Mingyu Operation Insecure Authorization Scanner

The Mingyu operation and maintenance audit and risk control system is a software solution designed to provide security and risk management for IT infrastructures. It is used by organizations to safeguard their operations and ensure compliance with various security standards. The software monitors and analyzes network traffic and system logs to identify potential security issues. Typically used by security professionals and IT departments, Mingyu helps in identifying and mitigating risks before they can cause harm. It is particularly beneficial for enterprises with large IT ecosystems, offering robust features for comprehensive security management.

The vulnerability in Mingyu involves an SSRF (Server-Side Request Forgery) in the xmlrpc.sock interface. This vulnerability allows attackers to manipulate requests from within the system, potentially leading to unauthorized actions. SSRF attacks can be used to access restricted network resources, execute arbitrary requests, and gain unauthorized access to sensitive information. This kind of vulnerability can result in breach of internal systems, data theft, or unauthorized data alterations. Preventing such vulnerabilities is crucial as they pose significant threats to data integrity and confidentiality. The potential for misuse makes it a critical security concern for affected products.

Technically, the SSRF vulnerability is located in the xmlrpc.sock interface of the Anheng Mingyu system. By exploiting the interface, an attacker can send crafted requests that manipulate server-side actions. The vulnerability specifically allows adding any user account, which could be misused to gain unauthorized administrative access. The endpoint POST /service/?unix:/../../../../var/run/rpc/xmlrpc.sock|http:// allows for such injection, making it a critical risk factor. Furthermore, parameters such as 'uname' and 'pwd' in the XML payload are vulnerable. Addressing these technical loopholes requires meticulous attention to request handling and input validation.

Exploiting this SSRF vulnerability can have severe implications including unauthorized user creation and potential access to sensitive resources. If malicious actors gain control, they could perform arbitrary operations, compromise data integrity, or pivot to other vulnerable systems. This could lead to data breaches, loss of sensitive information, and operational disruption. Therefore, businesses using affected systems must prioritize fixing this vulnerability to minimize risk exposure. Failure to do so could result in substantial financial and reputational damage. Proactive measures are essential to protect the underlying infrastructure.
