Summary

CVE-2024-42756 is a high-severity Code Injection (CWE-94) vulnerability in Netgear Dgn1000Ww Firmware. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-42756 is a code injection vulnerability, tracked as CWE-94, affecting the Netgear DGN1000WW wireless router at firmware version 1.1.00.45. The flaw resides in the Diagnostics page and carries a CVSS 3.1 base score of 8.8, reflecting an adjacent-network attack vector that requires no authentication or user interaction.

An unauthenticated attacker positioned on the same network segment can submit crafted input to the Diagnostics page, resulting in arbitrary code execution on the device. Successful exploitation grants the attacker full control over confidentiality, integrity, and availability of the router.

Public references include a detailed proof-of-concept on GitHub and Netgear’s general security advisory page, although the references do not enumerate specific firmware patches or configuration mitigations. The associated EPSS score currently stands at 0.2019 with a recorded peak of 0.2061.

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.
