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-2025-6163 is a critical buffer overflow vulnerability in the TOTOLINK A3002RU router (version 3.0.0-B20230809.1615). It occurs in the HTTP POST request handler at the endpoint /boafrm/formMultiAP, specifically when the submit-url argument is manipulated. The vulnerability arises because the router copies input data to an output buffer without checking if the input size exceeds the buffer size, causing a buffer overflow. This flaw can be exploited remotely by an attacker sending a crafted POST request. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing a remote attacker to perform a denial of service (DoS) attack on the affected router, potentially disrupting network availability. Additionally, it compromises the confidentiality, integrity, and availability of the device, meaning attackers could potentially execute arbitrary code or cause the device to behave unpredictably. The exploit requires no authentication and is publicly available, making it highly severe. [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 POST requests to the endpoint /boafrm/formMultiAP, specifically looking for requests that manipulate the submit-url argument with unusually large or malformed payloads that could trigger a buffer overflow. Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to alert on such suspicious POST requests. A simple detection command using curl to test the endpoint might be: curl -X POST http://<router-ip>/boafrm/formMultiAP -d "submit-url=<large_payload>". However, no specific detection commands or signatures are provided in the available resources. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected TOTOLINK A3002RU router with an alternative device, as no known countermeasures or patches currently exist. Additionally, restricting access to the device's management interface from untrusted networks and monitoring for suspicious POST requests to /boafrm/formMultiAP can help reduce risk until the device is replaced.
