CVE-2020-16952 (GCVE-0-2020-16952)

Vulnerability from cvelistv5 – Published: 2020-10-16 22:18 – Updated: 2024-08-04 13:45

Title

Microsoft SharePoint Remote Code Execution Vulnerability

Summary

A remote code execution vulnerability exists in Microsoft SharePoint when the software fails to check the source markup of an application package. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the SharePoint application pool and the SharePoint server farm account. Exploitation of this vulnerability requires that a user uploads a specially crafted SharePoint application package to an affected version of SharePoint. The security update addresses the vulnerability by correcting how SharePoint checks the source markup of application packages.

Severity

8.6 (High)
