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?
CVE-2025-7794 is a critical stack-based buffer overflow vulnerability in the Tenda FH451 router version 1.0.0.9. It exists in the function fromNatStaticSetting within the /goform/NatStaticSetting file. The vulnerability is caused by improper handling of the 'page' argument, which can be manipulated remotely without authentication to overflow the stack. This overflow can compromise the device's confidentiality, integrity, and availability, potentially allowing arbitrary code execution or denial of service. [1, 2]
How can this vulnerability impact me? :
This vulnerability can be exploited remotely to cause a stack-based buffer overflow, which may lead to arbitrary code execution or denial of service on the affected Tenda FH451 router. This means an attacker could take control of the device, disrupt its operation, or compromise the data it handles, impacting network security and device 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 or testing the /goform/NatStaticSetting endpoint on Tenda FH451 routers running firmware version 1.0.0.9, specifically by checking for abnormal behavior or crashes when the "page" parameter is manipulated. Since a proof-of-concept exploit is publicly available, penetration testing tools or custom scripts can be used to send crafted requests to this endpoint to verify if the device is vulnerable. However, no specific detection commands are provided in the available resources. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
No known mitigations or countermeasures have been identified for this vulnerability. It is recommended to consider replacing the affected product, the Tenda FH451 router running firmware version 1.0.0.9, to mitigate the risk. Additionally, restricting remote access to the device and monitoring for exploitation attempts may help reduce exposure until a fix or patch is available. [1]
