The Microsoft Office Web Apps installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:
An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2022-41060, CVE-2022-41103)
A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute unauthorized arbitrary commands. (CVE-2022-41061, CVE-2022-41063, CVE-2022-41106)
