A reachable assertion in the oai_nas_5gmm_decode function of Open5GS <= 2.6.4 allows attackers to cause a Denial of Service (DoS) via a crafted NGAP packet.

A reachable assertion in the amf_ue_set_suci function of Open5GS <= 2.6.4 allows attackers to cause a Denial of Service (DoS) via a crafted NAS packet.

open5gs v2.6.4 is vulnerable to Buffer Overflow. via /lib/core/abts.c.

Open5GS v2.6.4 is vulnerable to Buffer Overflow. via /lib/pfcp/context.c.

An issue was discovered in open5gs v2.6.6. SIGPIPE can be used to crash AMF.

An issue was discovered in open5gs v2.6.6. InitialUEMessage, Registration request sent at a specific time can crash AMF due to incorrect error handling of Nudm_UECM_Registration response.

Man in the Middle vulnerability, which could allow an attacker to intercept VNF (Virtual Network Function) communications resulting in the exposure of sensitive information.

An attacker could send an HTTP request to an Open5GS endpoint and retrieve the information stored on the device due to the lack of Authentication.

Invalid pointer release vulnerability. Exploitation of this vulnerability could allow an attacker to interrupt the correct operation of the service by sending a specially crafted json string to the VNF (Virtual Network Function), and triggering the ogs_sbi_message_free function, which could cause a service outage.

DOS vulnerability that could allow an attacker to register a new VNF (Virtual Network Function) value. This action could trigger the args_assets() function defined in the arg-log.php file, which would then execute the args-abort.c file, causing the service to crash.
