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.

A denial-of-service vulnerability has been identified in Open5GS versions through 2.7.6. The issue arises in the GTPv2-C Flow Handler, specifically within the 'sgwc_s5c_handle_create_session_response' function of 'src/sgwc/s5c-handler.c'. When processing a manipulated GTPv2-C session setup flow, SGW-C can crash and generate a core dump. This occurs after the session context is established, but an error is encountered due to a missing GTP TEID. The process then aborts, triggered by an assertion failure related to PFCP FAR activation, which disrupts normal operations and availability. This vulnerability requires local exploitation and has a publicly available proof-of-concept exploit.
Users are advised to update to the latest version of Open5GS, where this vulnerability has been fixed. The patch is available in the official Open5GS repository on GitHub.
