Published: 18 November 2025
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 at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
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.
SI-10 directly prevents command injection by enforcing input validation and error handling on the untrusted 'host' argument at the vulnerable web endpoint.
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
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).
NVD Description
A security vulnerability has been detected in D-Link DWR-M920, DWR-M921, DIR-822K and DIR-825M 1.1.5. Impacted is the function system of the file /boafrm/formDebugDiagnosticRun. The manipulation of the argument host leads to command injection. Remote exploitation of the attack is possible.…

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.
