Executive Summary

This vulnerability is a command injection flaw in Netcore NBR200V2 version 1.3.241127.071246. It exists in the Backup Restore component's restore.cgi file. An attacker can manipulate the QUERY_STRING argument to inject and execute arbitrary commands remotely. The exploit is publicly available, increasing the risk of attacks.

Detection Guidance

This vulnerability involves command injection via the QUERY_STRING parameter in the restore.cgi file of Netcore NBR200V2 1.3.241127.071246. To detect it, inspect network traffic for requests to /restore.cgi with unusual QUERY_STRING values. Check system logs for unexpected command execution or file modifications. Test with crafted inputs like QUERY_STRING=';id' to see if responses include system command outputs.

Impact Analysis

This vulnerability allows remote attackers to execute arbitrary commands on the affected system. This could lead to unauthorized access, data theft, system compromise, or disruption of services. Since the exploit is public, the risk of attacks is higher.

Compliance Impact

This vulnerability allows remote command injection via manipulation of the QUERY_STRING parameter in the restore.cgi component. Such unauthorized remote access could lead to data breaches, unauthorized data modification, or system compromise, which are critical violations under GDPR (data protection) and HIPAA (protected health information).

Mitigation Strategies

Immediately isolate affected Netcore NBR200V2 devices from the network to prevent remote exploitation. Disable the Backup Restore feature via the web interface or configuration files if possible. Monitor network traffic for unusual activity involving restore.cgi or QUERY_STRING parameters. Apply network-level controls to block external access to the device's web interface until a patch is available.
