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 fromwebExcptypemanFilter located in the file /goform/webExcptypemanFilter. It involves a stack-based buffer overflow that can be triggered by manipulating the argument 'page'.
An attacker must have access to the local network to exploit this vulnerability. The exploit has been publicly disclosed, meaning details on how to carry out the attack are available.
How can this vulnerability impact me? :
Exploiting this vulnerability can lead to a stack-based buffer overflow, which may allow an attacker to execute arbitrary code or cause a denial of service on the affected device.
Since the attack requires local network access, an attacker within the same network could potentially compromise the device, leading to loss of confidentiality, integrity, and availability.
