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 F451 device running version 1.0.0.7_cn_svn7958. It exists in the function fromqossetting within the file /goform/qossetting. By manipulating the argument 'qos', an attacker can cause a stack-based buffer overflow.
This type of vulnerability allows an attacker to potentially execute arbitrary code or cause a denial of service by overflowing the buffer on the stack.
The attack can be performed remotely, meaning an attacker does not need physical access to the device to exploit this flaw.
Additionally, the exploit code for this vulnerability has been publicly released, increasing the risk of attacks.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to serious impacts including remote code execution, which allows an attacker to take control of the affected device.
It can also cause denial of service conditions by crashing the device through the buffer overflow.
Since the attack can be carried out remotely and the exploit is publicly available, the risk of compromise is significant if the device is exposed to untrusted networks.
