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-2025-5736 is a critical buffer overflow vulnerability in the TOTOLINK X15 router (version 1.0.0-B20230714.1105). It occurs in the HTTP POST request handler at the endpoint /boafrm/formNtp, where the submit-url argument is manipulated. The vulnerability happens because the device copies input data into a buffer without checking if the input size exceeds the buffer size, causing a buffer overflow (CWE-120). This flaw can be exploited remotely without authentication. [1]
How can this vulnerability impact me? :
This vulnerability can severely impact the confidentiality, integrity, and availability of the affected system. An attacker can remotely exploit the buffer overflow to execute arbitrary code, potentially taking control of the device, disrupting its operation, or stealing sensitive information. Since there are no known mitigations or patches, the affected device remains at high risk until replaced or secured. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection can be performed by monitoring HTTP POST requests to the endpoint /boafrm/formNtp and inspecting the submit-url argument for unusually large or malformed input that could trigger a buffer overflow. Since a public proof-of-concept exploit is available, network intrusion detection systems (NIDS) can be configured with signatures matching the exploit payload. Specific commands are not provided in the resources, but using tools like curl or wget to send crafted POST requests to /boafrm/formNtp with varying submit-url values may help verify vulnerability presence. [1]
What immediate steps should I take to mitigate this vulnerability?
No known countermeasures or mitigations have been identified for this vulnerability. The recommended immediate step is to replace the affected TOTOLINK X15 1.0.0-B20230714.1105 device with an alternative product to avoid exploitation. [1]
