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-2025-6148 is a critical buffer overflow vulnerability in the TOTOLINK A3002RU router (version 3.0.0-B20230809.1615). It occurs in the HTTP POST request handler at the endpoint /boafrm/formSysLog, specifically involving the submit-url parameter. The vulnerability arises because the device copies input data to an output buffer without verifying that the input size fits, leading to a buffer overflow condition. This flaw allows remote attackers to exploit the device without authentication. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by compromising the confidentiality, integrity, and availability of the affected device. An attacker can remotely exploit the buffer overflow to potentially execute arbitrary code or cause a denial of service (DoS), disrupting normal device operation and possibly gaining unauthorized control over the router. [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 to the endpoint /boafrm/formSysLog with the submit-url parameter. Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to alert on such requests. Additionally, you can use tools like curl or wget to test the endpoint manually by sending crafted POST requests to /boafrm/formSysLog and observing the response or any abnormal behavior. For example, a command to test might be: curl -X POST http://<router-ip>/boafrm/formSysLog -d "submit-url=<test>". However, no specific detection commands or signatures are provided in the resources. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected TOTOLINK A3002RU router running version 3.0.0-B20230809.1615 with an alternative device, as no known countermeasures or patches are available. Additionally, restricting remote access to the router's management interface, disabling remote HTTP access if possible, and monitoring for suspicious POST requests to /boafrm/formSysLog can help reduce exposure. Since the vulnerability can be exploited remotely without authentication, limiting network exposure is critical. [1]
