The SQL Injection vulnerability in the Yonyou U8 software allows an attacker to interfere with the queries that the application makes to its database. This vulnerability can be exploited by manipulating input data to execute arbitrary SQL statements. SQL Injection can provide unauthorized access to sensitive data, such as user details, or even allow an attacker to alter database records. With high severity, it poses significant risks by potentially granting an attacker administrative rights to the database. This vulnerability requires addressing as it compromises data integrity and poses threats to the application's security posture. Organizations using Yonyou U8 need to be aware of SQL injection to protect their data assets.

In this specific instance, the vulnerability exists in the bx_historyDataCheck endpoint of Yonyou U8. The application does not properly sanitize input provided by users via HTTP requests to this endpoint. As a result, attackers can inject malicious SQL code into the userName parameter of a form or request. The attack can be performed via a time-based approach, using the WAITFOR DELAY command to induce a time delay, confirming the vulnerability presence. The vulnerable endpoint is utilized during data check operations, which if manipulated can disrupt or expose sensitive user information. Consequently, failure to appropriately validate user inputs results in a severe security loophole susceptible to exploitation.

Exploitation of this SQL Injection vulnerability can lead to severe consequences for organizations using Yonyou U8. Attackers might gain unauthorized access to the application's database, allowing them to view, modify, or delete sensitive data without consent. This can lead to data breaches where sensitive business information is leaked, potentially damaging the company's reputation and customer trust. Furthermore, attackers could escalate privileges and gain full control of the database server, causing operational disruptions. In extreme cases, it can render the application unusable by corrupting essential data or application functionalities. Organizations need to act diligently to mitigate these potential threats and maintain data security.
