CVE-2025-66744 Scanner

Yonyou YonBIP is a comprehensive Enterprise Resource Planning (ERP) software used globally by businesses for managing a wide range of business processes, including finance, human resources, and customer relations. It offers a unified platform that integrates various business functions and operations, streamlining workflows and increasing operational efficiency. Due to its wide array of features and capabilities, YonBIP is employed by medium to large enterprises seeking to optimize their management processes across departments. This software is crucial in providing insights and data-driven decision-making for businesses, making it an essential tool for enterprises looking to leverage technology to maintain competitiveness. Many organizations rely on YonBIP's modular design and flexible deployment options, which allow for tailored solutions that meet specific organizational needs. Despite its advantages, vulnerabilities such as path traversal can put sensitive business information at risk, making regular security checks and updates imperative for users of this platform.

The Path Traversal vulnerability identified in Yonyou YonBIP arises from inadequate validation in the LoginWithV8 API interface. This security flaw allows unauthorized users to manipulate file paths and access directories beyond the intended directory scope of the web server. Such vulnerabilities are critical as they can expose sensitive data that is not intended to be accessed by end-users, potentially leading to data breaches. Attackers can exploit these flaws to read files such as configuration files, credentials, and other sensitive server files, which can escalate to further attacks. Path Traversal remains a common vulnerability due to improper input validation, underscoring the need for secure coding practices. This vulnerability emphasizes the importance of maintaining strict access controls and validating user inputs effectively to preserve data integrity. Organizations running affected versions of YonBIP must address this issue urgently to prevent unauthorized data access.

The vulnerability in Yonyou YonBIP is specific to its LoginWithV8 interface, where improper directory validation permits unauthorized path traversal. By crafting specific URL requests, attackers can navigate through the directory structure of the server. For example, sending a request with path manipulations like ../../../' can potentially enable directory traversal, leading to unauthorized file access. The targeted endpoint utilizes parameters that are not adequately sanitized, thereby allowing malicious actors to exploit these entries. As a result, sensitive data, such as system configuration files, could be exposed, providing attackers with the critical information needed to perform further attacks. Given the severity of the issue, a detailed understanding of the affected component's functionality and continuous monitoring is necessary to protect against exploitation. Maintaining updated security patches and implementing robust input validation significantly contributes to mitigating this risk.

If exploited, this path traversal vulnerability can expose sensitive data, such as employee records, financial information, and proprietary company information, to unauthorized individuals. Such data exposure could lead to various forms of exploitation, including identity theft, financial fraud, and the leakage of confidential business strategies. Unauthorized access could cause significant reputational damage to the affected organization, leading to loss of customer trust and potential legal challenges. Beyond data theft, attackers gaining access to sensitive information might manipulate or delete critical files, impacting business operations and causing downtime. Furthermore, compromised data can be used as a foothold for launching more sophisticated attacks on the affected network, further escalating the risk. It is crucial for enterprises relying on YonBIP to implement the recommended security measures to mitigate the risks associated with this vulnerability.
