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?
CVE-2025-10120 is a buffer overflow vulnerability in the Tenda AC20 router firmware up to version 16.03.08.12. It occurs in the strcpy function within the /goform/GetParentControlInfo file, where the 'mac' argument is not properly validated for size, allowing an attacker to overflow the buffer. This flaw can be exploited remotely by sending a specially crafted HTTP POST request, potentially leading to denial of service or remote code execution on the device. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing an attacker to remotely exploit the Tenda AC20 router, leading to denial of service (DoS) or remote code execution (RCE). This means the attacker could disrupt the router's operation or take control of the device, compromising its confidentiality, integrity, and availability. [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 for suspicious HTTP POST requests to the endpoint /goform/GetParentControlInfo containing unusually long or malformed 'mac' arguments that could trigger the buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such requests. Additionally, manual inspection or automated scanning tools can be used to send crafted requests to test if the device is vulnerable. 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 AC20 router or upgrading its firmware to a version later than 16.03.08.12 if available. Since no known mitigations or countermeasures have been identified, restricting remote access to the device and monitoring for exploit attempts are recommended until a patch or update is applied. [2]
