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?
CVE-2025-11300 is a critical buffer overflow vulnerability in the Belkin F9K1015 router firmware version 1.00.10. It occurs in an unknown function within the file /goform/formWlanMP when the argument ateFunc is manipulated. This causes a buffer overflow due to improper input size handling, allowing an attacker to potentially execute arbitrary code or cause a denial of service by sending specially crafted input remotely. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by compromising the confidentiality, integrity, and availability of the affected device. An attacker can remotely exploit the buffer overflow to execute arbitrary code or cause a denial of service, potentially taking control of the router or disrupting its operation. There are currently no known patches or countermeasures, so the affected device should be replaced to mitigate risk. [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/formWlanMP for suspicious or unusually large values in the ateFunc argument that could trigger a buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such requests. Additionally, manual testing or scanning can be done by sending crafted HTTP requests to this endpoint to check for abnormal behavior or crashes. Specific commands could include using curl or wget to send test requests, for example: curl -X POST http://<router-ip>/goform/formWlanMP -d "ateFunc=<large_payload>" to observe the device's response. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected Belkin F9K1015 router with a different device, as no patches or vendor-provided fixes are currently available. Additionally, restricting remote access to the router's management interface, such as blocking HTTP access to /goform/formWlanMP from untrusted networks, can reduce exposure. Network-level protections like firewalls or intrusion prevention systems should be configured to detect and block exploit attempts targeting this endpoint. [2]
