No known exploits are currently observed in the wild.
AI Analysis
Technical Summary
This vulnerability in Open5GS up to version 2.7.7 involves improper handling in the SMF component's function smf_n4_build_qos_flow_to_modify_list, which can be manipulated remotely to cause a denial of service condition. The issue allows an attacker with low privileges to disrupt service availability without requiring user interaction or complex conditions. The vulnerability was reported early to the project but remains unaddressed with no official remediation available at this time.
Potential Impact
Successful exploitation results in denial of service, impacting the availability of the affected Open5GS SMF component. This could disrupt network functions relying on Open5GS, potentially affecting service continuity. The CVSS 4.0 base score is 5.3 (medium), reflecting network attack vector, low complexity, and low privileges required.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch has been released and the project has not responded, users should monitor the vendor's communications for updates. Until a patch is available, consider restricting access to the vulnerable SMF component from untrusted networks to reduce exposure.
