An issue in the CreateUEContext handler component of free5gc v4.1.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted request.
AnalysisAI
Denial of service in free5gc v4.1.0's CreateUEContext handler allows unauthenticated remote attackers to crash or exhaust the 5G core network service by sending crafted UE context creation requests. The root cause is CWE-770 (Allocation of Resources Without Limits or Throttling) - the handler performs no rate limiting or resource bounding when processing incoming context requests. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network-level access to the free5gc v4.1.0 control-plane interface that exposes the CreateUEContext handler, consistent with the CVSS AV:N/AC:L/PR:N/UI:N vector - no authentication, no elevated privileges, and no user interaction are required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 7.5 (High) reflects a network-reachable, zero-complexity, unauthenticated path to full availability loss - the worst-case DoS profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch version has been identified in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all production deployments running free5gc v4.1.0 and assess network exposure of the CreateUEContext handler; if directly internet-facing, implement emergency network segmentation. …
