The CVE-2017-6180 vulnerability affects Keekoon KK002 devices running firmware version 1.8.12 HD, presenting a critical cross site request forgery flaw that compromises the device's authentication and user management systems. This vulnerability specifically targets the web interface components responsible for handling user password changes and user management operations through the affected endpoints goform/formChnUserPwd and goform/formUserMng, which are part of the broader set of web pages accessible to authenticated users. The flaw stems from insufficient validation of request origins and lack of proper anti-CSRF token implementation within the device's web application framework, allowing malicious actors to craft forged requests that can be executed by authenticated users without their knowledge or consent.
The technical exploitation of this vulnerability occurs when an attacker crafts a malicious web page or email attachment that contains embedded requests to the vulnerable device's web interface. When an authenticated user visits the malicious page or clicks on a link, the browser automatically submits requests to the device's management interface without user interaction, potentially changing passwords or adding new user accounts. This type of attack leverages the trust relationship between the browser and the device, where the browser automatically includes authentication cookies in requests to the device, making it impossible for the device to distinguish between legitimate and malicious requests. The vulnerability is particularly dangerous because it can be exploited through social engineering techniques, where users are tricked into visiting malicious websites while maintaining active sessions with the device.
The operational impact of CVE-2017-6180 extends beyond simple unauthorized access, as it can lead to complete device compromise and persistent backdoor access. An attacker who successfully exploits this vulnerability can modify user accounts, escalate privileges, and potentially gain persistent access to the network infrastructure. The device's configuration management capabilities become compromised, allowing attackers to modify network settings, change administrator credentials, or disable security features. This vulnerability directly relates to CWE-352, which defines cross site request forgery flaws, and aligns with ATT&CK technique T1078.004 for valid accounts and T1566 for phishing, as the attack vector typically involves user interaction with malicious content. The vulnerability affects the device's integrity and availability, potentially disrupting network services and creating persistent security weaknesses that can be exploited for further attacks.
Mitigation strategies for CVE-2017-6180 should include immediate firmware updates from Keekoon to address the CSRF implementation flaws in the web interface. Network administrators should implement additional security controls such as disabling unnecessary web management interfaces, restricting access to the device through firewalls, and implementing network segmentation to limit the attack surface. Regular security assessments should be conducted to identify similar vulnerabilities in other network devices, particularly those with web-based management interfaces. The implementation of proper anti-CSRF token mechanisms, request origin validation, and session management controls should be enforced across all web applications. Organizations should also consider implementing network monitoring solutions to detect unusual patterns of device access and authentication attempts that may indicate exploitation attempts. Security awareness training for users should emphasize the dangers of visiting untrusted websites and clicking suspicious links, as social engineering remains a primary exploitation vector for this class of vulnerability.
