Overview
The vulnerability identified as CVE-2025-6562 is a severe and alarming security flaw that places the integrity of specific DVR models at risk. This vulnerability is present in certain hybrid DVR models from Hunt Electronic, notably the HBF-09KD and HBF-16NK. The flaw allows for an OS Command Injection vulnerability, an exploit that could permit remote attackers possessing regular privileges to inject and execute arbitrary OS commands on the device. Because of the high-risk potential for system compromise or data leakage, this vulnerability demands immediate attention and remediation.

How the Exploit Works
The OS Command Injection vulnerability inherent in the identified DVR models allows for remote attackers to exploit the flaw by sending specially crafted requests to the device. These requests can contain malicious OS commands that, once processed by the vulnerable application, are executed within the host system environment. This execution occurs with the same privileges as the application, thereby leading to potential system compromise or data leakage.
Conceptual Example Code
A conceptual example of how the vulnerability might be exploited might look like the following HTTP request:
POST /execute/command HTTP/1.1
Host: target_device_ip
Content-Type: application/json
{ "command": "rm -rf /*" }In this example, the HTTP request includes a JSON object with a command parameter that carries a destructive Linux command (`rm -rf /*`). This command, if executed, would delete all files in the system.
Please note that this is a conceptual example meant to illustrate the potential severity of the vulnerability. It should not be used to exploit any system.
