  3. CVE-2023-37013
Open5GS MME versions <= 2.6.4 contains an assertion that can be remotely triggered via a sufficiently large ASN.1 packet over the S1AP interface. An attacker may repeatedly send such an oversized packet to cause the `ogs_sctp_recvmsg` routine to reach an unexpected network state and crash, leading to denial of service.

Summary
  • (es) Las versiones de Open5GS MME anteriores a la 2.6.4 contienen una aserción que se puede activar de forma remota mediante un paquete ASN.1 lo suficientemente grande a través de la interfaz S1AP. Un atacante puede enviar repetidamente un paquete de este tamaño para provocar que la rutina `ogs_sctp_recvmsg` alcance un estado de red inesperado y se bloquee, lo que provoca una denegación de servicio.
