Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-24105 is a command injection vulnerability (CWE-94) discovered in the goform/formsetUsbUnload component of the Tenda AC15 V1.0 router running firmware version V15.03.05.18_multi. The flaw occurs because the value of the `v1` parameter is not properly validated before being passed to the doSystemCmd function, enabling potential arbitrary command execution. Published on 2026-03-02, it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical.
Unauthenticated attackers with network access can exploit this vulnerability with low complexity and no user interaction required. By crafting malicious requests to the affected endpoint, they can inject commands into doSystemCmd, potentially achieving high-impact confidentiality, integrity, and availability compromises, such as full device takeover, data exfiltration, or persistent access.

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
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 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

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.
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.
