Detection & IOCsextracted from sources · hover to see the quote
- →Attacker must be authenticated as at least a Site Owner on SharePoint to exploit; monitor for unusual code execution or file writes originating from SharePoint Site Owner-level accounts ↗
- →Attack is network-based, low complexity, and requires only low privileges (authenticated user); monitor SharePoint network traffic for anomalous remote code execution patterns from authenticated low-privilege users ↗
- →Exploitation is rated 'More Likely' by Microsoft; prioritize detection and patching of SharePoint Enterprise Server 2016 (KB5002692), SharePoint Server Subscription Edition (KB5002691), and SharePoint Server 2019 (KB5002705) ↗
- ·Vulnerability is an improper authorization flaw, not an authentication bypass; attacker must already hold a valid SharePoint account with at least Site Owner permissions ↗
- ·As of the advisory date, the vulnerability has NOT been publicly disclosed or exploited in the wild, but Microsoft rates exploitation as 'More Likely' ↗
- ·The security update KB5002692 for SharePoint Enterprise Server 2016 was made available on April 15, 2025; environments not yet patched remain at risk ↗
