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.

Executive Summary

CVE-2025-11297 is a critical buffer overflow vulnerability in the Belkin F9K1015 router (version 1.00.10). It occurs in an unknown function within the file /goform/formSetLanguage due to improper handling of the 'webpage' argument. Specifically, input data is copied from an input buffer to an output buffer without verifying that the input size fits, leading to a buffer overflow. This flaw can be exploited remotely by an attacker to compromise the device. [1, 2]

Impact Analysis

This vulnerability can be exploited remotely to trigger a buffer overflow, potentially allowing an attacker to execute arbitrary code or cause a denial of service on the affected router. This compromises the device's confidentiality, integrity, and availability, leading to serious security risks. [1, 2]

Detection Guidance

This vulnerability can be detected by monitoring HTTP requests to the endpoint `/goform/formSetLanguage` on Belkin F9K1015 routers version 1.00.10. Since the exploit involves manipulation of the 'webpage' argument causing a buffer overflow, detection can involve inspecting HTTP traffic for unusual or oversized payloads targeting this endpoint. Specific commands are not provided in the resources, but network administrators can use tools like curl or wget to send crafted requests to `/goform/formSetLanguage` to test for vulnerability, or use network monitoring tools to detect suspicious requests. For example, a curl command to test might be: `curl -X POST http://<router-ip>/goform/formSetLanguage -d "webpage=..."` with a large payload in 'webpage'. However, no exact detection commands are detailed in the provided resources. [1, 2]

Mitigation Strategies

There are no known patches or vendor mitigations available for this vulnerability as the vendor did not respond to the disclosure. The recommended immediate step is to replace the affected Belkin F9K1015 router version 1.00.10 with an alternative device that is not vulnerable. Additionally, restricting remote access to the router's management interface and monitoring for exploit attempts can help reduce risk until replacement is possible. [1]
