Description
A vulnerability was identified in Open5GS up to 2.7.7. This affects the function pcf_npcf_smpolicycontrol_handle_delete of the file src/pcf/sm-sm.c of the component delete Endpoint. The manipulation leads to denial of service. The attack can be initiated remotely. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.
A denial-of-service vulnerability has been identified in Open5GS versions through 2.7.7. The issue arises in the Policy Control Function (PCF) component, specifically within the 'pcf_npcf_smpolicycontrol_handle_delete' function of 'src/pcf/sm-sm.c'. The vulnerability allows for remote exploitation, where an attacker can disrupt the PCF session state by sending a 'GET' request to the '/npcf-smpolicycontrol/v1/sm-policies/{smPolicyId}/delete' endpoint. This endpoint is intended to be accessed with a 'POST' request that includes a specific body, but the PCF incorrectly processes the 'GET' request as a delete operation. The resulting error is escalated into a state-machine exception, clearing the entire session context.
