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-2025-6164 is a critical buffer overflow vulnerability in the TOTOLINK A3002R router firmware version 4.0.0-B20230531.1404. It occurs in the HTTP POST request handler at the endpoint /boafrm/formMultiAP, specifically through manipulation of the submit-url parameter. The vulnerability arises because the device copies input data into a buffer without checking if the input size exceeds the buffer size, leading to a buffer overflow condition. This flaw can be exploited remotely by sending a crafted malicious POST request to the affected endpoint. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing an attacker to remotely exploit the buffer overflow to cause a denial of service (DoS) on the affected device, potentially disrupting network connectivity. It also impacts the confidentiality, integrity, and availability of the device, meaning attackers could compromise sensitive data, alter device behavior, or render the device unusable. There are no known mitigations, so the affected product should be replaced to avoid exploitation. [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 sent to the endpoint `/boafrm/formMultiAP` on the TOTOLINK A3002R router. Specifically, look for suspicious or unusually large payloads manipulating the `submit-url` parameter, which may indicate an attempt to exploit the buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such POST requests. 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 A3002R device with an alternative product, as no known countermeasures or patches are currently available. Additionally, restricting or blocking HTTP POST requests to the `/boafrm/formMultiAP` endpoint at the network perimeter or firewall may reduce exposure. Monitoring for exploit attempts and isolating vulnerable devices from untrusted networks are also recommended. [2]
