Synopsis

The Microsoft Office Products are missing a security update.

Description

The Microsoft Office Products are missing a security update. It is, therefore, affected by multiple vulnerabilities, as follows:

- A remote code execution vulnerability. (CVE-2023-36895)

- A runtime spoofing vulnerability. (CVE-2023-36897)

The missing office update will also enhances security as a defense in depth measure. The update stops the attack chain that can lead to the Windows Search Remote Code Execution Vulnerability (CVE-2023-36884). Note that this does not mean the product is necessarily vulnerable to this CVE, only that this update provides extra mitigation. (ADV230003)

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

Solution

For Office 365, Office 2016 C2R, or Office 2019, ensure automatic updates are enabled or open any office app and manually perform an update.
