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-2025-7090 is a critical stack-based buffer overflow vulnerability in the Belkin F9K1122 router firmware version 1.00.33. It occurs in the function formConnectionSetting, where the parameters max_Conn and timeOut are taken from user input without proper validation. If these parameters contain data longer than expected, it causes a stack overflow, which can be exploited remotely to crash the device or execute arbitrary code. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing remote attackers to crash your Belkin F9K1122 router or execute arbitrary code on it. This compromises the confidentiality, integrity, and availability of the device, potentially leading to unauthorized access, disruption of network services, or further exploitation of your network. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection of this vulnerability involves monitoring for attempts to access or exploit the /goform/formConnectionSetting endpoint with crafted parameters max_Conn and timeOut that exceed expected lengths, potentially causing crashes or abnormal behavior. Network intrusion detection systems (NIDS) can be configured to alert on HTTP requests targeting /goform/formConnectionSetting with unusually long or malformed max_Conn/timeOut parameters. Specific commands are not provided in the resources, but using tools like curl or wget to test the endpoint with oversized parameters could help identify vulnerable devices. For example, a command to test might be: curl -X POST http://<router-ip>/goform/formConnectionSetting -d "max_Conn=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA&timeOut=BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB" and observe if the device crashes or behaves abnormally. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include discontinuing use of the affected Belkin F9K1122 router firmware version 1.00.33, as no patches or vendor responses are available. Consider replacing the affected device with a secure alternative. Additionally, restrict remote access to the router's web interface, especially blocking access to the /goform/formConnectionSetting endpoint from untrusted networks. Implement network-level protections such as firewalls or intrusion prevention systems to detect and block exploit attempts targeting this vulnerability. [2]
