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-120 | The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. |

Can you explain this vulnerability to me?
[{'type': 'paragraph', 'content': 'CVE-2026-3379 is a critical buffer overflow vulnerability found in the Tenda F453 router firmware version 1.0.0.3. It exists in the function fromSetIpBind within the file /goform/SetIpBind. The vulnerability occurs due to improper handling of the argument "page", where input is not properly size-checked before being copied from an input buffer to an output buffer. This leads to a classic buffer overflow condition, allowing an attacker to potentially overwrite memory and execute arbitrary code.'}, {'type': 'paragraph', 'content': 'The vulnerability can be exploited remotely without authentication, making it highly dangerous. It is classified under CWE-120 and CWE-119, which relate to improper buffer size handling.'}] [1, 3]
