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. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the Tenda AC10U router firmware versions 15.03.06.48 and 15.03.06.49. It affects the function fromadvsetlanip in the /goform/AdvSetLanip component, specifically the POST Request Parameter Handler. By manipulating the lanMask argument, an attacker can cause a buffer overflow. This vulnerability can be exploited remotely, and a public exploit is available.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to a buffer overflow, which may allow an attacker to execute arbitrary code or cause a denial of service on the affected device. Since the attack can be launched remotely, it poses a significant security risk to the network and devices connected to the vulnerable router.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection can focus on monitoring POST requests to the endpoint /goform/AdvSetLanip, specifically looking for unusual or oversized lanMask parameter values that could trigger the buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such POST requests. However, no specific detection commands or signatures are provided in the available resources. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected Tenda AC10U devices running firmware versions 15.03.06.48 or 15.03.06.49, as no known countermeasures or patches currently exist. It is recommended to avoid exposing the device to untrusted networks and restrict access to the management interface to trusted users only until a fix or update is available. [2]
