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-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 stack-based buffer overflow found in the Tenda AC6 router firmware version 15.03.06.50. It occurs due to improper processing of the 'shareSpeed' argument in the HTTP Request Handler component at the /goform/WifiGuestSet endpoint. An attacker can remotely exploit this flaw by sending specially crafted requests, potentially leading to arbitrary code execution or system compromise. [2]
How can this vulnerability impact me? :
Exploitation of this vulnerability can allow a remote attacker to execute arbitrary code on the affected device, potentially leading to full control over the router. This can result in unauthorized access to the network, interception or manipulation of network traffic, disruption of network services, and further attacks on connected devices. [2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection of this vulnerability can involve monitoring HTTP requests to the /goform/WifiGuestSet endpoint for unusual or malformed shareSpeed parameter values that could trigger a stack-based buffer overflow. Using network traffic analysis tools like Wireshark or tcpdump to capture and inspect such requests may help. Additionally, reviewing logs for unexpected crashes or behavior related to the HTTP Request Handler component could indicate exploitation attempts. Specific commands might include using curl or wget to send crafted requests to /goform/WifiGuestSet to test for vulnerability, for example: curl -X POST http://<target-ip>/goform/WifiGuestSet -d "shareSpeed=<malicious_payload>". However, no exact detection commands are provided in the resources. [2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting remote access to the affected device, especially blocking access to the /goform/WifiGuestSet endpoint from untrusted networks. Applying any available firmware updates from the vendor (Tenda) that address this vulnerability is critical. If no patch is available, consider disabling the vulnerable service or isolating the device from the internet to prevent remote exploitation. Monitoring network traffic for suspicious activity targeting this endpoint is also recommended. [1, 2]
