Summary

CVE-2025-15192 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 12% 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-2025-15192 is a command injection vulnerability affecting D-Link DWR-M920 routers in versions up to 1.1.50. The flaw exists in the sub_415328 function of the /boafrm/formLtefotaUpgradeQuectel file, where manipulation of the fota_url argument enables command injection. Published on 2025-12-29, it is rated at CVSS 6.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) and maps to CWEs CWE-74 and CWE-77.

A remote attacker with low privileges can exploit this vulnerability over the network with low attack complexity and no user interaction. Exploitation allows injection and execution of arbitrary commands, resulting in limited impacts to confidentiality, integrity, and availability.
