Summary

CVE-2025-13306 is a low-severity Injection (CWE-74) vulnerability in Dlink Dwr-M920 Firmware. Its CVSS base score is 2.1 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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.

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

CVE-2025-13306 is a command injection vulnerability in D-Link routers, specifically the models DWR-M920, DWR-M921, DIR-822K, and DIR-825M running firmware version 1.1.5. The flaw affects the system function in the file /boafrm/formDebugDiagnosticRun, where manipulation of the 'host' argument enables command injection. Published on 2025-11-18, it carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) and is linked to CWEs 74, 77, and 78.

The vulnerability allows remote exploitation over the network with low complexity and no user interaction required, but attackers need low privileges (PR:L). Successful attacks can result in low-level impacts to confidentiality, integrity, and availability through injected commands.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

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

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

Secure engineering principles include proper neutralization and safe command construction practices.
