Security readout for executives and security teams
Plain-English summary
CVE-2025-46115 is a denial-of-service issue reported in Open5GS v2.7.3. A remote attacker can send a crafted PDU Session Modification Request that can make the service unavailable. The business impact is availability loss for affected mobile core functions, not confirmed data theft or code execution.
Executive priority
Prioritize for environments using Open5GS v2.7.3 in production or lab networks connected to untrusted signaling sources. Treat as an availability risk to mobile core services. If Open5GS is not deployed, no direct action is indicated beyond standard dependency monitoring.
Technical view
The CVE describes improper input handling/resource management in Open5GS v2.7.3, mapped to CWE-20 and CWE-400. CVSS 3.1 is 7.5: network-accessible, low complexity, no privileges or user interaction, with high availability impact only. The provided sources do not identify a fixed version or detailed vulnerable component.
Likely exposure
Organizations running Open5GS v2.7.3 are the stated exposure. Risk is highest where Open5GS components can receive untrusted or insufficiently filtered session-management signaling. The CVE metadata does not provide CPEs or a broader affected-version range.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. The reported attack path is a crafted PDU Session Modification Request causing denial of service. No public exploit status is established by the provided sources.
Researcher notes
Evidence is limited to the CVE record and the referenced Open5GS GitHub issue. The CVE lists high availability impact but does not provide CPEs, fixed versions, proof-of-exploit status, or detailed component scope. Avoid assuming impact beyond Open5GS v2.7.3 unless vendor updates expand scope.
Mitigation direction
- Check Open5GS issue 3858 and vendor guidance for patches or workarounds.
- Upgrade if Open5GS identifies a fixed release for this issue.
- Restrict Open5GS control-plane exposure to trusted network paths only.
- Monitor affected services for crashes, restarts, or abnormal session-modification failures.
Validation and detection
- Inventory Open5GS deployments and confirm whether v2.7.3 is running.
- Review Open5GS logs for denial-of-service symptoms around session modification handling.
- Verify network controls limit untrusted access to relevant Open5GS interfaces.
- Track the CVE record and GitHub issue for updated affected-version or fix details.
