Higher exposureElevatedModerateLower exposureUnknown / unassessed

CVSS colors follow its reported severity. Attack-factor colors describe each requirement, not an overall risk rating. Gray also covers absence from KEV; absence does not establish safety.

EPSS display bands: below 1% blue, 1–10% amber, 10–50% orange, 50% and above red. These are presentation bands, not FIRST severity categories. The trend compares daily EPSS probabilities, not percentile ranks; “pp” means percentage points. The sparkline shows relative movement, with its vertical scale fitted to the observed scores.

Vulnerability Description

SOCFortress CoPilot focuses on providing a single pane of glass for all your security operations needs. Prior to 0.1.77, POST /api/scoutsuite/generate-gcp-report in backend/app/integrations/scoutsuite/routes/scoutsuite.py admits admin and analyst users and validates the uploaded content as GCPScoutSuiteJSON, but passes raw file.filename from the multipart header to save_file_to_directory in backend/app/integrations/scoutsuite/services/scoutsuite.py. The writer combines this filename with scoutsuite-report using os.path.join without sanitization or a resolved-path containment check. A traversal filename therefore writes the supplied JSON outside the intended report directory. In the reported root-running backend, the researcher demonstrated root-owned writes outside that directory and into the application source directory. This permits host-file overwrite subject to the accepted JSON-content constraint and can disrupt application operation; the demonstrated primitive does not establish unrestricted executable contents or unconditional cross-tenant confidentiality loss. Version 0.1.77 removes caller-controlled filenames from the affected route; unrestricted-content and direct-code-execution claims require separate curator reconciliation.

  1. Maintain the observed Atomicorp protections. Keep your Atomicorp commercial rules current and confirm that the selected observed rules (340014 , 340023 , 340029 , 344360 , 344361 , 344363 , 344364 , 344366 , 344370 , 393655 ) have not been locally disabled. Atomicorp commercial rules are enabled by default. If you use Atomic WAF, review the applicable policy and rule settings.

  2. Apply the vendor’s remediation. WAF protection is defense in depth and does not replace upgrading or following the affected vendor’s guidance.

    • Affected versions: socfortress CoPilot version < 0.1.77.
    • No specific CNA/vendor solution or workaround is included in the current CVE Record . Review the vendor’s security advisories and supported-release guidance before making changes.

  3. Validate after changes. Confirm rule updates are current, review WAF events for the affected application, and test application behavior after vendor upgrades, mitigations, or local policy changes.

Research Notes

Atomicorp WAF protections are designed around attack techniques and exploit behaviors, allowing existing protections to apply across multiple vulnerabilities without requiring a unique rule for every CVE.

Research Note Context

This research note documents exploit-technique analysis associated with this vulnerability and references Atomicorp WAF protections observed during engineering review, testing, or validation activities.

Atomicorp security controls are generally designed to identify and mitigate attack techniques and exploit behaviors rather than individual CVE identifiers. As a result, protections developed for one vulnerability may also apply to related attack variants and future vulnerabilities using similar techniques.
