Title
Vulnerability Affecting Office Macro Removal in CrowdStrike Falcon Sensor for Windows
Summary
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.

Title
CrowdStrike Falcon Sensor for Windows Logic Error
Summary
A logic error exists in the Falcon sensor for Windows that could allow an attacker, with the prior ability to execute code on a host, to delete arbitrary files. CrowdStrike released a security fix for this issue in Falcon sensor for Windows versions 7.24 and above and all Long Term Visibility (LTV) sensors.
There is no indication of exploitation of these issues in the wild. Our threat hunting and intelligence teams are actively monitoring for exploitation and we maintain visibility into any such attempts.
The Falcon sensor for Mac, the Falcon sensor for Linux and the Falcon sensor for Legacy Systems are not impacted by this.
CrowdStrike was made aware of this issue through our HackerOne bug bounty program. It was discovered by Cong Cheng and responsibly disclosed.

Title
Vulnerability Affecting Office Macro Removal in CrowdStrike Falcon Sensor for Windows
Summary
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.

Title
CrowdStrike Falcon Sensor for Windows Race Condition
Summary
A race condition exists in the Falcon sensor for Windows that could allow an attacker, with the prior ability to execute code on a host, to delete arbitrary files. CrowdStrike released a security fix for this issue in Falcon sensor for Windows versions 7.24 and above and all Long Term Visibility (LTV) sensors.
There is no indication of exploitation of these issues in the wild. Our threat hunting and intelligence team are actively monitoring for exploitation and we maintain visibility into any such attempts.
The Falcon sensor for Mac, the Falcon sensor for Linux and the Falcon sensor for Legacy Systems are not impacted by this.
CrowdStrike was made aware of this issue through our HackerOne bug bounty program. It was discovered by Cong Cheng and responsibly disclosed.

Title
CrowdStrike Falcon Sensor for Windows Logic Error
Summary
A logic error exists in the Falcon sensor for Windows that could allow an attacker, with the prior ability to execute code on a host, to delete arbitrary files. CrowdStrike released a security fix for this issue in Falcon sensor for Windows versions 7.24 and above and all Long Term Visibility (LTV) sensors.
There is no indication of exploitation of these issues in the wild. Our threat hunting and intelligence teams are actively monitoring for exploitation and we maintain visibility into any such attempts.
The Falcon sensor for Mac, the Falcon sensor for Linux and the Falcon sensor for Legacy Systems are not impacted by this.
CrowdStrike was made aware of this issue through our HackerOne bug bounty program. It was discovered by Cong Cheng and responsibly disclosed.
