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-787 | The product writes data past the end, or before the beginning, of the intended buffer. |
| 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 critical stack-based buffer overflow found in the Tenda AC6 router firmware version 15.03.05.16. It occurs in the function formSetRebootTimer accessed via the /goform/SetRebootTimer endpoint. The issue arises from improper handling of the rebootTime argument, which can be manipulated remotely without authentication to overflow the stack. This overflow can lead to arbitrary code execution or denial of service on the affected device. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing remote attackers to execute arbitrary code or cause denial of service on your Tenda AC6 router. It affects the confidentiality, integrity, and availability of the device, potentially compromising your network security. Since the exploit is publicly available and easy to execute without authentication, it poses a significant risk. There are currently no known mitigations, so the recommended action is to replace the affected product to avoid exploitation. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection of this vulnerability involves monitoring or testing the /goform/SetRebootTimer endpoint for abnormal or malicious input targeting the rebootTime parameter. Since the vulnerability is a stack-based buffer overflow triggered by crafted rebootTime values, one could attempt to send specially crafted HTTP requests to this endpoint to see if the device behaves unexpectedly or crashes. Specific commands are not provided in the resources, but using tools like curl or custom scripts to send requests to http://<device-ip>/goform/SetRebootTimer with various rebootTime values could help detect exploitation attempts or vulnerability presence. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
There are no known countermeasures or mitigations currently available for this vulnerability. The recommended immediate step is to replace the affected Tenda AC6 device running firmware version 15.03.05.16 to avoid exploitation. Until a patch or fix is released, limiting network exposure of the device and monitoring for exploitation attempts may help reduce risk. [2]
