| 제목 | Open5GS SGWC v2.7.6 Denial of Service |
|---|
| 설명 | Open5GS SGW-C crashes on a malformed GTPv2-C Create Session Request where the Bearer Contexts To Be Created includes an S1-U eNB F-TEID whose flags byte is zero (no IPv4/IPv6). The handler sgwc_s11_handle_create_session_request calls ogs_gtp2_f_teid_to_ip and asserts on OGS_OK, leading to process abort:
Assert location: src/sgwc/s11-handler.c:346
Fatal log example: Assertion 'OGS_OK == ogs_gtp2_f_teid_to_ip(enb_s1u_teid, &dl_tunnel->remote_ip)' failed. |
