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-2025-5738 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 /boafrm/formStats endpoint, where improper handling of the 'submit-url' argument allows an attacker to overflow a buffer by sending a specially crafted POST request. This leads to memory corruption and can cause denial of service or other unpredictable behavior 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 device. An attacker can remotely exploit the flaw without authentication, potentially causing denial of service or executing arbitrary code. This can disrupt network operations, lead to device malfunction, or allow further attacks on your network infrastructure. [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/formStats on the TOTOLINK X15 router firmware version 1.0.0-B20230714.1105. Specifically, look for suspicious or unusually large 'submit-url' arguments 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, manual testing can be performed by crafting a POST request with a large payload in the 'submit-url' parameter to see if the device behaves abnormally or crashes. Example command using curl to test the endpoint: curl -X POST -d "submit-url=$(python3 -c 'print("A"*1000)')" http://<router-ip>/boafrm/formStats [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected TOTOLINK X15 router firmware version 1.0.0-B20230714.1105 with a patched or updated version if available. Since no known countermeasures or mitigations currently exist, it is recommended to isolate the vulnerable device from untrusted networks to prevent remote exploitation. Additionally, restrict access to the router's web interface and monitor for suspicious activity targeting the /boafrm/formStats endpoint. If possible, disable remote management features until a fix is applied. [2]
