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?
This vulnerability exists in the Tenda CX12L device, specifically in the function fromAddressNat within the file /goform/addressNat. It is caused by improper handling of the argument 'page', which leads to a stack-based buffer overflow. This means that an attacker can send specially crafted input remotely to overflow the buffer on the stack, potentially allowing them to execute arbitrary code or cause the device to crash.
How can this vulnerability impact me? :
The vulnerability can be exploited remotely without user interaction, which makes it particularly dangerous. Successful exploitation could allow an attacker to execute arbitrary code on the affected device, leading to potential full compromise. This could result in denial of service, unauthorized access, or control over the device.
