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-2026-10183 is a stack-based buffer overflow vulnerability found in the TRENDnet TEW-432BRP router, specifically in the formWlanSetup function accessed via the /goform/formWlanSetup endpoint.
The vulnerability occurs because the 'enrollee' parameter in an HTTP POST request is copied into a local stack variable without proper input validation or length checks.
An attacker can send a specially crafted long string to this parameter, which overwrites the function's return address on the stack, causing the router to crash and become unresponsive.
This exploit can be initiated remotely and a proof-of-concept is publicly available.
The product has been end-of-life for 15 years, and the vendor does not provide fixes or support for this vulnerability.
How can this vulnerability impact me? :
This vulnerability can cause the affected TRENDnet router to crash and become unresponsive, leading to denial of service.
As the router fails to provide services after exploitation, network connectivity and availability may be disrupted.
Since the exploit can be triggered remotely, attackers can cause service outages without physical access.
Because the product is no longer supported, there is no official fix, increasing the risk of prolonged exposure.
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 HTTP POST request to the endpoint /goform/formWlanSetup with the 'enrollee' parameter containing a long string of characters. If the device crashes or becomes unresponsive after this request, it indicates the presence of the vulnerability.
A simple detection command using curl could be:
- curl -X POST http://[router_ip]/goform/formWlanSetup -d "enrollee=$(python3 -c 'print("a"*1000)')"
If the router crashes or stops responding to requests after this command, it is vulnerable to the stack-based buffer overflow.
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 the vendor does not provide fixes or patches, immediate mitigation steps include:
- Discontinue use of the vulnerable device and replace it with a supported and updated router model.
- Isolate the vulnerable device from untrusted networks to prevent remote exploitation.
- Disable remote management features if enabled, to reduce exposure.
- Monitor network traffic for suspicious POST requests to /goform/formWlanSetup with unusually long 'enrollee' parameters.
