The Microsoft Exchange Server installed on the remote host is missing a security update. It is, therefore, affected by multiple vulnerabilities as referenced in the Nov, 2022 security bulletin.

  • Microsoft Exchange Server Spoofing Vulnerability (CVE-2022-41078, CVE-2022-41079)

  • Microsoft Exchange Server Elevation of Privilege Vulnerability (CVE-2022-41040, CVE-2022-41080, CVE-2022-41123)

  • Microsoft Exchange Server Remote Code Execution Vulnerability (CVE-2022-41082)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
