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-122 | A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a heap-based buffer overflow in the Tenda M3 firmware version 1.0.0.13(4903), specifically in the function formSetAdInfoDetails of the file /goform/setAdInfoDetail. It occurs when certain arguments such as adName, smsPassword, smsAccount, weixinAccount, weixinName, smsSignature, adRedirectUrl, adCopyRight, smsContent, or adItemUID are manipulated. The flaw can be exploited remotely and the exploit code has been publicly released.
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to a heap-based buffer overflow, which may allow an attacker to execute arbitrary code remotely, potentially compromising the affected device. This can result in unauthorized access, data theft, device control, or disruption of service.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for suspicious POST requests sent to the /goform/setAdInfoDetail endpoint with crafted parameters such as adName, smsPassword, smsAccount, weixinAccount, weixinName, smsSignature, adRedirectUrl, adCopyRight, smsContent, or adItemUID that may trigger a heap-based buffer overflow. Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to alert on such anomalous POST requests. Specific commands are not provided in the resources, but capturing HTTP traffic with tools like tcpdump or Wireshark and filtering for POST requests to /goform/setAdInfoDetail could help detect exploitation attempts.

What immediate steps should I take to mitigate this vulnerability?
No known mitigations or countermeasures currently exist for this vulnerability. The recommended immediate step is to replace the affected Tenda M3 router running firmware version 1.0.0.13(4903) with a secure alternative to avoid risk. Additionally, restricting remote access to the device and monitoring for exploit attempts may help reduce exposure until replacement. [3]
