Horizon Alert
Summary of the vulnerability and why it matters
The D-Link DNS-320 device, specifically its system management component, contains a flaw that allows unauthorized code execution. This vulnerability can be exploited remotely without requiring any credentials. The primary risk is that an attacker could gain control of the affected system, potentially leading to data compromise or disruption of services.
- Vulnerable system management component
- Allows remote code execution
- Potential for data compromise
Attack Path
How an attacker could exploit the issue
The identified command injection vulnerability in the system_mgr.cgi component of D-Link DNS-320 firmware allows for arbitrary code execution. This means an attacker could potentially gain control of the affected device by sending specially crafted commands through the network. Such an attack could impact the confidentiality, integrity, and availability of the device and any data it stores or processes.
- Exposed to the network.
- Attacker sends malicious commands.
- Arbitrary code execution.
