Summary

CVE-2025-13306 is a medium-severity Injection (CWE-74) vulnerability in Dlink Dwr-M920 Firmware. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 CM-7 (Least Functionality) and SI-10 (Information Input Validation).

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

SI-2 requires timely identification, reporting, and correction of the specific command injection flaw in the /boafrm/formDebugDiagnosticRun function of vulnerable D-Link router firmware.

prevent

SI-10 directly prevents command injection by enforcing input validation and error handling on the untrusted 'host' argument at the vulnerable web endpoint.

prevent

CM-7 mitigates the vulnerability by configuring the router to provide only essential capabilities and prohibiting unnecessary debug diagnostic functions like formDebugDiagnosticRun.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.008 Network Device CLI Execution
Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.
Why these techniques?

Command injection in the router's web diagnostic form directly enables exploitation of a public-facing application (T1190) and facilitates arbitrary command execution on the network device CLI (T1059.008).

Deeper analysisAI

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.
