Exploitability
| CWE ID | Description |
|---|---|
| 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. |
| 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-11293 is a critical buffer overflow vulnerability in the Belkin F9K1015 router version 1.00.10. It occurs in the /goform/formConnectionSetting endpoint, specifically through manipulation of the max_Conn parameter. Improper handling of this parameter allows an attacker to overflow a buffer by copying input data without verifying its size, which can lead to arbitrary code execution or denial of service on the router. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing a remote attacker to execute arbitrary code or cause a denial of service on your Belkin F9K1015 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 or testing access to the endpoint `/goform/formConnectionSetting` on the Belkin F9K1015 router version 1.00.10. Specifically, sending crafted requests manipulating the `max_Conn` parameter to check for buffer overflow behavior can help detect the issue. A proof-of-concept exploit is publicly available on GitHub at https://github.com/panda666-888/vuls/blob/main/belkin/f9k1015/formConnectionSetting.md, which can be used to test the vulnerability. Network scanning tools or custom scripts can be used to send HTTP POST requests to the vulnerable endpoint with varying `max_Conn` values to observe abnormal behavior or crashes. Example command using curl to test the endpoint might be: `curl -X POST http://<router-ip>/goform/formConnectionSetting -d "max_Conn=<value>"` where `<value>` is manipulated to trigger the overflow. [1]
What immediate steps should I take to mitigate this vulnerability?
No official mitigations or patches have been provided by the vendor Belkin. Immediate steps include restricting remote access to the affected router, especially blocking access to the `/goform/formConnectionSetting` endpoint from untrusted networks. Consider isolating the device from the internet or untrusted networks to prevent remote exploitation. Monitoring for unusual behavior or crashes can help detect exploitation attempts. Ultimately, it is recommended to replace the affected product with a secure alternative as no vendor response or fix is available. [2]
