CVE-2020-37157

DBPower · C300 HD Camera

DBPower C300 HD Camera contains a configuration disclosure vulnerability. Unauthenticated attackers can retrieve sensitive credentials via an unprotected configuration backup endpoint.

Executive summary

The DBPower C300 HD Camera suffers from a critical configuration disclosure vulnerability that allows unauthenticated attackers to steal sensitive credentials.

Vulnerability

This vulnerability involves an unprotected configuration backup endpoint. An unauthenticated attacker can access this endpoint to download configuration files containing sensitive credentials and system settings without any form of authentication.

Business impact

The impact of credential theft from an IoT device is severe, as it allows attackers to gain full administrative control over the camera. This could lead to unauthorized surveillance, loss of privacy, and the potential for the device to be recruited into a botnet. The CVSS score of 7.5 reflects the high risk associated with the ease of access to these sensitive credentials.

Remediation

Immediate Action: Update the camera firmware to the latest version provided by DBPower to secure the backup endpoint.

Proactive Monitoring: Monitor for unusual outbound traffic from IoT devices and audit web server logs for hits on backup or configuration file paths.

Compensating Controls: Disable any unnecessary cloud or remote access features on the camera and ensure it is behind a robust firewall that restricts access to the web management interface.

Exploitation status

Public Exploit Available: false

Analyst recommendation

Immediate remediation is required to prevent the unauthorized disclosure of device credentials. Organizations and home users should verify firmware versions and ensure that these devices are not exposed to the public internet, as the unauthenticated nature of the flaw makes it highly exploitable.
