Mitigate Zero-Day Vulnerabilities in Microsoft Exchange Server with MachPanel


While limited targeted attacks are being reported on Microsoft Exchange servers, Microsoft is already aware and investigating two reported zero-day vulnerabilities affecting mainly on-premises Microsoft Exchange Servers including Exchange Server 2013, Exchange Server 2016, and Exchange Server 2019. The two vulnerabilities reported are:

  • CVE-2022-41040: Server-Side Request Forgery (SSRF) vulnerability
  • CVE-2022-41082: Allows Remote Code Execution (RCE) when PowerShell is accessible to the attacker.

Are you already affected with Zero-Day Vulnerabilities in Microsoft Exchange Server?

As a first step you immediately have to verify if you are already affected or not and you can do that through below PowerShell command:

Get-ChildItem -Recurse -Path C:\inetpub\logs\LogFiles -Filter “*.log” | Select-String -Pattern ‘powershell.*autodiscover\.json.*\@.*200’

MachSol recommends that customers already using On-premise Exchange should follow Microsoft recommendations. In addition, MachPanel: MachSols leading automation solution for Enterprises, Governments and Cloud Service Providers for Multi-Cloud service delivery immediately responded to reported vulnerability and issued a hotfix to mitigate the threat. All existing customers of MachPanel can simply apply the hotfix which will disable the Remote PowerShell for all new Users and for existing users, they simply have to trigger Security permissions to disable the Remote PowerShell.
