Microsoft Exchange Vulnerability

Microsoft recently closed two critical vulnerabilities related to Exchange Server, including vulnerability 2022. These vulnerabilities affect an exchange server’s security architecture and require that an attacker be able to authenticate with a user account before gaining access to it. If the attacker is able to gain access to an orphaned account, they could use brute-force attacks to exploit the vulnerability. Both of these vulnerabilities require that the extended protection feature on Exchange Server be enabled.

There are two types of zero-day vulnerabilities: one that affects servers with the NFS role enabled and one that affects Exchange Server. Both vulnerabilities can lead to remote code execution if a server sends special requests to NFSv4.1. To protect yourself from the risks of this Microsoft Exchange vulnerability, it is important to disable NFSv4.1 in your server’s security settings and use v3 and v2 instead.

The MSDT vulnerability allows an attacker to access targeted emails and view sensitive data. An attacker can exploit this flaw in Word documents that call the server’s command-and-control center with arbitrary code. In addition to reading email content, an attacker can create new accounts and perform other actions. Microsoft has been aware of this flaw for several years and has issued patches for it today. Until today, there have been no reported exploits of this vulnerability.

The exploit for Exchange Server involves convincing a user to access a malicious server that allows them to read targeted email messages. The patch for the vulnerability is now available for Windows 10, XP, and Windows Server. By turning on Extended Protection for Exchange Server, you can block the attacker from accessing targeted email messages. This works as a temporary workaround, but it may have a negative impact on communications in your network. Once the patch is released, the vulnerability will be closed in a few months.

Microsoft Exchange Vulnerability 2022 Closed

The Microsoft Store has updated its security advisories for Exchange Server 2013 and 2016. The patches address these vulnerabilities and should be installed on any Exchange server connected to the internet. Although Microsoft hasn’t identified any attacks related to these vulnerabilities, the information it shares can help someone compromise a server. If you’re unsure, the techcommunity has published a detailed technical explanation and a list of affected versions. The update is available for Exchange Server 2013 and 2016, as well as Exchange Server 2019.

Microsoft is fixing 71 vulnerabilities with the March 2022 Patch Tuesday. Three were previously unknown and not actively exploited by hackers. Two of the other vulnerabilities are related to Microsoft’s Exchange Server. One vulnerability, CVE-2022-30190, was discovered by security researcher j00sean. It was later rated as Critical and released as a free patch. If your organization uses Exchange for email, you should update immediately.

Microsoft recommends users update their systems as soon as possible to mitigate this vulnerability. The latest patches have been released to resolve this vulnerability. Microsoft recommends customers contact Microsoft to download patches. If you aren’t already running the latest versions of Microsoft Exchange, you can check the latest version of Qualys to see if you are vulnerable to this vulnerability.
