"The Microsoft Excel Products are missing a security update. They are, therefore, affected by multiple vulnerabilities:

  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute
    unauthorized arbitrary commands. (CVE-2025-59223, CVE-2025-59224, CVE-2025-59225, CVE-2025-59231,
    CVE-2025-59233)

  - An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive
    information. (CVE-2025-59232, CVE-2025-59235)

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