Weak configuration may lead to cryptographic issue when a VoWiFi call is triggered from UE.

Executive ViewAI

Why It Matters

A HIGH severity cryptographic vulnerability (CVE-2025-47383) affects 5G Fixed Wireless Access platforms, potentially compromising the security of VoWiFi calls when initiated from user devices. Organizations deploying this firmware are at immediate risk of call interception or manipulation, impacting customer trust and regulatory compliance until mitigation measures are implemented.

Business Impact: High

Compensating Controls

Disable VoWiFi call functionality on affected platforms until patch availability; implement strict network segmentation isolating 5G FWA infrastructure; deploy enhanced monitoring and alerting on call signaling traffic for anomalies; restrict administrative access to firmware configuration; require VPN tunneling for management interfaces; consider traffic inspection at network perimeter for VoWiFi call sessions if technically feasible.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
