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-2025-6165 is a critical buffer overflow vulnerability in the TOTOLINK X15 router version 1.0.0-B20230714.1105. It occurs in the HTTP POST request handler at the endpoint `/boafrm/formTmultiAP`, specifically involving the `submit-url` parameter. The vulnerability arises because the device copies input data to an output buffer without checking if the input size fits, leading to a buffer overflow. This flaw can be exploited remotely without authentication by sending a specially crafted HTTP POST request, potentially causing denial of service or other impacts. [1, 2]
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to denial of service (DoS) on the affected device, and potentially compromise the confidentiality, integrity, and availability of the router. Since the attack can be performed remotely without authentication, an attacker could disrupt network operations or gain further control over the device, impacting network security and reliability. [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 for HTTP POST requests to the endpoint `/boafrm/formTmultiAP` that include the `submit-url` parameter with unusually large or malformed input that could trigger a buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such suspicious POST requests. Additionally, you can use tools like curl or wget to manually test the endpoint by sending crafted POST requests to see if the device behaves abnormally or crashes. Example command to test the endpoint: `curl -X POST http://<router-ip>/boafrm/formTmultiAP -d "submit-url=$(python3 -c 'print("A"*1000)')"` to send a large payload in the submit-url parameter and observe the device response. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected TOTOLINK X15 router with an alternative device, as no official patch or fix is currently available. Additionally, restrict network access to the vulnerable device by limiting exposure to untrusted networks, such as placing the device behind a firewall or VPN, and monitoring for suspicious POST requests to the `/boafrm/formTmultiAP` endpoint. Disabling remote management or HTTP POST access to this endpoint, if possible, may also reduce risk. [2]
