CVE-2024-24421 is a type confusion vulnerability in the nas_message_decode function of Magma versions up to and including 1.8.0. Magma, an open-source platform for building access gateways and core networks in cellular deployments, is affected by this issue, which was published on 2025-01-21.

The vulnerability can be exploited remotely by unauthenticated attackers with low complexity and no user interaction, as reflected in its CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). By sending a crafted NAS packet, attackers can achieve arbitrary code execution or cause a denial of service. It is classified under CWE-94 (Code Injection).

The issue is fixed in Magma v1.9 via commit 08472ba98b8321f802e95f5622fa90fec2dea486. Additional details are available in the advisory at https://cellularsecurity.org/ransacked.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
