Exploitation requires low complexity and no user interaction, but privileges are required. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability in Open5GS affects the gmm_handle_service_request function within the AMF component, leading to a denial of service condition when manipulated remotely. It impacts all versions up to and including 2.7.7. The CVSS 4.0 base score is 5.3 (medium), reflecting network attack vector, low attack complexity, no user interaction, and limited privileges required. The project has been informed but has not yet issued a fix or official response. No cloud service is involved, and no patch or mitigation guidance is currently available.
Potential Impact
Successful exploitation results in denial of service of the AMF component in Open5GS, potentially disrupting network service availability. The impact is limited to service interruption without elevation of privileges or data confidentiality/integrity compromise. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary workaround has been published, users should monitor the Open5GS project for updates. Until a patch is available, consider limiting exposure of the affected component to untrusted networks if feasible.
