AI-suggested

To mitigate CVE-2025-15419, organizations should immediately apply the official patch identified by commit 5aaa09907e7b9e0a326265a5f08d56f54280b5f2 to all affected Open5GS instances. Beyond patching, restrict local access to systems running Open5GS to trusted administrators only, employing strict access controls and monitoring for unauthorized access attempts. Implement host-based intrusion detection systems (HIDS) to detect anomalous behavior or crashes related to the sgwc_s5c_handle_create_session_response function. Regularly audit and harden the operating environment to reduce the risk of local compromise. Network segmentation can help isolate critical 5G core components from less trusted networks or users. Additionally, maintain up-to-date backups and incident response plans to quickly recover from potential denial of service events. Continuous monitoring of Open5GS logs and metrics for unusual session handling errors can provide early warning signs of exploitation attempts. Finally, consider deploying runtime application self-protection (RASP) or similar technologies to detect and prevent exploitation of known vulnerabilities in real time.

Description

A weakness has been identified in Open5GS up to 2.7.6. Affected by this issue is the function sgwc_s5c_handle_create_session_response of the file src/sgwc/s5c-handler.c of the component GTPv2-C Flow Handler. Executing a manipulation can lead to denial of service. The attack needs to be launched locally. The exploit has been made available to the public and could be used for attacks. This patch is called 5aaa09907e7b9e0a326265a5f08d56f54280b5f2. It is advisable to implement a patch to correct this issue.
