CVE-2026-34005: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Xiongmai DVR/NVR devices
CVE-2026-34005 is a high-severity OS command injection vulnerability affecting Xiongmai DVR/NVR devices running firmware version 4. 03. R11. The flaw exists in the handling of the HostName value via an authenticated DVRIP protocol request on TCP port 34567, where shell metacharacters are not properly neutralized. This allows an attacker with authenticated access to execute arbitrary root commands on the device. The vulnerability arises because the system() function is used insecurely in the NetWork. NetCommon configuration handler. No patch or official remediation information is currently available.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-34005) affects Xiongmai DVR/NVR devices (models AHB7008T-MH-V2 and NBD7024H-P) running firmware 4.03.R11. It is an OS command injection issue (CWE-78) caused by improper neutralization of special elements in the HostName parameter processed via the authenticated DVRIP protocol on TCP port 34567. The vulnerable code uses the system() call with untrusted input, enabling an authenticated attacker to execute arbitrary commands as root on the device.
Potential Impact
Successful exploitation allows an attacker with authenticated access to execute arbitrary OS commands with root privileges on the affected device. This can lead to full compromise of the DVR/NVR, including confidentiality, integrity, and availability impacts. The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability with low attack complexity and no user interaction required.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict authenticated access to the DVRIP protocol on TCP port 34567 to trusted users only. Monitor for unusual activity and consider network-level controls to limit exposure. Do not expose the management interface to untrusted networks.
