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.

A request-validation issue was discovered in Open5GS 2.1.3 through 2.2.x before 2.2.1. The WebUI component allows an unauthenticated user to use a crafted HTTP API request to create, read, update, or delete entries in the subscriber database. For example, new administrative users can be added. The issue occurs because Express is not set up to require authentication.

Open5GS 2.1.3 listens on 0.0.0.0:3000 and has a default password of 1423 for the admin account.

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

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

Open5GS MME versions <= 2.6.4 contains an assertion that can be remotely triggered via a malformed ASN.1 packet over the S1AP interface. An attacker may send a UE Context Release Request message missing a required MMEUES1APID field to repeatedly crash the MME, resulting in denial of service.

Open5GS MME versions <= 2.6.4 contain a reachable assertion in the UE Context Release Request packet handler. A packet containing an invalid MMEUES1APID field causes Open5gs to crash; an attacker may repeatedly send such packets to cause denial of service.

An issue in Open5GS v.2.7.2 allows a remote attacker to cause a denial of service via the ogsdbiauthinfo function in lib/dbi/subscription.c file.

An issue was discovered in Open5gs v2.7.2. InitialUEMessage, Registration request sent at a specific time can crash AMF due to incorrect error handling of gmmstateexception() function upon receipt of the NausfUEAuthenticationAuthenticate response.

A vulnerability was found in Open5GS up to 2.7.2. It has been declared as problematic. Affected by this vulnerability is the function gmmstateauthentication of the file src/amf/gmm-sm.c of the component AMF. The manipulation leads to denial of service. The attack can be launched remotely. This vulnerability allows a single UE to crash the AMF, resulting in the complete loss of mobility and session management services and causing a network-wide outage. All registered UEs will lose connectivity, and new registrations will be blocked until the AMF is restarted, leading to a high availability impact. The exploit has been disclosed to the public and may be used. The patch is named e31e9965f00d9c744a7f728497cb4f3e97744ee8. It is recommended to apply a patch to fix this issue.
