CVE-2022-35631: Filesystem race on temporary files

On MacOS and Linux, it may be possible to perform a symlink attack by replacing this predictable file name with a symlink to another file and have the Velociraptor client overwrite the other file. This issue was resolved in Velociraptor 0.6.5-2.

Security readout for executives and security teams

Plain-English summary

CVE-2022-35631 affects Rapid7 Velociraptor on macOS and Linux. The client used a predictable temporary filename, creating a race condition where another local actor could substitute a symlink and cause the client to overwrite a different file. Rapid7 states the issue was resolved in Velociraptor 0.6.5-2.

Executive priority

Treat this as a targeted maintenance priority for environments using Velociraptor clients on macOS or Linux. Business urgency rises on shared systems or sensitive endpoints, but the provided evidence does not support emergency treatment.

Technical view

The issue is classified as CWE-377: insecure temporary file handling. The source describes a filesystem race involving predictable temporary files and symlink replacement on macOS and Linux Velociraptor clients. CVSS is not provided in the bundle, and affected pre-fix version boundaries are not fully enumerated beyond the fix version.

Likely exposure

Exposure is most relevant where Velociraptor clients run on macOS or Linux systems, especially shared or multi-user hosts. The provided sources do not indicate Windows impact or a complete affected-version range.

Exploitation context

The bundle does not cite active exploitation, and the CVE is not listed as KEV. The described attack depends on replacing a predictable temporary filename with a symlink before the client writes to it.

Researcher notes

Key gaps are missing CVSS, incomplete affected-version boundaries, and no cited proof of exploitation. Validate exposure through installed client versions and operating systems rather than assuming broad product impact.

Mitigation direction

  • Upgrade Velociraptor to 0.6.5-2 or later.
  • Review Rapid7’s advisory for deployment-specific guidance.
  • Prioritize macOS and Linux Velociraptor clients for remediation.
  • Track unsupported or legacy client deployments separately.

Validation and detection

  • Inventory Velociraptor client versions on macOS and Linux assets.
  • Confirm clients are running 0.6.5-2 or later.
  • Check endpoint management records for stale Velociraptor agents.
  • Document any systems that cannot be upgraded immediately.
