by a flaw in the way Exchange Server handles user permissions. Specifically, the vulnerability exists due to the lack of proper validation of user input when handling access control requests. An attacker could exploit this vulnerability by sending specially crafted requests to the server, which would allow them to elevate their privileges to the system level. Once an attacker gains access, they can execute arbitrary code and gain control of the affected server.
Microsoft has released a security update that addresses the CVE-2022-41080 vulnerability. It is highly recommended that all affected users install the security update immediately to protect their systems. The latest version of Exchange Server that includes the patch is:
- Exchange Server 2013 Cumulative Update 24 (CU24)
