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 flaw in the Tenda AC23 router firmware version 16.03.07.52. It occurs in the handling of the wpapsk_crypto argument within the /goform/WifiExtraSet interface. The router improperly processes input data without verifying its size, causing a buffer overflow. This flaw can be exploited remotely by sending a crafted HTTP POST request to the vulnerable endpoint, potentially leading to abnormal behavior such as crashes or denial of service. [2, 3]
How can this vulnerability impact me? :
Exploitation of this vulnerability can cause a Denial of Service (DoS) attack on the Tenda AC23 router, making the device unresponsive or causing it to crash. Additionally, it impacts the confidentiality, integrity, and availability of the device, potentially allowing attackers to disrupt network connectivity or compromise device functions remotely. [2, 3]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for malicious HTTP POST requests targeting the /goform/WifiExtraSet endpoint, specifically those manipulating the wpapsk_crypto parameter. Network intrusion detection systems (NIDS) can be configured to alert on unusual or malformed POST requests to this path. Additionally, inspecting router logs for crashes or unresponsiveness after such requests may indicate exploitation attempts. Specific commands are not provided in the resources, but using tools like curl to send crafted POST requests to /goform/WifiExtraSet can help test for vulnerability presence. [2, 3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected Tenda AC23 router firmware version 16.03.07.52 with an alternative device or firmware, as no known countermeasures or patches currently exist. Limiting remote access to the router's management interface and implementing network-level protections such as firewalls or access control lists to block unauthorized HTTP POST requests to /goform/WifiExtraSet can reduce exposure. Monitoring for exploit attempts and disabling remote management if possible are also recommended. [3, 2]
