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?
This vulnerability is a critical buffer overflow found in the TOTOLINK X15 router (version 1.0.0-B20230714.1105). It occurs in the HTTP POST request handler at the /boafrm/formSaveConfig endpoint. Specifically, the vulnerability arises from improper handling of the 'submit-url' parameter, where input data is copied without verifying its size, leading to a buffer overflow. An attacker can exploit this remotely by sending a specially crafted POST request, potentially causing 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 device. An attacker can remotely exploit the buffer overflow to cause denial of service or potentially execute arbitrary code, leading to device malfunction or takeover. Since no mitigations are currently known, the affected device is at high risk until replaced or patched. [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/formSaveConfig on the TOTOLINK X15 router version 1.0.0-B20230714.1105. Specifically, look for suspicious or unusually large 'submit-url' parameters in POST requests that could trigger the buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on POST requests to this endpoint. Additionally, you can use tools like curl or wget to test the endpoint manually by sending crafted POST requests to see if the device behaves abnormally or crashes. Example command to test the endpoint: curl -X POST http://<router-ip>/boafrm/formSaveConfig -d "submit-url=AAAA..." (with a large payload in submit-url). [1, 2]
What immediate steps should I take to mitigate this vulnerability?
There are no known mitigations or patches currently available for this vulnerability. The recommended immediate step is to replace the affected TOTOLINK X15 router version 1.0.0-B20230714.1105 with a non-vulnerable device. Additionally, restrict remote access to the router's management interface to trusted networks only, and monitor network traffic for exploitation attempts. Applying network-level protections such as firewall rules to block unauthorized POST requests to /boafrm/formSaveConfig can help reduce risk until replacement is possible. [2]
