Dahua Smart Park Integrated Management Platform Arbitrary File Upload Scanner

The Dahua Smart Park Integrated Management Platform is used by businesses and municipalities to manage and monitor various aspects of large-scale facilities, including parking, surveillance, and security systems. It streamlines administrative tasks by integrating multiple functionalities into a single platform, providing users with operational efficiencies. Facility managers and security personnel commonly utilize this platform to ensure effective management of resources and people flow. The platform is widely deployed in smart city projects and large venues, offering real-time data and analytics for decision-making. With its expansive reach, it provides scalable solutions to meet the dynamic needs of modern facilities. Dahua's platform is often integrated with IoT devices to enhance automated control and monitoring capabilities.

The Arbitrary File Upload vulnerability allows attackers to upload malicious files to a server through a flawed file upload mechanism. Exploiting such vulnerabilities can enable attackers to execute code remotely or gain unauthorized access to systems. This type of vulnerability is commonly found in web applications that insufficiently validate or sanitize file inputs, allowing potentially harmful files to be processed. Attackers may exploit this weakness to upload scripts or executables, posing risks of data theft, further system compromise, or launching attacks against other systems. Ensuring robust validation and limiting file types are essential steps in mitigating this risk. Affected systems require immediate patches or security controls to prevent unauthorized file uploads.

This vulnerability exploits the video upload interface on the Dahua Smart Park Integrated Management Platform. The interface lacks sufficient validation checks, allowing unauthorized files to be uploaded without restriction. By manipulating the HTTP form data, attackers can bypass existing security measures to upload JSP or other executable files. Successful exploitation relies on crafting specific requests to the server, targeting the designated upload endpoint. The vulnerability is accessible through a multipart request containing an arbitrary file, which is then stored on the server. Once uploaded, these files can execute server-side operations, leveraging system-level permissions to extend control over server resources.

Exploiting this vulnerability can lead to significant impacts, including unauthorized server access and potential full system compromise. Attackers might deploy malware, exfiltrate sensitive information, or pivot to attack connected systems and networks. The uploaded malicious files can initiate further attacks such as privilege escalation or denial of service. Additionally, it can result in reputational damage and financial loss for organizations relying on the platform. There are heightened risks of exposure of proprietary data and violation of regulatory compliance standards if personal data is accessed unlawfully. Organizations need to implement strict monitoring and anomaly detection to detect such unauthorized actions.
