ZDI-26-485: (Pwn2Own) Kenwood DNR1007XR JKGenService Command Injection Local Privilege Escalation Vulnerability
This vulnerability allows local attackers to escalate privileges on affected installations of Kenwood DNR1007XR devices. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The ZDI has assigned a CVSS rating of 7.0. The following CVEs are assigned: CVE-2026-18268.
AI Analysis
Technical Summary
The Kenwood DNR1007XR device contains a command injection vulnerability in the JKGenService due to insufficient validation of user-supplied strings before executing system calls. This vulnerability enables a local attacker, who already has low-privileged code execution, to escalate privileges to root and execute arbitrary code with elevated rights. The vulnerability was reported to Kenwood on 2026-02-03 and publicly disclosed on 2026-07-29. Kenwood has issued a firmware update to remediate the issue.
Potential Impact
Successful exploitation allows a local attacker with limited privileges to escalate to root privileges, potentially leading to full system compromise, including confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Kenwood has issued an official firmware update to correct this vulnerability. Users of the Kenwood DNR1007XR device should apply the provided update from Kenwood's official firmware page to remediate this issue.
