Exploitability
| CWE ID | Description |
|---|---|
| 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-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. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the Tenda AC9 router firmware version 15.03.06.42_multi, specifically in the function formGetRebootTimer.
It involves manipulation of the arguments sys.schedulereboot.start_time and sys.schedulereboot.end_time, which leads to 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 launched remotely, and the exploit has been publicly disclosed.
