In a network-based attack, an unauthenticated attacker could write arbitrary code to inject and execute code remotely on the SharePoint Server.
According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?
A high attack complexity means that successful exploitation is complex and time‑consuming, requiring significant effort and precise conditions for an attacker to reliably exploit the vulnerability.
There are multiple update packages available for some of the affected software. Do I need to install all the updates listed in the Security Updates table for the software?
Yes. Customers should apply all updates offered for the software installed on their systems. If multiple updates apply, they can be installed in any order.
I am running SharePoint Server 2016. Do the updates for SharePoint Enterprise Server 2016 also apply to the version I am running?
