Executive Summary

This vulnerability is a hidden functionality issue in Atsumi Electric Co., Ltd.'s ADX series DVRs. It allows an attacker with administrator privileges to execute arbitrary OS commands. The flaw exists in multiple models and firmware versions prior to 10.8.237, enabling unauthorized access to maintenance functions.

Detection Guidance

Check if your DVR models (ADX series) are running firmware versions prior to 10.8.237. For affected models, inspect network traffic for unauthorized OS command execution attempts or firmware upgrade activities. Use network scanning tools to identify vulnerable devices by their CPEs listed in the CVE.

Impact Analysis

If exploited, this vulnerability could lead to data manipulation, destruction, or leakage. It may also allow malware infection or using the device as a launchpad for further cyberattacks. Unauthorized firmware upgrades could cause data leaks, device misuse, or render the DVR inoperable.

Compliance Impact

This vulnerability could lead to unauthorized access, data manipulation, destruction, or leakage, which directly violates GDPR's data protection requirements and HIPAA's safeguards for protected health information. Unauthorized firmware upgrades may also introduce backdoors, further compromising compliance.

Mitigation Strategies

Upgrade firmware to version 10.8.237 for supported models (ADX5004, ADX5008, etc.). For unsupported models (ADX1004, ADX1008, ADX2016), disconnect from the network or replace with newer models like ADX5000 series. Reset passwords to stronger ones after upgrading.
