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-2025-6130 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 /boafrm/formStats endpoint, where the device copies input data to an output buffer without checking if the input size fits, 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 on the device. [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. Since the exploit requires no authentication and is publicly available, it poses a significant risk if the device remains unpatched. [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 for HTTP POST requests sent to the /boafrm/formStats endpoint on TOTOLINK EX1200T devices running firmware version 4.1.2cu.5232_B20210713. You can use network traffic analysis tools like tcpdump or Wireshark to filter for POST requests to this specific path. For example, a tcpdump command to capture such traffic could be: tcpdump -i <interface> 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0) and (tcp[((tcp[12]&0xf0)>>2):4] = 0x504f5354)' and then filter for /boafrm/formStats in the HTTP payload. Additionally, checking web server logs on the device for POST requests to /boafrm/formStats can help detect attempts to exploit this vulnerability. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting network access to the affected TOTOLINK EX1200T device, especially blocking or filtering HTTP POST requests to the /boafrm/formStats endpoint. Since no official patch or fix is available, it is recommended to replace the affected device with an alternative product to avoid exploitation. Additionally, monitoring for exploit attempts and isolating vulnerable devices from untrusted networks can reduce risk. [2]
