ZDI-26-485: (Pwn2Own) Kenwood DNR1007XR JKGenService Command Injection Local Privilege Escalation Vulnerability
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 specific flaw exists within the JKGenService. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-29066.
AI Analysis
Technical Summary
CVE-2026-18268 is a local privilege escalation vulnerability in the JKGenService component of Kenwood DNR1007XR devices. The vulnerability arises from insufficient validation of user-supplied strings used in system calls, enabling an attacker who already has low-privileged code execution to escalate privileges and execute arbitrary code as root. The Zero Day Initiative assigned this vulnerability a CVSS score of 7.0, indicating high severity. Kenwood has released a firmware update to fix this issue.
Potential Impact
An attacker with the ability to execute low-privileged code on the affected device can exploit this vulnerability to gain root-level privileges. This escalation allows execution of arbitrary code with full system control, potentially compromising the entire device.
Mitigation Recommendations
Kenwood has issued an official firmware update that corrects this vulnerability. Users of affected Kenwood DNR1007XR devices should apply the update promptly to remediate the issue.
