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 pppUserName parameter within the /goform/formPPPoESetup HTTP endpoint. The router copies input data to a buffer without checking if the input size exceeds the buffer size, causing a buffer overflow. This flaw can be exploited remotely to execute arbitrary code or cause a denial of service on the device. [1, 2]
How can this vulnerability impact me? :
Exploitation of this vulnerability can compromise the confidentiality, integrity, and availability of the affected router. An attacker can remotely execute arbitrary code or cause the device to crash, leading to denial of service. This can disrupt network connectivity and potentially allow unauthorized control over the router. [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 endpoint /goform/formPPPoESetup on the Belkin F9K1015 router version 1.00.10, specifically looking for unusually long or malformed pppUserName parameters that could trigger the buffer overflow. Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to alert on such suspicious requests. Additionally, reviewing router logs for unexpected crashes or reboots may indicate exploitation attempts. Specific commands are not provided in the resources. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include discontinuing use of the affected Belkin F9K1015 router version 1.00.10, as no patches or vendor fixes are available. Consider replacing the device with a secure alternative. Restrict network access to the router's management interface, especially blocking external HTTP access to /goform/formPPPoESetup. Employ network-level protections such as firewalls or intrusion prevention systems to detect and block exploit attempts. Monitor network traffic for signs of exploitation. [2]
