CVE-2025-12296 is an OS command injection vulnerability identified in the D-Link DAP-2695 wireless access point firmware version 2.00RC13. The vulnerability resides in the Firmware Update Handler component, specifically within the function sub_4174B0. An attacker can remotely exploit this flaw by manipulating input parameters to inject arbitrary operating system commands, potentially gaining control over the device or executing malicious code. The attack vector requires no user interaction and no authentication, making it accessible to remote attackers over the network. However, the vulnerability has a limited scope of impact on confidentiality, integrity, and availability, as indicated by the CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L). The vulnerability is rated medium severity with a CVSS score of 5.1. Importantly, the affected product is no longer supported by D-Link, and no official patches or updates are available, increasing the risk for organizations still operating these devices. While no known exploits have been observed in the wild yet, the public disclosure of the vulnerability and availability of technical details raise the likelihood of future exploitation attempts. The vulnerability could allow attackers to compromise network devices, potentially leading to lateral movement, data interception, or disruption of network services.

For European organizations, the impact of CVE-2025-12296 can be significant if D-Link DAP-2695 devices remain in use, especially in critical network segments. Successful exploitation could lead to unauthorized command execution on network access points, compromising device integrity and potentially allowing attackers to pivot into internal networks. This could result in data breaches, disruption of wireless connectivity, and degradation of network availability. Since the product is no longer supported, organizations cannot rely on vendor patches, increasing exposure. Industries with high reliance on wireless infrastructure, such as manufacturing, healthcare, and government, may face elevated risks. Additionally, compromised devices could be used as entry points for broader attacks, impacting confidentiality and operational continuity. The medium severity rating reflects moderate impact but ease of exploitation without authentication, which is concerning for environments with limited device management or outdated inventories.

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 2.00RC13 or earlier. 2) Immediately plan for device replacement with supported hardware to eliminate the vulnerability. 3) Until replacement, isolate affected devices on segmented network zones with strict access controls to limit exposure. 4) Employ network intrusion detection systems (NIDS) to monitor for suspicious command injection patterns or anomalous device behavior. 5) Disable remote firmware update functionality if possible or restrict it to trusted management networks. 6) Harden device configurations by disabling unnecessary services and enforcing strong administrative credentials. 7) Conduct regular security audits and vulnerability assessments focusing on legacy network equipment. 8) Educate network administrators about the risks and signs of exploitation related to this vulnerability. These steps go beyond generic advice by focusing on compensating controls and proactive device lifecycle management in the absence of patches.
