CVE-2025-15472 is an OS command injection vulnerability identified in the TRENDnet TEW-811DRU wireless router, specifically version 1.0.2.0. The vulnerability resides in the setDeviceURL function of the uapply.cgi script, part of the device's embedded HTTP server (httpd). An attacker can remotely manipulate the DeviceURL parameter to inject arbitrary operating system commands, which the device executes with elevated privileges. This flaw does not require user interaction or authentication but does require the attacker to have high privileges, indicating that exploitation may be possible after initial access or through other means to elevate privileges. The vulnerability has a CVSS 4.0 base score of 8.6, reflecting its high severity due to network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability. Although the vendor was notified early, no patch or mitigation guidance has been released, and public exploit code is available, increasing the risk of exploitation. The vulnerability could allow attackers to fully compromise the device, execute arbitrary commands, disrupt network services, or use the device as a foothold for lateral movement within an organization's network.

For European organizations, exploitation of CVE-2025-15472 could lead to severe consequences including unauthorized control over network infrastructure devices, data exfiltration, disruption of network availability, and potential pivoting to other internal systems. Given that the affected device is a wireless router, compromise could undermine the security of connected endpoints and sensitive communications. Critical sectors such as government, finance, healthcare, and industrial operations relying on TRENDnet TEW-811DRU devices may face operational disruptions and data breaches. The lack of vendor response and patch availability increases the window of exposure, making timely detection and mitigation essential. Additionally, the presence of public exploit code lowers the barrier for attackers, including cybercriminals and state-sponsored actors targeting European entities. This vulnerability could also be leveraged in botnet formation or ransomware campaigns, amplifying its impact on European digital infrastructure.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include disabling remote management interfaces on the TEW-811DRU devices if not strictly necessary, restricting device management access to trusted internal networks only, and applying strict firewall rules to block unauthorized inbound traffic to the device's HTTP server. Network segmentation should isolate vulnerable devices from critical systems to limit lateral movement. Continuous monitoring for anomalous command execution or unexpected network traffic originating from these routers is crucial. Organizations should also consider replacing affected devices with updated hardware from vendors with active security support. Where possible, conducting internal penetration testing to identify exploitation attempts and educating IT staff about this vulnerability will enhance preparedness. Finally, organizations should maintain up-to-date asset inventories to identify all affected devices promptly.
