AI Analysis
Technical Summary
This vulnerability in Open5GS (up to version 2.7.7) affects the SMF component's function smf_nsmf_handle_created_data_in_vsmf. An attacker with low privileges can remotely manipulate this function to trigger a denial of service condition. The CVSS 4.0 score is 5.3 (medium severity), reflecting network attack vector, low complexity, no user interaction, and limited privileges required. The project has been informed but has not provided a remediation or patch at this time.
Potential Impact
Successful exploitation results in denial of service of the SMF component in Open5GS, potentially disrupting 5G core network functionality. The attack can be initiated remotely with low privileges and does not require user interaction. No evidence of active exploitation in the wild is currently reported.
Mitigation Recommendations
No official fix or patch is currently available from the Open5GS project. Users should monitor the vendor's advisories for updates. Until a patch is released, consider applying network-level protections to limit access to the SMF component and restrict exposure to untrusted networks. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
