CVE-2025-1146
Published: 12 February 2025
Description
CrowdStrike uses industry-standard TLS (transport layer security) to secure communications from the Falcon sensor to the CrowdStrike cloud. CrowdStrike has identified a validation logic error in the Falcon sensor for Linux, Falcon Kubernetes Admission Controller, and Falcon Container Sensor where our TLS connection routine to the CrowdStrike cloud can incorrectly process server certificate validation. This could allow an attacker with the ability to control network traffic to potentially conduct a man-in-the-middle (MiTM) attack. CrowdStrike identified this issue internally and released a security fix in all Falcon sensor for Linux, Falcon Kubernetes Admission Controller, and Falcon Container Sensor versions 7.06 and above. CrowdStrike identified this issue through our longstanding, rigorous security review process, which has been continually strengthened with deeper source code analysis and ongoing program enhancements as part of our commitment to security resilience. CrowdStrike has no indication of any exploitation of this issue in the wild. CrowdStrike has leveraged its world class threat hunting and intelligence capabilities to actively monitor for signs of abuse or usage of this flaw and will continue to do so. Windows and Mac sensors are not affected by this.
Security Summary
CVE-2025-1146 is a validation logic error in the TLS connection routine of CrowdStrike's Falcon sensor for Linux, Falcon Kubernetes Admission Controller, and Falcon Container Sensor. This flaw causes incorrect processing of server certificate validation during secure communications from these components to the CrowdStrike cloud. Windows and Mac sensors are not affected. The vulnerability is rated at CVSS 3.1 score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-296.
An attacker with the ability to control network traffic between the affected sensors and the CrowdStrike cloud could exploit this issue to conduct a man-in-the-middle (MiTM) attack. Successful exploitation would allow compromise of confidentiality, integrity, and availability of those TLS-secured communications.
CrowdStrike's security advisory details that the company identified and fixed this issue internally through its security review process, releasing the patch in all Falcon sensor for Linux, Falcon Kubernetes Admission Controller, and Falcon Container Sensor versions 7.06 and above.
