CVE-2026-18267 — Kenwood DNR1007XR Firmware Update Link Following Code Execution Vulnerability

Kenwood DNR1007XR Firmware Update Link Following Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Kenwood DNR1007XR devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the firmware update process. By creating a symbolic link, an attacker can abuse the service to move a file to an arbitrary location. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-28751.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Kenwood DNR1007XR).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.
