Local information disclosure via improper memory handling
Published Oct 16, 2020 · Updated Aug 4, 2024
Information disclosure in Microsoft SharePoint Server 2019 allows local users to obtain sensitive memory data through a crafted application. The server handles objects in memory incorrectly, but Microsoft has not identified the affected component, object type, or faulty memory operation. Exploitation requires a logged-on low-privilege user to run the application and interact with its attack mechanism; the disclosed impact is limited to obtaining information for further compromise.
