Attackers are now targeting a chain of two Microsoft SharePoint vulnerabilities that can allow them to execute arbitrary code on unpatched servers, according to threat intelligence company Defused. [...]

Editorial Analysis

Why it matters

Public PoC availability and confirmed exploitation compress the window between disclosure and mass targeting; unpatched on-prem SharePoint is an easy entry point for ransomware operators.

What to do

Immediately verify patch status of all on-premises SharePoint servers and implement network-level access restrictions as a compensating control where patching is delayed.

Board brief

Attackers are actively exploiting a remote-code-execution chain in Microsoft SharePoint with a public exploit—unpatched on-premises servers are at immediate risk.
