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 AC8 router firmware version 16.03.34.09. It occurs in the function fromSetWirelessRepeat when the wpapsk_crypto parameter is manipulated with crafted input. This improper handling of input causes the stack buffer to overflow, which can lead to arbitrary code execution or denial of service on the affected device. The vulnerability can be exploited remotely without authentication, making it highly dangerous. [1, 2]
How can this vulnerability impact me? :
Exploitation of this vulnerability can compromise the confidentiality, integrity, and availability of the affected Tenda AC8 router. An attacker can remotely execute arbitrary code or cause the device to crash, leading to denial of service. Since the exploit is publicly available and requires no authentication, the risk of attack is significant, potentially allowing unauthorized control over the device and disruption of network services. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
There are no known mitigations currently available for this vulnerability. The recommended immediate step is to replace the affected Tenda AC8 router running firmware version 16.03.34.09 with a secure version or different device to avoid exploitation. [2]
