Privilege escalation via attacker-controlled file path
Published Sep 12, 2023 · Updated Oct 30, 2025
External file-path control in Microsoft SharePoint Server affected 16.0 builds allows remote authenticated users to elevate privileges. CWE-73 establishes external control of a file or path name, but Microsoft has not disclosed the affected component or the file operation performed on that input. Low-privileged network access is required; successful exploitation elevates privileges, but the attained role and resulting actions remain undisclosed.
