Comprehensive Technical Analysis of EUVD-2025-204840

1. Vulnerability Assessment and Severity Evaluation

The EUVD entry EUVD-2025-204840 describes a critical SQL Injection vulnerability in RuoYi versions 4.7.9 and earlier. The vulnerability allows a remote attacker to execute arbitrary code via the createTable function in SqlUtil.java. The CVSS (Common Vulnerability Scoring System) base score of 10.0 indicates the highest level of severity. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
• Privileges Required (PR): None (N) - No special privileges are needed to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Changed (C) - The vulnerability affects a different security scope.
• Confidentiality (C): High (H) - Complete loss of confidentiality.
• Integrity (I): High (H) - Complete loss of integrity.
• Availability (A): High (H) - Complete loss of availability.

This high severity score underscores the critical nature of the vulnerability, making it a top priority for immediate remediation.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector for this vulnerability is through the createTable function in SqlUtil.java. An attacker can exploit this vulnerability by crafting malicious SQL statements that are executed by the application. Potential exploitation methods include:

• Direct SQL Injection: An attacker can inject SQL commands directly into the input fields that are processed by the createTable function.
• Blind SQL Injection: An attacker can use blind SQL injection techniques to extract information from the database without direct feedback from the application.
• Automated Tools: Attackers may use automated tools to scan for and exploit SQL injection vulnerabilities.

3. Affected Systems and Software Versions

The vulnerability affects RuoYi versions 4.7.9 and earlier. RuoYi is a popular open-source project management system, and any organization using these versions is at risk. It is crucial to identify and update all instances of RuoYi to a patched version to mitigate the risk.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Immediate Patching: Upgrade to the latest version of RuoYi that includes the security patch for this vulnerability.
• Input Validation: Implement robust input validation and sanitization to prevent malicious SQL commands from being executed.
• Parameterized Queries: Use parameterized queries or prepared statements to ensure that SQL commands are executed safely.
• Web Application Firewalls (WAF): Deploy WAFs to detect and block SQL injection attempts.
• Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify and address potential security issues.
