Executive Summary

[{'type': 'paragraph', 'content': 'The DBPower C300 HD Camera has a configuration disclosure vulnerability that allows unauthenticated attackers to download a configuration backup file from an unprotected endpoint. This backup file contains sensitive information such as hardcoded usernames and passwords.'}, {'type': 'paragraph', 'content': "The vulnerability exists because the camera's web interface exposes a configuration backup file without proper access controls, enabling attackers to retrieve it by sending an HTTP GET request to a specific URL path."}, {'type': 'paragraph', 'content': 'Additionally, the device uses client-side cookie-based authorization checks, which can be manipulated to escalate privileges from guest to admin, further compromising the device.'}] [1, 2]

Mitigation Strategies

Immediate mitigation steps include restricting access to the vulnerable configuration backup endpoint to prevent unauthorized downloads.

Since the vulnerability arises from improper access controls and weak authentication, it is recommended to:

• Disable or restrict access to the /web/cgi-bin/hi3510/backup.cgi endpoint on the device or network firewall.
• Change default credentials (e.g., admin:admin) to strong, unique passwords.
• Avoid using this camera firmware if possible, as it contains fundamental security flaws.
• Implement network segmentation to isolate the camera from critical network resources.

Long-term mitigation requires vendor firmware updates that enforce proper server-side authentication and access controls.

Detection Guidance

This vulnerability can be detected by attempting to access the vulnerable configuration backup endpoint on the DBPower C300 HD Camera. Specifically, sending an HTTP GET request to the path /web/cgi-bin/hi3510/backup.cgi can reveal if the device is exposing sensitive configuration data without authentication.

A practical detection method is to use command-line tools like curl or wget to request the backup file and check the response.

• curl -i http://<camera-ip>/web/cgi-bin/hi3510/backup.cgi
• wget http://<camera-ip>/web/cgi-bin/hi3510/backup.cgi -O config_backup.bin

If the HTTP response code is 200 and the file is retrieved, it indicates the vulnerability is present. The retrieved file may be gzipped and contain sensitive credentials such as usernames and passwords.
