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 stack-based buffer overflow found in the Tenda CX12L device, specifically in the function fromNatStaticSetting within the file /goform/NatStaticSetting. It occurs due to improper handling or manipulation of the argument 'page', which allows an attacker to overflow the buffer on the stack.
The vulnerability can be exploited remotely, meaning an attacker does not need physical access to the device to initiate an attack.
The exploit code for this vulnerability has been made publicly available, increasing the risk of attacks.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to a stack-based buffer overflow, which may allow an attacker to execute arbitrary code on the affected device.
This can result in unauthorized control over the device, potentially leading to disruption of network services, data compromise, or further attacks within the network.
Since the attack can be performed remotely, it increases the risk of unauthorized access without physical presence.
