Improper input validation in Microsoft Office allows an unauthorized attacker to execute code locally.

The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities:

  - A remote code execution vulnerability. An attacker can     exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2025-47164,     CVE-2025-47167, CVE-2025-47173, CVE-2025-47953)

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