Arbitrary File Deletion in CrowdStrike Falcon Sensor for Windows

IdentifiersCVE-2025-42701CWE-367· Time-of-check Time-of-use (TOCTOU)…

CVE-2025-42701 is a race condition vulnerability in the CrowdStrike Falcon Sensor for Windows. According to the provided advisory text, an attacker who already has the ability to execute code on the affected host can exploit the flaw to delete arbitrary files. The issue affects Falcon Sensor for Windows prior to the security fix released in version 7.24, and CrowdStrike states that all Long Term Visibility (LTV) sensors are also covered by the fix. The vulnerability is specific to the Windows sensor; Falcon Sensor for Mac, Linux, and Legacy Systems are not affected. No further technical details about the specific vulnerable function or code path were provided in the supplied content.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary file deletion on the local host. Depending on which files are removed, this could enable denial of service, application or operating system instability, destruction of security tooling or logs, interference with recovery, or facilitation of follow-on compromise by removing protective or forensic artifacts. The advisory does not state that the flaw directly provides code execution or privilege escalation by itself; the stated impact is arbitrary file deletion by an attacker who already has code execution on the system.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce opportunities for local code execution on affected Windows hosts, since prior code execution is required for exploitation. Limit local administrative access, restrict execution of untrusted binaries and scripts through application control, monitor for unexpected file deletions affecting system, security, and application files, and prioritize patching on systems where Falcon Sensor for Windows is deployed. The provided content does not mention any vendor-supplied workaround other than applying the fix.

Remediation

Patch, then assume compromise.

Upgrade CrowdStrike Falcon Sensor for Windows to version 7.24 or later, and apply the vendor-provided security fix to all affected Long Term Visibility (LTV) sensors. Validate that Windows endpoints are running the remediated sensor version and that any unsupported or lagging sensor deployments are updated through normal endpoint management processes.
