Dahua Smart Park Arbitrary File Upload Scanner

Dahua Smart Park is an integrated management platform often employed in smart city applications. It's used by municipalities and private establishments for surveillance and monitoring purposes. The platform integrates with numerous IoT devices to manage parks, facilities, and other infrastructures effectively. Users can access the system through web interfaces for monitoring and administrative tasks. Dahua Smart Park ensures that facilities are operated efficiently and safely by leveraging a centralized data repository. The platform facilitates the management of physical security and operational monitoring seamlessly.

An Arbitrary File Upload vulnerability allows attackers to upload unauthorized files to a server. In this context, it means that files can be uploaded without authentication, potentially leading to malicious exploitation. This vulnerability arises when the platform does not properly validate or restrict the types of files that can be uploaded. Attackers might upload executable scripts or malware, taking advantage of this oversight. Malicious uploads can bypass security protocols, possibly leading to detrimental consequences. Preventive measures should be implemented, considering the levels of risk associated with such vulnerabilities.

The vulnerable endpoint is identified within the Dahua Smart Park platform at /emap/webservice/gis/soap/poi. The SOAP-based frontend interface neglects proper authorization checks, facilitating this exploitable point. The lack of sufficient input validation permits unwanted files to be sent and stored on the server. Attack vectors include embedding harmful base64-encoded files, as facilitated by the template. Interactions typically happen over HTTP POST with a corresponding XML payload. Verification of a successful exploit can be conducted through subsequent GET requests targeting the known upload directory.

By exploiting this vulnerability, attackers may gain unauthorized access and control over the server. Uploaded files may execute malicious code remotely, potentially resulting in data breaches. Data integrity and security can be significantly compromised, leading to reputational damage and potential financial losses. Unauthorized file uploads can pivot to further attacks, such as privilege escalation. Organizations must prioritize patching this security gap to mitigate the risk of exploitation.
