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 critical stack-based buffer overflow in the Tenda O3V2 1.0.0.12(3880) device. It occurs in the function formWifiBasicSet within the /goform/setWrlBasicInfo component of the httpd service. The issue arises from improper handling of the extChannel argument, which can be manipulated remotely to overflow the stack buffer, potentially allowing an attacker to execute arbitrary code or cause a denial of service.
How can this vulnerability impact me? :
The vulnerability can be exploited remotely to cause a stack-based buffer overflow, which may allow an attacker to execute arbitrary code, disrupt device functionality, or cause a denial of service. This could lead to unauthorized control over the affected device and compromise network security.
