Technical details
A server-side request forgery (SSRF) vulnerability in Microsoft Office SharePoint permits an authorized attacker to manipulate the server into making arbitrary network requests. The vulnerability can be exploited over an adjacent network and may enable spoofing attacks. The attack requires authentication but allows an attacker to bypass network segmentation and interact with internal or adjacent systems as if the request originated from the SharePoint server itself.
