CVE-2025-25895, published on 2025-02-18, is an OS command injection vulnerability (CWE-78) in D-Link DSL-3782 v1.01, exploitable via the public_type parameter. The flaw enables attackers to execute arbitrary operating system commands by sending a crafted packet to the affected router.

According to its CVSS v3.1 base score of 8.0 (AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), the vulnerability can be exploited by attackers with adjacent network access and low privileges, requiring low complexity and no user interaction. Successful exploitation allows high-impact compromise of confidentiality, integrity, and availability, potentially leading to full system control on the device.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

SI-10 Information Input Validation good match

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

AC-6 Least Privilege partial match

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

CM-7 Least Functionality partial match

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require proper neutralization of untrusted input before command construction.

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).

Security testing and code review target insecure use of operating-system command interfaces, catching command-injection flaws introduced during development.
