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-120 | The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a critical buffer overflow in the Belkin F9K1015 router version 1.00.10. It occurs in the handling of the 'pinCode' parameter within the HTTP route '/goform/formWpsStart'. An attacker can send a specially crafted request to this route, causing the device to overflow a buffer, which may lead to arbitrary code execution or denial of service. [1, 2]
How can this vulnerability impact me? :
The vulnerability can impact you by allowing a remote attacker to execute arbitrary code or cause a denial of service on the affected router. This compromises the confidentiality, integrity, and availability of the device, potentially disrupting your network and exposing it to further attacks. [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 HTTP requests to the router for attempts to access the `/goform/formWpsStart` endpoint with unusually long or malformed `pinCode` parameters that could trigger a buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such suspicious requests. Additionally, you can use tools like curl or wget to test the endpoint by sending crafted requests to see if the device responds abnormally or crashes. Example command to test the endpoint: `curl -X POST http://<router-ip>/goform/formWpsStart -d "pinCode=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA"` (replace with a long string to test buffer overflow). Monitoring logs for crashes or unexpected behavior after such requests can also help detect exploitation attempts. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting remote access to the affected router, especially blocking HTTP requests to the `/goform/formWpsStart` endpoint from untrusted networks. If possible, disable WPS functionality or the vulnerable service on the device. Since no vendor patch or official mitigation is available, it is strongly recommended to replace the affected Belkin F9K1015 router with a secure alternative. Additionally, monitor network traffic for exploitation attempts and consider implementing firewall rules to block suspicious requests targeting the vulnerable endpoint. [2]
