CVE-2023-4542 Scanner

The D-Link DAR-8000-10 is a network device commonly used in enterprise networks for managing and routing network traffic efficiently. It's developed by D-Link Corporation, a well-known company specializing in networking equipment. The DAR-8000-10 is typically implemented in environments that require robust network management and supports a wide range of network protocols to enhance connectivity. This product is crucial in setting up secure and efficient corporate networks, providing reliable and scalable networking solutions. Network administrators leverage D-Link DAR product lines like this one to facilitate various networking tasks, including data transmission and inter-networking. Its versatility and reliability make it suitable for both small businesses and larger corporations that need advanced networking capabilities.

The vulnerability in question is a command injection in the D-Link DAR-8000-10 firmware, which can potentially allow an attacker to execute arbitrary commands on the system. Command injection occurs when the software interprets portions of a user input as commands to execute. In this case, specifically, the threat arises from unsanitized input being provided through the parameter 'id' of the file '/app/sys1.php'. Such vulnerabilities can lead to unauthorized command execution within the operating system, fundamentally jeopardizing the system’s integrity and the confidentiality of sensitive data managed by the device.

Technical details reveal that the underlying problem is due to inadequate input validation on the 'id' parameter within a particular system file ('/app/sys1.php'). Attackers can inject commands via this parameter, which the system subsequently processes unsafely, leading to potential system compromise. The injection point is specifically vulnerable to command line instructions which are executed by the operating system, showing a lack of effective filtration or sanitization in place to guard against such operations. This vulnerability can be abused to run unauthorized commands, leading to severe control over the system by malicious actors if left unpatched.

When exploited, this command injection vulnerability can allow attackers to gain control over the compromised device. Possible effects include revealing sensitive information, altering system configurations, and potentially using the device as a launching point for further attacks within the network. The ability to execute arbitrary commands provides the attacker significant leverage over the targeted device’s operation and data, posing a severe security risk demanding urgent remediation by network administrators using the D-Link DAR-8000-10.
