Overview
The CVE-2025-10265 is a critical vulnerability discovered in certain models of Network Video Recorders (NVR) developed by Digiever. This vulnerability has the potential to allow authenticated remote attackers to inject arbitrary Operating System (OS) commands that can be executed on the device. Given that NVRs are typically used for surveillance purposes, such a breach could potentially result in unauthorized access to sensitive data, posing a significant threat to user privacy and security.
The significance of this vulnerability cannot be overstated. With an increasing number of businesses and individuals relying on surveillance systems for security, the compromise of such systems not only poses risks of data theft but also threatens physical security by disrupting surveillance operations.

How the Exploit Works
The exploit operates by utilizing the OS Command Injection vulnerability in the Digiever NVR. Once the attacker has authenticated access, they can inject arbitrary OS commands into the system. This is typically done via the device’s web interface, which does not sufficiently sanitize user-supplied inputs. These unsanitized inputs can then be executed by the system, allowing the attacker to execute arbitrary commands, potentially leading to system compromise or data leakage.
Conceptual Example Code
Here’s a conceptual example of how an HTTP request exploiting this vulnerability might look. Bear in mind, this is only a hypothetical example for illustration purposes:
POST /nvr_interface HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer <authenticated_token>
{ "os_command": "; rm -rf /" }In this example, the malicious `os_command` value is prefixed with a semicolon, which allows it to run as a separate command in many operating systems. The command `rm -rf /` is a destructive command that, if executed, would delete all files on the system.
Mitigation Guidance
To mitigate the vulnerability, users of affected models are strongly advised to apply the vendor patch as soon as it becomes available. As a temporary mitigation measure until the patch can be applied, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to help detect and prevent attempts to exploit this vulnerability.
