Summary

CVE-2024-24429 is a high-severity Reachable Assertion (CWE-617) vulnerability in Open5Gs Open5Gs. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 45th 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-2024-24429 is a reachable assertion vulnerability in the nas_eps_send_emm_to_esm function within Open5GS versions up to and including 2.6.4. This flaw allows attackers to trigger a Denial of Service (DoS) condition through a specially crafted NGAP packet. The vulnerability is rated with a CVSS v3.1 base score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H) and is associated with CWE-617 (Reachable Assertion). It was published on 2025-01-22.

Unauthenticated attackers with network access can exploit this vulnerability due to its low attack complexity and lack of required privileges or user interaction. By sending a malicious NGAP packet to a vulnerable Open5GS instance, an attacker can cause the assertion to fail, leading to a crash and high-impact availability disruption. The changed scope (S:C) indicates potential effects beyond the vulnerable component.
