D-Link DIR-610 devices allow Remote Command Execution via the cmd parameter to command.php. This vulnerability only affects products that are no longer supported by the maintainer. The CVSS score for this vulnerability is 8.8, classifying it as high severity. Organizations using these devices face significant risks due to the potential for unauthorized access and control. As the affected products are no longer supported, organizations must take immediate action.
Risk to organizations includes exposure to unauthorized command execution, which can result in data breaches and system manipulations. Given the vulnerability's high CVSS score, organizations should prioritize patching immediately. The potential for exploitation is critical, especially since the vulnerability has been listed in the Known Exploited Vulnerabilities (KEV) catalog.
Furthermore, the urgency for remediation is heightened as the lack of vendor support leaves systems exposed. Organizations are advised to disconnect any affected devices that remain in use. This proactive measure can mitigate the risks associated with the vulnerability.
In conclusion, the D-Link DIR-610 vulnerability presents a serious security risk that requires immediate attention. Organizations must assess their exposure and take appropriate action to safeguard their systems.
Vulnerability Details
The D-Link DIR-610 devices are affected by a vulnerability that allows remote command execution through the cmd parameter in command.php. This vulnerability has been classified under CWE-78, indicating a command injection issue. The CVSS version 3.1 score is 8.8, categorizing the severity as high. The CVSS vector indicates a network attack vector with low complexity and low privileges required, thus making it easier for attackers to exploit the vulnerability. The vulnerability was published on July 9, 2020, and has been analyzed thoroughly.
Technical Analysis
The root cause of this vulnerability lies in improper input validation of the cmd parameter within the command.php file. Attackers can exploit this flaw by sending crafted requests to the affected devices over the network. The attack complexity is rated as low, meaning that it requires minimal effort to execute. Additionally, the attack does not necessitate user interaction, which increases the risk of exploitation.
Regarding the impact, the vulnerability affects confidentiality, integrity, and availability, all rated as high. This means that successful exploitation could result in unauthorized access to sensitive data, modification or deletion of data, and disruption of services. Organizations using these devices are at significant risk due to the potential consequences of exploitation.
Risk & Impact Analysis
Real-world deployment risk for this vulnerability is critical, especially for organizations still utilizing the D-Link DIR-610 devices. The blast radius encompasses any system connected to these devices, potentially affecting a wide range of organizational operations. The urgency assessment based on the CVSS score indicates that organizations should prioritize patching immediately due to the very high potential for exploitation.
Given the device's end-of-life status, organizations must recognize the importance of disconnecting these devices to prevent unauthorized access and potential data breaches. The lack of vendor support significantly increases the urgency for remediation.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | Yes |
Ransomware Use | No |
Affected Versions
The affected versions include all D-Link DIR-610 firmware versions prior to the vendor patch. As the product is end-of-life, there are no further updates or patches available.
Mitigation & Remediation
Organizations should prioritize remediation by disconnecting any D-Link DIR-610 devices that are still in use. This step is critical to mitigate the risks associated with the vulnerability. As there are no patches available due to the end-of-life status of the product, organizations must assess their network environment and consider replacing these devices with supported alternatives. For best practices, organizations can engage in penetration testing to identify additional vulnerabilities and ensure their network security.
Detection Guidance
Organizations should monitor logs for any anomalous activity originating from D-Link DIR-610 devices. Indicators of compromise may include unusual command execution attempts or unauthorized access attempts. Additionally, behavioral anomalies within the network should be investigated promptly.
AppSecure Threat Intelligence Insight
The D-Link DIR-610 remote command execution vulnerability highlights the importance of maintaining up-to-date and supported devices within organizational environments. Security teams should note the trend of vulnerabilities associated with end-of-life products as attackers often exploit these weaknesses. For organizations still using unsupported devices, it is crucial to have a comprehensive vulnerability management program in place to address potential risks. Furthermore, adopting continuous security practices, such as penetration testing methodology, can help identify and remediate vulnerabilities before they are exploited.
Ultimately, the D-Link DIR-610 vulnerability serves as a reminder of the critical nature of device management and timely remediation to enhance overall security posture.
