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 FH451 version 1.0.0.9, specifically in the function formQuickIndex within the file /goform/QuickIndex. It involves manipulation of the argument mit_linktype/PPPOEPassword, which leads to a stack-based buffer overflow. This type of vulnerability allows an attacker to overwrite parts of the memory stack, potentially enabling arbitrary code execution.
The attack can be launched remotely, meaning an attacker does not need physical access to the device to exploit it. Additionally, a public exploit is available, increasing the risk of exploitation.
