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). |
| CWE-787 | The product writes data past the end, or before the beginning, of the intended buffer. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the Tenda CH22 device, specifically in the function formCreateFileName within the file /goform/createFileName. It occurs when the argument fileNameMit is manipulated, leading to a stack-based buffer overflow. This type of vulnerability allows an attacker to overwrite parts of the memory stack, potentially causing the device to behave unexpectedly or execute malicious code.
The attack can be initiated remotely, meaning an attacker does not need physical access to the device to exploit this vulnerability. Additionally, the exploit code is publicly available, increasing the risk of exploitation.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to severe impacts including unauthorized code execution, device crashes, or denial of service. Since it is a stack-based buffer overflow, an attacker could potentially take control of the affected device remotely.
This could result in loss of device availability, compromise of device integrity, and unauthorized access to network resources connected to the device.
