TLS Validation Logic Error in CrowdStrike Falcon Products

CVE-2025-1146

What is CVE-2025-1146?

CVE-2025-1146 is a vulnerability affecting CrowdStrike Falcon products, specifically the Falcon sensor for Linux, the Falcon Kubernetes Admission Controller, and the Falcon Container Sensor. These tools are designed to enhance endpoint security by monitoring and defending against various cyber threats. The identified vulnerability stems from a logic error in the TLS validation process, which secures communications between the Falcon agents and the CrowdStrike cloud. If exploited, this flaw could enable an attacker to conduct a man-in-the-middle (MiTM) attack, potentially compromising sensitive data and communications. Organizations utilizing these affected products face heightened risks if they do not implement the necessary security updates.

Technical Details

This vulnerability arises from improper processing of server certificate validation during TLS communications. This means that while CrowdStrike implements standard TLS protocols to secure data in transit, the validation logic error may lead to scenarios where malicious actors can mimic legitimate servers. The flaw primarily exists within the CrowdStrike Falcon sensor for Linux and associated products. In response to the discovery of this issue, CrowdStrike has released security patches for all affected software versions, specifically versions 7.06 and above.

Potential impact of CVE-2025-1146

1. Man-in-the-Middle (MiTM) Attacks: This vulnerability allows attackers who can control network traffic to intercept and manipulate communications between the Falcon products and the CrowdStrike cloud, potentially leading to data theft and unauthorized access.

2. Compromise of Security Monitoring: By exploiting this flaw, attackers could disable or bypass security monitoring functions provided by CrowdStrike products, leaving organizations vulnerable to other cyber threats without detection.

3. Impact on Compliance and Data Integrity: Organizations relying on CrowdStrike for compliance with various regulations may find their risk profiles significantly increased due to this vulnerability, jeopardizing their data integrity and compliance standings.
