Detection & IOCs extracted from sources · hover to see the quote

• → Attacker must be authenticated with 'Manage List' permissions on the target SharePoint site to exploit this RCE vulnerability ↗
• → Privilege level required is low (PR:L) — monitor for low-privileged authenticated users performing unusual list management or code execution activity on SharePoint ↗
• → Attack vector is network-based; monitor inbound SharePoint HTTP/S requests from authenticated low-privileged users that trigger list management operations leading to process spawning ↗

• · Exploitation assessed as 'More Likely' for both latest and older software releases, despite no public exploit or in-the-wild exploitation confirmed at time of advisory ↗
• · For SharePoint Server 2013 SP1, the Cumulative Update already includes the Foundation Server 2013 security update — only one update needs to be installed, not both ↗
