Overview
In today’s cybersecurity arena, a new vulnerability has surfaced that poses a significant risk to security systems across the globe. The vulnerability, classified under the Common Vulnerabilities and Exposures (CVE) system as CVE-2025-10264, affects certain models of Network Video Recorders (NVR) developed by Digiever. This vulnerability allows unauthenticated remote attackers to access the system configuration file and obtain plaintext credentials of the NVR and its connected cameras. Given the high severity of this vulnerability, understanding it and implementing mitigation strategies is crucial for every organization that uses Digiever NVR models.

How the Exploit Works
The security flaw in the Digiever NVR models stems from an inadequate protection mechanism that allows unauthorized access to the system configuration file. The system configuration file contains plaintext credentials of the NVR and its connected cameras, which, when in the wrong hands, can lead to a full system compromise. The attacker does not need any special privileges or user interaction to exploit this vulnerability. A simple network-based attack can open the door to the sensitive information stored in the system configuration file.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. This example uses an HTTP GET request to access the system configuration file:
GET /system_config HTTP/1.1
Host: target.example.comUpon a successful request, the server responds with the system configuration file containing the plaintext credentials of the NVR and its connected cameras.
Mitigation Guidance
To mitigate this vulnerability, users are advised to apply the latest patch provided by Digiever. In cases where immediate patching is not possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation, while preventing unauthorized access to the system configuration file. However, these measures are merely stopgap solutions, and organizations should prioritize patching their systems to effectively secure their NVRs against this critical vulnerability.
