CVE-2024-54762 is an authenticated SQL injection vulnerability found in Ruoyi, an open-source Java-based rapid development framework widely used for enterprise applications. The vulnerability exists in versions 4.7.9 and earlier due to an incomplete filtering mechanism in the filterKeyword method, which is intended to sanitize input by removing or neutralizing SQL injection keywords. However, this method does not fully prevent malicious SQL code from being injected, allowing an authenticated user to manipulate SQL queries executed by the application. This can lead to unauthorized data access, modification, or deletion, impacting the confidentiality, integrity, and availability of the backend database. The vulnerability requires the attacker to have valid credentials and perform some user interaction, which limits exploitation to insiders or compromised accounts. The CVSS 3.1 base score of 6.3 reflects a medium severity level, with attack vector being network-based, low attack complexity, no privileges required beyond authentication, and user interaction necessary. Currently, there are no known exploits in the wild, and no official patches have been released, increasing the urgency for organizations to implement interim mitigations. The vulnerability is categorized under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), a common and critical class of injection flaws. Given Ruoyi's popularity in Chinese enterprise environments and growing adoption in other regions, this vulnerability poses a tangible risk to organizations relying on this framework for their business-critical applications.

The potential impact of CVE-2024-54762 includes unauthorized access to sensitive data, data manipulation, and disruption of service availability. Since the vulnerability allows SQL injection, attackers can potentially extract confidential information, alter database records, or cause denial of service by corrupting data or triggering errors. Although exploitation requires authentication and user interaction, the risk remains significant for organizations with many users or where insider threats are possible. The compromise of database integrity can lead to financial loss, reputational damage, regulatory penalties, and operational disruption. Enterprises using Ruoyi in sectors such as finance, healthcare, government, and e-commerce are particularly vulnerable due to the sensitive nature of their data. The absence of known exploits currently provides a window for proactive defense, but the medium severity score indicates that the vulnerability should be addressed promptly to prevent escalation or chaining with other vulnerabilities.

To mitigate CVE-2024-54762, organizations should first restrict access to the Ruoyi application to trusted users and enforce strong authentication mechanisms to reduce the risk of compromised credentials. Developers should review and enhance the filterKeyword method or replace it with a more robust input validation and sanitization approach, such as using parameterized queries (prepared statements) to prevent SQL injection entirely. Until an official patch is available, implementing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns can provide an additional layer of defense. Regularly auditing user activities and monitoring logs for unusual database queries or errors can help detect attempted exploitation. Organizations should also educate users about the risks of phishing and credential compromise to minimize the likelihood of attackers gaining authenticated access. Finally, maintaining an up-to-date inventory of affected systems and preparing for rapid patch deployment once available is critical for long-term security.
