CVE-2025-7083 is a security vulnerability identified in the Belkin F9K1122 router, specifically version 1.00.33. The flaw exists in the web interface component, within the /goform/mp endpoint, where the 'command' argument is improperly sanitized, leading to an OS command injection vulnerability. This means an attacker can remotely send crafted requests to the vulnerable endpoint and execute arbitrary operating system commands on the device with the privileges of the web service process. The vulnerability does not require user interaction and can be exploited over the network without authentication, increasing its risk profile. Although the CVSS 4.0 score is 5.3 (medium severity), the ability to execute OS commands remotely without authentication typically elevates the threat level. The vendor, Belkin, was contacted but did not respond or provide a patch, and no official fixes are currently available. There are no known exploits in the wild yet, but public disclosure of the exploit code increases the likelihood of future attacks. The vulnerability affects the firmware version 1.00.33 of the F9K1122 model, which is a consumer-grade router commonly used in home and small office environments. The lack of vendor response and patch availability means affected devices remain vulnerable, potentially allowing attackers to compromise network integrity, intercept or manipulate traffic, or use the device as a foothold for further attacks within a network.

For European organizations, especially small businesses and home offices relying on Belkin F9K1122 routers, this vulnerability poses a significant risk. Successful exploitation could lead to full compromise of the router, allowing attackers to intercept sensitive data, disrupt network availability, or pivot to internal systems. This could result in data breaches, loss of confidentiality, and potential disruption of business operations. Given the router’s role as a network gateway, attackers could also deploy persistent malware or launch further attacks on connected devices. The medium CVSS score may underestimate the real-world impact due to the lack of authentication and remote exploitability. Organizations with limited IT security resources may be particularly vulnerable, as they might not monitor or update consumer-grade network equipment regularly. Additionally, the absence of a vendor patch increases the window of exposure. The public availability of exploit details further elevates the risk of opportunistic attacks targeting European networks using this device.

1. Immediate mitigation should include isolating the affected Belkin F9K1122 routers from critical network segments to limit potential damage. 2. Replace or upgrade the router firmware if and when Belkin releases a patch; until then, consider replacing the device with a more secure alternative from a vendor with active security support. 3. Restrict remote access to the router’s management interface by disabling remote administration features or limiting access to trusted IP addresses only. 4. Implement network segmentation to ensure that compromised devices cannot easily access sensitive internal resources. 5. Monitor network traffic for unusual activity originating from or targeting the router, including unexpected outbound connections or command execution attempts. 6. Educate users about the risks of using outdated consumer-grade network devices and encourage regular updates and security hygiene. 7. If possible, deploy intrusion detection/prevention systems (IDS/IPS) that can detect exploitation attempts targeting this vulnerability. 8. Maintain an inventory of network devices to quickly identify and remediate vulnerable hardware.
