Executive Summary

This vulnerability is a command injection flaw in the GL-iNet GL-MT3000 router up to version 4.4.5. It exists in the wg-server.generate_publickey function within the /cgi-bin/glc file of the wg-server.so Native Plugin. An attacker can remotely exploit this by manipulating the private_key argument to execute arbitrary commands on the device.

Detection Guidance

To detect this vulnerability, check if your GL-iNet GL-MT3000 device is running firmware version up to 4.4.5. Inspect the /cgi-bin/glc endpoint for the wg-server.generate_publickey function. Look for unusual command execution patterns or unexpected input handling in wg-server.so. No specific commands are provided in the context.

Impact Analysis

This vulnerability allows remote attackers to execute arbitrary commands on your GL-MT3000 router with high privileges. This could lead to complete system compromise, unauthorized access, data theft, or turning the device into a botnet node. The impact includes potential loss of control over the device and network.

Compliance Impact

This vulnerability allows remote command injection due to improper input handling in the wg-server.generate_publickey function. Such unauthorized remote access could lead to data breaches, unauthorized data access, or system compromise, which may violate compliance requirements under GDPR (data protection) and HIPAA (health data security).

Mitigation Strategies

Immediately update GL-iNet GL-MT3000 to a version beyond 4.4.5 to address the command injection flaw in wg-server.generate_publickey. Disable remote access to the vulnerable CGI endpoint /cgi-bin/glc if not required. Monitor network traffic for unusual activity targeting this component.
