Analysis Summary

A zero-day vulnerability in Microsoft Office is being actively exploited in the wild, and while there isn’t currently a patch, the software giant has published workarounds to thwart attacks. CVE-2022-30190, also known as “Follina,” is a remote code execution (RCE) vulnerability affecting the Microsoft Support Diagnostic Tool (MSDT) in Windows. 

CVE-2022-30190

Microsoft Windows could allow a remote attacker to execute arbitrary code on the system, caused by a flaw in the Support Diagnostic Tool (MSDT) component. By persuading a victim to open specially-crafted content, an attacker could exploit this vulnerability to execute arbitrary code on the system.

Remediation

  • Use Microsoft Automatic Update to apply the appropriate patch for your system, or the Microsoft Security Update Guide to search for available patches.
  • Customers using Microsoft Defender Antivirus should turn-on cloud-delivered protection and automatic sample submission.
  • Customers that use Microsoft Defender for Endpoint can set the “BlockOfficeCreateProcessRule” attack surface reduction rule, which prevents Office apps from generating child processes.
