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 stack-based buffer overflow in the Tenda AC21 router firmware version 16.03.08.16, specifically in the /goform/SetSysTimeCfg file. It occurs due to improper handling of the timeZone/time argument, allowing an attacker to remotely exploit the device by sending crafted input that overflows the stack buffer.
How can this vulnerability impact me? :
Exploiting this vulnerability can allow a remote attacker to execute arbitrary code on the affected device, potentially leading to full control over the router. This can result in disruption of network services, interception or manipulation of network traffic, and compromise of connected devices.
