Improper Validation of Integrity Check Value in RUCKUS FastIron firmware

IdentifiersCVE-2024-50604CWE-354

CVE-2024-50604 is an improper validation of integrity check value vulnerability in RUCKUS FastIron firmware used by the RUCKUS ICX switch product line. The issue is described as insufficient validation for a software component integrity check, indicating that the firmware does not adequately verify integrity metadata associated with software components. In the documented attack scenario, this weakness can be combined with CVE-2024-50607, a directory traversal vulnerability, to enable malware injection on vulnerable ICX switches. The affected scope includes multiple ICX firmware branches across the 08.0.95r, 09.0.10j, 10.0.10f, and 10.0.20b release lines.

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 can undermine the trust model for software component validation on affected switches. In the scenario described by the vendor and downstream detection content, an authenticated attacker with physical access can leverage this weakness together with CVE-2024-50607 to perform a malware injection attack. This can result in compromise of firmware or software components on the device and may lead to high-impact effects on confidentiality, integrity, and availability of the affected switch.

Mitigation

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

If immediate patching is not possible, restrict physical access to affected ICX switches, tightly limit authenticated administrative access, and reduce opportunities for local or maintenance-channel interaction with the device. Monitor for unauthorized firmware or software component changes and validate operational procedures around switch servicing and updates. Because the documented attack path involves chaining this flaw with another vulnerability, prioritize remediation of both related issues on exposed devices.

Remediation

Patch, then assume compromise.

Apply the vendor-provided fixes referenced in Ruckus Wireless Security Bulletin 332. The available information indicates that patches were published on 2025-02-21. Organizations should identify affected ICX platforms running vulnerable FastIron firmware branches and upgrade to the remediated firmware versions specified by the vendor.
