Exploitability
| CWE ID | Description |
|---|---|
| CWE-119 | The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |
| CWE-787 | The product writes data past the end, or before the beginning, of the intended buffer. |
| CWE-121 | A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-5630 is a critical stack-based buffer overflow vulnerability in the D-Link DIR-816 router firmware version 1.10CNB05. It occurs in the /goform/form2lansetup.cgi script when the 'ip' parameter is manipulated with an excessively long input without proper length validation. This causes a stack overflow, allowing remote attackers to crash the device or potentially execute arbitrary code without needing authentication. [1, 2]
How can this vulnerability impact me? :
This vulnerability can severely impact you by allowing remote attackers to compromise the confidentiality, integrity, and availability of the affected router. Exploitation can lead to device crashes or arbitrary code execution, potentially giving attackers control over the device. Since no authentication is required and public exploits exist, the risk is high, especially as no patches or countermeasures are currently available. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring network traffic for HTTP requests targeting the /goform/form2lansetup.cgi endpoint with unusually long or malformed 'ip' parameters, which may indicate exploitation attempts. Since the exploit is remote and unauthenticated, inspecting web server logs or using network intrusion detection systems (NIDS) with signatures for this specific buffer overflow attempt can help. Specific commands are not provided in the resources, but using tools like curl or wget to send crafted requests to the vulnerable endpoint could help verify if the device is affected. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include discontinuing the use of the affected D-Link DIR-816 router running firmware version 1.10CNB05, as no patches or countermeasures are currently available. Replacing the vulnerable device with a supported and updated model is strongly recommended to eliminate the risk. Additionally, restricting remote access to the device and monitoring for exploitation attempts can help reduce exposure until replacement. [2]
