CVE-2025-15048 is a command injection vulnerability identified in the Tenda WH450 router firmware version 1.0.0.18. The vulnerability resides in the HTTP request handler component, specifically in the /goform/CheckTools endpoint. The issue arises from insufficient input validation or sanitization of the 'ipaddress' parameter, which allows an attacker to inject arbitrary shell commands. Because the HTTP handler processes this input without proper filtering, an attacker can remotely send crafted requests to execute commands on the underlying operating system of the device. The vulnerability requires no authentication or user interaction, making it remotely exploitable over the network. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low complexity, no privileges or user interaction required, and partial impact on confidentiality, integrity, and availability. Although no known exploits are currently active in the wild, the public disclosure of this vulnerability increases the likelihood of exploitation attempts. Successful exploitation could allow attackers to gain control over the router, manipulate network traffic, intercept sensitive data, or disrupt network services. The affected product, Tenda WH450, is a consumer and small business wireless router, which may be deployed in homes, small offices, and some enterprise edge environments. The lack of available patches or updates at the time of disclosure increases the urgency for mitigation measures.

The impact of CVE-2025-15048 is significant for organizations using Tenda WH450 routers, as exploitation enables remote command execution without authentication. This can lead to full compromise of the device, allowing attackers to manipulate network traffic, intercept or alter data, deploy malware, or create persistent backdoors. Confidentiality is at risk due to potential data interception or exfiltration. Integrity can be compromised by unauthorized changes to device configurations or network traffic. Availability may be affected if attackers disrupt router functionality or launch denial-of-service conditions. Organizations relying on these routers for critical network connectivity, especially in small office or home office environments, could face operational disruptions and increased exposure to lateral movement within internal networks. The medium CVSS score reflects the balance between ease of exploitation and partial impact on security properties. However, the lack of authentication and remote exploitability increase the threat level. The absence of known exploits in the wild currently limits immediate widespread impact, but the public disclosure may prompt attackers to develop and deploy exploits rapidly.

To mitigate CVE-2025-15048, organizations should immediately assess their network for the presence of Tenda WH450 routers running firmware version 1.0.0.18. Since no official patches are currently available, temporary mitigations include restricting access to the router's management interface by implementing network segmentation and firewall rules to block external and unauthorized internal access to the /goform/CheckTools endpoint. Disabling remote management features or restricting them to trusted IP addresses can reduce exposure. Monitoring network traffic for unusual requests targeting the vulnerable endpoint may help detect exploitation attempts. Organizations should contact Tenda support for firmware updates or advisories and apply patches as soon as they become available. Additionally, consider replacing vulnerable devices with models that have active security support. Implementing network intrusion detection systems (NIDS) with signatures for command injection attempts targeting this endpoint can provide early warnings. Regularly auditing router configurations and logs will help identify suspicious activities. Finally, educating users about the risks of exposed network devices and enforcing strong network security policies will reduce the attack surface.
