CVE-2025-11665 is an OS command injection vulnerability identified in the D-Link DAP-2695 wireless access point firmware version 2.00RC131. The vulnerability resides in the fwupdater_main function within the firmware update handler component, specifically in the file named rgbin. An attacker can remotely manipulate the firmware update process to inject arbitrary operating system commands, potentially gaining control over the device. The attack vector requires no user interaction and no authentication, making it remotely exploitable over the network. However, the vulnerability only affects devices that are no longer supported by D-Link, meaning no official patches or firmware updates are available. The CVSS 4.0 base score of 5.1 indicates a medium severity, with network attack vector, low complexity, no privileges required, and no user interaction needed. The impact on confidentiality, integrity, and availability is low to limited, as the vulnerability scope is local to the device and does not propagate to other systems directly. No known exploits have been reported in the wild, but the potential for exploitation exists given the nature of the flaw. The vulnerability highlights risks associated with legacy network infrastructure and unsupported hardware in enterprise environments.

For European organizations, the impact of CVE-2025-11665 is primarily related to the compromise of network access points running the affected D-Link DAP-2695 firmware. Successful exploitation could allow attackers to execute arbitrary commands on the device, potentially leading to unauthorized network access, interception or manipulation of network traffic, and disruption of wireless services. This could affect business continuity and data confidentiality within the local network segment. Since the device is no longer supported, organizations cannot rely on vendor patches, increasing the risk if these devices remain in operation. Critical sectors such as government, finance, and telecommunications that may still use legacy D-Link equipment could face targeted attacks aiming to exploit this vulnerability. However, the limited scope and medium severity reduce the likelihood of widespread impact. The absence of known exploits in the wild currently lowers immediate risk but does not eliminate future threats.

Given the lack of vendor support and absence of patches, European organizations should prioritize the following mitigations: 1) Identify and inventory all D-Link DAP-2695 devices running firmware version 2.00RC131 or earlier. 2) Immediately isolate these devices on segmented network zones with strict access controls to limit exposure. 3) Replace unsupported DAP-2695 units with modern, supported wireless access points that receive regular security updates. 4) Implement network monitoring to detect anomalous command execution or firmware update attempts on these devices. 5) Disable remote firmware update functionality if possible or restrict it to trusted management networks. 6) Employ network-level protections such as firewalls and intrusion detection/prevention systems to block unauthorized access to the device management interfaces. 7) Educate IT staff about the risks of legacy device usage and enforce policies to phase out unsupported hardware. These steps go beyond generic advice by focusing on compensating controls and device lifecycle management.
