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 is a buffer overflow in the Tenda AC9 and AC15 routers' firmware versions 15.03.05.14 and 15.03.05.18. It occurs in the function 'formexeCommand' within the '/goform/exeCommand' endpoint, where the 'cmdinput' parameter is improperly handled. Specifically, the input buffer is copied to an output buffer without checking if the input size fits, leading to a buffer overflow. This flaw can be exploited remotely by sending specially crafted malicious packets, potentially causing the device to crash or be compromised. [1, 2]
How can this vulnerability impact me? :
Exploitation of this vulnerability can impact you by compromising the confidentiality, integrity, and availability of the affected Tenda AC9 and AC15 routers. An attacker can remotely execute the exploit to cause device crashes or potentially take control of the device, leading to disruption of network services, unauthorized access to sensitive data, or manipulation of device functions. [2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring network traffic for suspicious HTTP requests targeting the /goform/exeCommand endpoint with unusually large or malformed cmdinput parameters that could trigger a buffer overflow. Since the exploit is publicly available, you can use tools like curl or wget to send crafted requests to test if the device is vulnerable. For example, a command to test might be: curl -X POST http://<device-ip>/goform/exeCommand -d 'cmdinput=<malicious_payload>'. Additionally, network intrusion detection systems (NIDS) can be configured to alert on such suspicious requests to /goform/exeCommand with large payloads. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
There are no known patches or countermeasures available for this vulnerability at the time of disclosure. The recommended immediate mitigation is to replace the affected Tenda AC9 and AC15 devices running firmware versions 15.03.05.14 or 15.03.05.18 with alternative products. Additionally, restricting remote access to the device management interface and implementing network-level protections such as firewalls or access control lists to block unauthorized access to the /goform/exeCommand endpoint can help reduce exposure.
