CVE-2023-34330: Code injection via Dynamic Redfish Extension interface

AMI SPx contains a vulnerability in the BMC where a user may inject code which could be executed via a Dynamic Redfish Extension interface. A successful exploit of this vulnerability may lead to a loss of confidentiality, integrity, and availability.

Security readout for executives and security teams

Plain-English summary

CVE-2023-34330 is a high-severity code injection flaw in AMI MegaRAC SPx BMC firmware. If exploited by a highly privileged local attacker, code could run through the Dynamic Redfish Extension interface and affect confidentiality, integrity, and availability of the BMC-managed system.

Executive priority

Treat as a high-priority infrastructure firmware issue, especially for data center or appliance fleets. Business urgency is higher where BMC management access is widely reachable or administrator accounts are shared.

Technical view

The CVE describes CWE-94 code injection in AMI SPx BMC firmware, affecting MegaRAC_SPx12 12.0 and MegaRAC_SPx13 13.0. CVSS 3.1 is 8.2 with local attack vector, low complexity, high privileges required, no user interaction, changed scope, and high C/I/A impact.

Likely exposure

Exposure is most likely in servers, appliances, or OEM platforms that include AMI MegaRAC SPx12 12.0 or SPx13 13.0 BMC firmware. The provided data does not identify all downstream OEM products.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. The CVSS vector indicates exploitation requires high privileges and local access, so this is not evidenced here as unauthenticated remote exploitation.

Researcher notes

The public bundle gives the vulnerable component, CVSS vector, CWE, and affected AMI product lines, but not detailed exploit prerequisites, vulnerable code paths, or patched version identifiers. Avoid assuming downstream OEM exposure without vendor confirmation.

Mitigation direction

  • Check AMI and affected OEM advisories for fixed BMC firmware guidance.
  • Prioritize firmware remediation for internet-adjacent or broadly reachable management planes.
  • Restrict BMC and Redfish access to dedicated management networks.
  • Remove unnecessary high-privilege BMC accounts and enforce strong administrative controls.
  • Monitor BMC administrative activity for unexpected extension or configuration changes.

Validation and detection

  • Inventory hardware for AMI MegaRAC SPx12 12.0 or SPx13 13.0 firmware.
  • Confirm affected status through AMI, OEM, or platform vendor advisories.
  • Review whether Redfish management interfaces are reachable outside trusted admin networks.
  • Verify only authorized administrators hold high-privilege BMC access.
  • Track remediation evidence by firmware version and vendor advisory reference.

Improper Control of Generation of Code ('Code Injection')

Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
