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-2026-10162 is a stack-based buffer overflow vulnerability found in the TRENDnet TEW-432BRP router, specifically in the formSetPassword function accessed via the /goform/formSetPassword endpoint.
The vulnerability occurs because the input parameter 'webpage' is copied directly to a local stack variable without proper validation, allowing an attacker to overwrite the function's return address.
By sending a specially crafted POST request with a long string (for example, 870 'a' characters), an attacker can cause the router to crash and become unresponsive.
This issue arises from insufficient input sanitization in the password management form, and a proof-of-concept exploit has been published demonstrating the attack.
How can this vulnerability impact me? :
This vulnerability can cause the affected TRENDnet router to crash and become unresponsive, leading to denial of service.
Since the router fails to provide services correctly after exploitation, network connectivity and security functions relying on the device may be disrupted.
Because the product is end-of-life and no longer supported, there is no official fix available, increasing the risk of exploitation.
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/formSetPassword' endpoint with a long string (for example, 870 'a' characters) in the 'webpage' parameter. If the device crashes or becomes unresponsive, it indicates the presence of the vulnerability.
A detection command example using curl would be:
- curl -X POST -d "webpage=$(python3 -c 'print("a"*870)')" http://[target_ip]/goform/formSetPassword
If the device crashes or stops responding after this request, it is likely vulnerable to CVE-2026-10162.
What immediate steps should I take to mitigate this vulnerability?
Since the affected product TRENDnet TEW-432BRP 3.10B20 has been end-of-life (EOL) for 15 years and the vendor does not provide fixes, immediate mitigation steps include:
- Remove or isolate the vulnerable device from the network to prevent remote exploitation.
- Disable remote management or restrict access to the '/goform/formSetPassword' endpoint if possible.
- Replace the device with a supported and updated router model to ensure security patches and ongoing support.
Proper input sanitization is recommended but cannot be applied by end users due to lack of vendor support.
