Summary

CVE-2024-24451 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Cellularsecurity (inferred from references). Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked in the top 16.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SC-5 (Denial-of-service Protection) and SI-16 (Memory Protection).

Deeper analysis

CVE-2024-24451 is a stack overflow vulnerability (CWE-120) in the sctp_server::sctp_receiver_thread component of OpenAirInterface CN5G AMF (oai-cn5g-amf) up to version v2.0.0. Published on 2025-01-21, it 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), indicating high-impact availability disruption with network accessibility and low attack complexity.

Unauthenticated attackers can exploit the vulnerability remotely by repeatedly establishing SCTP connections to the N2 interface, triggering the stack overflow and causing a Denial of Service (DoS) that crashes the affected component.

Mitigation details are available in advisories from OpenAirInterface at http://openairinterface.com and the Cellular Security Research Group at https://cellularsecurity.org/ransacked.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Stack overflow in network-facing SCTP handler directly enables remote application/system crash for DoS via exploitation (T1499.004).
