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 critical buffer overflow found in the Tenda AC5 router firmware version 15.03.06.47, specifically in the function formSetPPTPUserList located at /goform/setPptpUserList. It occurs because the function copies input data to a buffer without checking if the input size exceeds the buffer size, leading to a buffer overflow. This flaw can be exploited remotely and allows attackers to execute arbitrary code or cause a denial of service. [1, 2]
How can this vulnerability impact me? :
Exploitation of this vulnerability can compromise the confidentiality, integrity, and availability of the affected device. An attacker can remotely execute arbitrary code or cause a denial of service, potentially taking control of the router or disrupting its operation. There are no known mitigations, so affected users are advised to replace the product to avoid risk. [1, 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 requests to the endpoint /goform/setPptpUserList on Tenda AC5 routers running firmware version 15.03.06.47. Since the exploit involves sending specially crafted input to the formSetPPTPUserList function, inspecting HTTP POST requests targeting this endpoint for unusual or oversized 'list' parameters may indicate exploitation attempts. Specific commands are not provided in the resources. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected Tenda AC5 router firmware version 15.03.06.47 with an alternative product, as no known countermeasures or mitigations currently exist. Additionally, restricting remote access to the router's management interface and monitoring for suspicious activity targeting /goform/setPptpUserList may reduce risk until replacement is possible. [2]
