Deeper analysis AI-assisted summary

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

D-Link Go-RT-AC750 firmware revision revA_v101b03 contains a command-injection flaw (CWE-78) in the genacgi_main function, where the service parameter is passed to the operating system without adequate sanitization. The vulnerability received a CVSS 3.1 base score of 9.8, reflecting network-accessible exploitation that requires neither authentication nor user interaction.

An unauthenticated attacker who can reach the device’s web interface can supply a crafted service value that results in arbitrary command execution, granting complete control over the router’s operating system, configuration, and any attached network resources.

D-Link has published a security bulletin addressing the affected model; administrators should consult the vendor advisory for available firmware updates or configuration guidance.

The CVE maintains a high EPSS score (current 0.6355, peak 0.6895), and public technical details including a proof-of-concept have been posted on GitHub, indicating sustained interest in the issue after disclosure.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
