The Microsoft Excel Products are missing security updates. They are, therefore, affected by multiple vulnerabilities:
A session spoofing vulnerability exists. An attacker can exploit this to perform actions with the privileges of another user. (CVE-2023-23398)
A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute unauthorized arbitrary commands. (CVE-2023-23399)
