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-2023-24762 is an OS command injection vulnerability, tracked under CWE-78, that affects the D-Link DIR-867 wireless router running firmware version DIR_867_FW1.30B07. The flaw resides in the HNAP1 interface, specifically the SetVirtualServerSettings action, where the LocalIPAddress parameter is not properly sanitized before being passed to an operating system command.

Unauthenticated attackers with network access can supply a crafted LocalIPAddress value to execute arbitrary commands on the device. With a CVSS score of 9.8, successful exploitation grants full control over the router, enabling actions such as altering configuration, intercepting traffic, or using the device as a pivot point inside the network.

Public references point to a D-Link security bulletin page and a technical write-up on HackMD, though the supplied sources do not detail specific patch versions or mitigation steps beyond the general advisory link. The associated EPSS score remains low, with only a modest peak of 0.0548 that has since receded, indicating limited observed exploitation interest to date.

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).
