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-121 | A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-10063 is a stack-based buffer overflow vulnerability in the TRENDnet TEW-432BRP router, specifically in the formWPS function accessed via the /goform/formWPS endpoint.
The vulnerability occurs because the 'peerPin' parameter is copied to a stack-allocated variable without proper input validation or sanitization. An attacker can send a specially crafted POST request with an overly long 'peerPin' value, which overwrites the function's return address on the stack.
This causes the router to crash and become unresponsive, disrupting its services. The exploit is publicly available and can be performed remotely.
How can this vulnerability impact me? :
This vulnerability can cause the affected TRENDnet router to crash and become unresponsive, leading to a denial of service.
As the router stops functioning properly, network connectivity and related services relying on the device will be disrupted.
Since the exploit is publicly available and can be executed remotely, attackers can easily target vulnerable devices to cause service outages.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by sending a specially crafted POST request to the '/goform/formWPS' endpoint with an excessively long string in the 'peerPin' parameter. If the device is vulnerable, it will crash or become unresponsive.
A detection command example using curl would be:
- curl -X POST -d "peerPin=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" http://[router_ip]/goform/formWPS
If the router crashes or stops responding after this request, it indicates the presence of the vulnerability.
What immediate steps should I take to mitigate this vulnerability?
Since the affected product TRENDnet TEW-432BRP has been end-of-life for 15 years and no patches or fixes are available, immediate mitigation steps include:
- Discontinue use of the vulnerable device and replace it with a supported and updated router model.
- If replacement is not immediately possible, restrict remote access to the device, especially blocking access to the '/goform/formWPS' endpoint.
- Implement network-level protections such as firewall rules to prevent unauthorized POST requests targeting the vulnerable endpoint.
- Monitor the device for unusual crashes or unresponsiveness that may indicate exploitation attempts.
