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-2025-6146 is a critical buffer overflow vulnerability in the TOTOLINK X15 router firmware version 1.0.0-B20230714.1105. It occurs in the HTTP POST request handler at the endpoint /boafrm/formSysLog, specifically involving the submit-url parameter. The vulnerability arises because the router copies data from an input buffer 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 HTTP 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 X15 router. An attacker can remotely exploit the buffer overflow to cause denial of service (DoS), potentially disrupting network connectivity. Since the exploit requires no authentication or local access, it poses a high risk of unauthorized control or disruption of the device's normal operation. [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/formSysLog, 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 such requests. 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://<router_ip>/boafrm/formSysLog. Additionally, packet capture tools like tcpdump or Wireshark can be used to inspect traffic to this endpoint for malicious payloads. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the vulnerable endpoint /boafrm/formSysLog by implementing network-level controls such as firewall rules to block or limit HTTP POST requests to this path from untrusted sources. Since no known mitigations or patches are available, it is recommended to replace the affected TOTOLINK X15 device with an alternative product. Monitoring for exploit attempts and disabling remote management features if possible can also reduce risk. [2]
