This vulnerability allows multiple cross-site request forgery (CSRF) vulnerabilities in the D-Link DIR-600 router (rev. Bx) with firmware before 2.17b02. Attackers may leverage this flaw to hijack the authentication of administrators for various critical requests. The vulnerabilities permit actions such as creating an administrator account, enabling remote management, activating new configuration settings, or sending a ping to diagnostic interfaces.
With a CVSS score of 8.0, classified as high severity, this vulnerability poses significant risks to organizations that utilize these devices. The attack vector is adjacent network, indicating that an attacker within proximity can exploit this vulnerability. The attack complexity is low, and the required privileges are also low, making it easier for potential attackers to execute successful exploits.
Risk to organizations includes unauthorized access to critical device configurations, which can lead to further network vulnerabilities. Organizations should prioritize patching immediately to mitigate these risks, especially since this vulnerability affects legacy D-Link products that have reached their end-of-life (EOL) or end-of-service (EOS) life cycle.
The urgency for defenders is heightened by the fact that this vulnerability is included in the CISA Known Exploited Vulnerabilities (KEV) catalog, indicating that it is actively being targeted in the wild.
Vulnerability Details
The D-Link DIR-600 router (rev. Bx) suffers from multiple CSRF vulnerabilities due to improper validation of requests. This vulnerability is classified under CWE-352. The CVSS score of 8.0 indicates a high severity level, reflecting the potential impact on confidentiality, integrity, and availability. The affected product is the DIR-600 firmware, with a publication date of January 13, 2015.
Technical Analysis
The root cause of this vulnerability lies in the lack of anti-CSRF tokens in the affected configuration endpoints. This allows unauthorized users to craft malicious requests that can be executed with the privileges of an authenticated administrator. The attack vector is local to the adjacent network, meaning an attacker must be within network range. The attack complexity is low as no special conditions are required to exploit this vulnerability, and the attacker requires only low privileges.
User interaction is not required, allowing the attacker to execute malicious requests without any intervention from the administrator. The potential impacts of this vulnerability include high confidentiality, integrity, and availability risks, as attackers may change router configurations or disrupt services.
Risk & Impact Analysis
Organizations utilizing D-Link DIR-600 routers should be aware of the significant risks posed by this vulnerability. The ability for attackers to hijack administrator sessions can lead to unauthorized configuration changes, potentially exposing sensitive network data or disrupting services. The inclusion of this vulnerability in the CISA KEV catalog signifies that the threat is not only theoretical but actively being exploited in the wild.
Organizations should assess their deployment of affected D-Link products and prioritize remediation efforts accordingly. Timely patching is critical, especially considering the high CVSS score and the low attack complexity, which underscores the urgency of addressing this vulnerability.

Affected Versions
The D-Link DIR-600 router firmware versions prior to 2.17b02 are affected by this vulnerability. Organizations should ensure their devices are updated to the latest firmware to mitigate these risks.
Mitigation & Remediation
To remediate this vulnerability, organizations should immediately patch their D-Link DIR-600 routers to the latest firmware version. For those unable to apply patches, consider implementing network controls to limit access to management interfaces. Regular monitoring for unauthorized changes is also recommended. Organizations should validate remediation through penetration testing to identify similar weaknesses.
Detection Guidance
Organizations should monitor logs for unusual access patterns and behavioral anomalies that could indicate exploitation attempts. Specific indicators include unauthorized configuration changes and unexpected access to administrative interfaces.
AppSecure Threat Intelligence Insight
This vulnerability highlights the importance of maintaining up-to-date firmware on network devices to prevent CSRF attacks. Security teams should implement best practices for securing administrative interfaces and consider regular security assessments. For comprehensive security assessments, organizations should explore application security assessments to ensure all potential vulnerabilities are identified and addressed. Additionally, leveraging red teaming services can provide insights into potential attack vectors that may exploit similar vulnerabilities in the future.
Finally, organizations should stay informed about the evolving threat landscape by referring to resources such as the penetration testing methodology for proactive measures against potential vulnerabilities.
