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-2025-6128 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/formWirelessTbl, specifically involving the submit-url parameter. The vulnerability arises because the device copies input data to a buffer without checking if the input size exceeds the buffer size, leading to a buffer overflow. This flaw can be exploited remotely 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 compromising the confidentiality, integrity, and availability of the affected TOTOLINK EX1200T device. An attacker can remotely exploit the buffer overflow to cause denial of service (DoS), potentially disrupting network connectivity or device operation. Because the exploit is publicly available and requires no authentication, it poses a significant risk to device security and network stability. [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/formWirelessTbl on TOTOLINK EX1200T devices running firmware version 4.1.2cu.5232_B20210713. Specifically, look for suspicious or unusually large payloads in the submit-url parameter that could trigger a buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on POST requests to this endpoint. As for commands, you can use tools like curl or wget to test the endpoint manually, for example: curl -X POST -d "submit-url=<large_payload>" http://<device_ip>/boafrm/formWirelessTbl. Additionally, monitoring device logs for crashes or reboots may indicate exploitation attempts. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the affected device's management interface from untrusted networks to prevent remote exploitation. Since no known countermeasures or patches are available, consider isolating or replacing the affected TOTOLINK EX1200T device running firmware 4.1.2cu.5232_B20210713. Monitoring for unusual device behavior such as crashes or denial of service conditions is also advised. Applying network-level protections like firewall rules to block malicious POST requests to /boafrm/formWirelessTbl can help reduce risk. [2]
