Security readout for executives and security teams
Plain-English summary
CVE-2024-24451 is a denial-of-service issue in OpenAirInterface CN5G AMF. An attacker able to reach the AMF N2 SCTP interface can repeatedly establish SCTP connections and crash or disrupt service. The reported impact is availability loss, not data theft or code execution.
Executive priority
Prioritize if OpenAirInterface CN5G AMF supports critical 5G testing, private network, or production services. The business risk is service disruption. If OAI CN5G AMF is not deployed, priority is low after confirmation.
Technical view
The CVE describes a stack overflow in sctp_server::sctp_receiver_thread in oai-cn5g-amf up to v2.0.0. CVSS 3.1 is 7.5: network reachable, low complexity, no privileges, no user interaction, availability high, confidentiality and integrity none. CWE is CWE-120.
Likely exposure
Exposure is most relevant to organizations running OpenAirInterface CN5G AMF with an N2 SCTP interface reachable by untrusted or insufficiently segmented networks. Internet exposure is not stated in the sources.
Exploitation context
The source bundle describes repeated SCTP connections to the N2 interface causing DoS. CISA KEV is false, and no provided source states active exploitation in the wild.
Researcher notes
Affected metadata in the CVE record is sparse, listing vendor and product as n/a, while the description names OpenAirInterface CN5G AMF. No patch version is provided in the bundle. Treat remediation status as incomplete until confirmed from project guidance.
Mitigation direction
- Identify any OpenAirInterface CN5G AMF deployments and their versions.
- Check OpenAirInterface or project guidance for a fixed release or workaround.
- Restrict access to the AMF N2 SCTP interface to trusted RAN components only.
- Apply network segmentation and rate controls where compatible with operations.
- Monitor AMF availability and SCTP connection patterns for abnormal spikes.
Validation and detection
- Confirm whether oai-cn5g-amf is deployed in lab, pilot, or production environments.
- Record AMF version and compare against the reported affected range: up to v2.0.0.
- Verify N2 SCTP exposure is limited to expected network peers.
- Review logs and telemetry for repeated SCTP connection attempts.
- Track vendor or project advisories for remediation status.
