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 F451 device, specifically in the function fromSafeUrlFilter within the file /goform/SafeUrlFilter. It involves manipulation of the argument 'page' which leads to a stack-based buffer overflow. This type of vulnerability allows an attacker to overwrite parts of the memory stack, potentially leading to arbitrary code execution.
The attack can be performed remotely, meaning an attacker does not need physical access to the device to exploit it. Additionally, an exploit for this vulnerability is publicly available.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to severe impacts including unauthorized code execution on the affected device. Because it is a stack-based buffer overflow, an attacker could potentially take control of the device remotely.
- Remote code execution
- Potential full compromise of the device
- Disruption of device functionality or network services
