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-2025-5910 is a critical buffer overflow vulnerability in the TOTOLINK EX1200T router firmware up to version 4.1.2cu.5232_B20210713. It occurs in the HTTP POST request handler at the endpoint /boafrm/formWsc, where the software copies input data to an output buffer without checking if the input size fits, causing a buffer overflow. This flaw can be exploited remotely by sending a specially crafted malicious POST request, potentially leading to 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 router. An attacker can remotely exploit the buffer overflow to cause denial of service (DoS), potentially disrupting network connectivity and device operation. Because the exploit is publicly available and easy to execute remotely, it poses a significant security risk to users of the affected firmware. [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/formWsc on TOTOLINK EX1200T devices running vulnerable firmware versions. Detection involves checking for unusual or malicious POST requests targeting this endpoint. Specific commands are not provided in the resources, but network monitoring tools or web application firewalls can be configured to log or alert on POST requests to /boafrm/formWsc. Additionally, reviewing HTTP logs for suspicious POST requests to this path may help identify exploitation attempts. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include avoiding the use of the affected TOTOLINK EX1200T firmware version up to 4.1.2cu.5232_B20210713. Since no known mitigations or patches are available, it is recommended to replace the affected product with an alternative device to prevent exploitation. Additionally, restricting or blocking HTTP POST requests to the /boafrm/formWsc endpoint via network controls or firewalls may reduce risk until a fix is available. [2]
