Open5Gs ≤ 2.6.4
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-24428 is a high-severity Reachable Assertion (CWE-617) vulnerability in Open5Gs Open5Gs. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 41th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-24428 is a reachable assertion vulnerability in the oai_nas_5gmm_decode function of Open5GS versions up to and including 2.6.4. This flaw enables attackers to trigger a Denial of Service (DoS) condition through a crafted NGAP packet. The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and is associated with CWE-617.
An unauthenticated attacker with network access can exploit this vulnerability due to its low attack complexity and lack of required privileges or user interaction. By sending a specially crafted NGAP packet to an affected Open5GS deployment, the attacker triggers the assertion in the NAS 5GMM decoding process, resulting in a crash or service disruption that impacts availability without affecting confidentiality or integrity.
Mitigation details are available in the advisory published at https://cellularsecurity.org/ransacked, which was referenced alongside the CVE publication on 2025-01-21.

Developer testing and evaluation finds reachable assertions during development.
Security engineering principles discourage use of assertions for handling untrusted input.
Validating untrusted inputs structurally prevents attacker data from reaching and triggering assertions.
