A security vulnerability has been detected in Open5GS up to 2.7.6. Impacted is the function sgwc_s11_handle_create_indirect_data_forwarding_tunnel_request of the file /src/sgwc/s11-handler.c of the component SGWC. Such manipulation leads to reachable assertion. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. A patch should be applied to remediate this issue. The issue report is flagged as already-fixed.
Weakness
The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.

Extended Description
While assertion is good for catching logic errors and reducing the chances of reaching more serious vulnerability conditions, it can still lead to a denial of service. For example, if a server handles multiple simultaneous connections, and an assert() occurs in one single connection that causes all other connections to be dropped, this is a reachable assertion that leads to a denial of service.
