CVE-2017-8407 in DCS-1130
Summary
by MITRE
An issue was discovered on D-Link DCS-1130 devices. The device provides a user with the capability of changing the administrative password for the web management interface. It seems that the device does not implement any cross-site request forgery protection mechanism which allows an attacker to trick a user who is logged in to the web management interface to change the user's password.

The vulnerability identified as CVE-2017-8407 affects D-Link DCS-1130 security cameras and represents a critical cross-site request forgery flaw that undermines the device's web-based management interface security. This issue specifically targets the administrative password change functionality, which lacks proper CSRF protection mechanisms that should prevent unauthorized password modifications. The vulnerability exists within the device's web server implementation and demonstrates a fundamental failure in web application security controls that directly impacts the integrity and confidentiality of the device's administrative access.
The technical flaw manifests through the absence of anti-CSRF tokens or mechanisms that validate the origin of password change requests submitted to the D-Link DCS-1130 web interface. When an authenticated user accesses the device's management interface, the system should verify that any password modification requests originate from legitimate sources within the same session. Without this protection, an attacker can craft malicious web pages or send targeted links that automatically submit password change requests to the vulnerable device when a logged-in user visits the malicious content. This allows the attacker to silently modify the administrative credentials without requiring authentication or knowledge of the current password, effectively hijacking the device's administrative control.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it fundamentally compromises the security posture of the entire network infrastructure that relies on these devices for surveillance and monitoring. An attacker who successfully exploits this vulnerability can gain complete administrative control over the camera, potentially enabling them to modify video feeds, disable security features, redirect streams to unauthorized parties, or even use the device as a pivot point for further attacks within the network. The vulnerability is particularly dangerous because it requires no prior authentication and can be exploited simply by tricking a legitimate user into visiting a malicious website while maintaining their authenticated session with the device.
This vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery, and represents a classic example of how web applications must implement proper origin validation and token-based authentication mechanisms to prevent unauthorized operations. From an ATT&CK framework perspective, this vulnerability maps to techniques involving credential access and privilege escalation, as attackers can leverage the compromised administrative credentials to gain deeper access to network resources. The attack vector specifically relates to T1566.001 - Phishing: Spearphishing Attachment and T1078 - Valid Accounts, as the exploitation relies on social engineering to trick users into visiting malicious content while exploiting legitimate authentication sessions.
Mitigation strategies for CVE-2017-8407 require both immediate and long-term approaches to address the root cause. Immediate actions include implementing network segmentation to isolate these devices from critical infrastructure, disabling unnecessary web management interfaces, and ensuring that administrative credentials are changed to strong, unique passwords. Organizations should also deploy network monitoring solutions to detect unusual traffic patterns that might indicate exploitation attempts, particularly around the device's web management ports. Long-term solutions involve updating firmware to versions that include proper CSRF protection mechanisms, implementing multi-factor authentication for administrative access, and conducting regular security assessments of networked devices to identify similar vulnerabilities. Additionally, network administrators should establish policies that require regular credential rotation and implement strict access controls that limit administrative privileges to only necessary personnel. The vulnerability underscores the importance of implementing defense-in-depth strategies and the critical need for continuous security monitoring and device patch management across all networked assets.
