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-2025-6162 is a critical buffer overflow vulnerability in the TOTOLINK EX1200T router firmware version 4.1.2cu.5232_B20210713. It occurs in the HTTP POST request handler at the endpoint /boafrm/formMultiAP, specifically when the submit-url parameter is manipulated. The vulnerability arises because the router copies input data to an output buffer without checking the input size, leading to a buffer overflow. This flaw can be exploited remotely without authentication by sending a specially crafted POST request, potentially causing denial of service or other impacts. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing a remote attacker to exploit the buffer overflow to cause denial of service (DoS) on the affected TOTOLINK EX1200T router. It compromises the confidentiality, integrity, and availability of the device. Since the exploit requires no authentication and is publicly available, it poses a high risk of being used to disrupt network operations or potentially gain further unauthorized access. [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 suspicious or unusually large submit-url parameter values that could trigger the buffer overflow. Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to alert on POST requests to this path. As for commands, you can use tools like curl or wget to test the endpoint manually, for example: curl -X POST http://<target-ip>/boafrm/formMultiAP -d "submit-url=<test_payload>". Additionally, network traffic capture tools like tcpdump or Wireshark can be used to filter and inspect POST requests to /boafrm/formMultiAP. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected TOTOLINK EX1200T device running firmware version 4.1.2cu.5232_B20210713 with an alternative product, as no known mitigations or patches are currently available. Additionally, restricting or blocking HTTP POST requests to the /boafrm/formMultiAP endpoint via firewall rules or network segmentation can reduce exposure. Monitoring and alerting on suspicious POST requests to this endpoint is also recommended to detect exploitation attempts. [2]
