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 is a security flaw found in the Tenda CX12L router firmware version 16.03.53.12. It exists in the function fromRouteStatic within the file /goform/RouteStatic. The issue arises from 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 causing unexpected behavior or allowing execution of malicious code.
How can this vulnerability impact me? :
The vulnerability can be exploited remotely without user interaction, allowing an attacker to cause a stack-based buffer overflow. This can lead to severe consequences such as executing arbitrary code, disrupting the normal operation of the device, or gaining unauthorized access. Because the exploit has been publicly released, the risk of attacks leveraging this vulnerability is increased.
