CrowdStrike released a security update to address a vulnerability in the Falcon sensor for Windows. The vulnerability only exists when the Microsoft Office File Malicious Macro Removal Windows policy setting is enabled and customers remain protected through the Cloud Anti-malware for Microsoft Office Files settings.




An update is available immediately for versions 7.34 and above, 7.32 LTS, and 7.16 for Windows 7/2008 R2 systems. The Falcon sensor for Mac, Linux, and Legacy Systems are not affected. 




This vulnerability could expose an arbitrary file write to protected locations from an unprivileged context, potentially leading to local privilege escalation.




The CrowdStrike Laroux Malware Cleanup Tool, based off of the same feature in the CrowdStrike Falcon sensor for Windows, is also affected. An update for this tool is also available immediately.
