Kingdee OA Yunxingkong Remote Code Execution Scanner

Kingdee OA Yunxingkong kdsvc is a component of the Kingdee Cloud Starry Sky Management Center, widely utilized in various enterprises for efficient management of business processes. It is primarily used by business professionals and IT departments to streamline operations and integrate different business functions. The software is versatile, offering solutions for finance, supply chain management, human resources, and more, making it a popular choice for organizations seeking comprehensive enterprise resource planning (ERP) solutions. Its architecture allows for scalable deployment, suitable for both small businesses and large corporations. The platform is designed to provide real-time insights and facilitate decision-making, contributing to organizational efficiency.

The Kingdee OA Yunxingkong kdsvc module has been identified to contain a Remote Code Execution (RCE) vulnerability. This type of vulnerability allows attackers to execute arbitrary code on the affected system, typically due to inadequate input validation or lack of proper authorization controls. In the case of Kingdee OA Yunxingkong kdsvc, the communication protocol used does not enforce proper verification, leading to potential exploitation. This can result in unauthorized access and manipulation of critical data, posing significant risks to enterprise security. Effective detection and remediation of this vulnerability are crucial in maintaining system integrity and protecting sensitive information.

The technical details surrounding this vulnerability involve flaws in the serialization and deserialization process within the Kingdee OA Yunxingkong kdsvc communication protocol. The affected endpoint, "Kingdee.BOS.ServiceFacade.ServicesStub.DevReportService.GetBusinessObjectData.common.kdsvc," is susceptible to exploitation due to the binary data format being used without signature verification. This lack of security in data transmission allows attackers to inject harmful commands, with the dispatcher 'cmd' being a primary vector. The vulnerability requires careful parsing and verification of data to be mitigated effectively. Unlike typical authentication measures, the protocol's design falls short in preventing such remote code execution attempts.

Exploitation of the RCE vulnerability in Kingdee OA Yunxingkong kdsvc can lead to severe consequences, including unauthorized control over the system. Malicious actors could execute arbitrary code, potentially leading to data breaches, theft of sensitive information, and disruption of business operations. Furthermore, attackers could install malware, deface web applications, or use the compromised systems as launch points for further attacks. The ripple effect of such breaches can damage organizational reputation, result in financial losses, and lead to legal liabilities. Immediate assessment and reinforcement of security measures are imperative to prevent exploitation.
