EUVD-2024-48067

Comprehensive Technical Analysis of EUVD-2024-48067

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2024-48067, also known as CVE-2024-7071, pertains to an SQL Injection flaw in Brain Low-Code, a product developed by Brain Information Technologies Inc. The vulnerability arises from improper neutralization of special elements used in an SQL command, specifically within the Hibernate framework. This issue affects versions of Brain Low-Code prior to 2.1.0.

Severity Evaluation:

• Base Score: 9.3 (Critical)
• Base Score Version: 4.0
• Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

The high base score indicates a critical vulnerability due to the following factors:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Confidentiality (VC): High (H)
• Integrity (VI): High (H)
• Availability (VA): High (H)

This vulnerability can be exploited remotely without requiring any special privileges or user interaction, making it highly dangerous.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker can exploit this vulnerability over the network.
• Web Applications: Any web application using Brain Low-Code versions prior to 2.1.0 is susceptible.

Exploitation Methods:

• SQL Injection: An attacker can inject malicious SQL code into input fields that are not properly sanitized. This can lead to unauthorized access to the database, data manipulation, and extraction.
• Automated Tools: Attackers may use automated tools to scan for and exploit SQL injection vulnerabilities.

3. Affected Systems and Software Versions

Affected Software:

• Brain Low-Code: Versions prior to 2.1.0

Affected Systems:

• Any system running the vulnerable versions of Brain Low-Code, particularly those with network exposure.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade: Upgrade to Brain Low-Code version 2.1.0 or later, which includes the necessary patches to mitigate this vulnerability.
• Input Validation: Implement robust input validation and sanitization mechanisms to prevent SQL injection.
• Parameterized Queries: Use parameterized queries or prepared statements to ensure that SQL code is not directly manipulated by user input.
• Web Application Firewalls (WAF): Deploy WAFs to detect and block SQL injection attempts.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.
• Security Training: Provide training for developers on secure coding practices, particularly focusing on SQL injection prevention.
• Patch Management: Establish a robust patch management process to ensure timely updates and patches are applied.

5. Impact on European Cybersecurity Landscape

The presence of such a critical vulnerability in a widely used low-code platform like Brain Low-Code poses significant risks to organizations across Europe. The potential for data breaches, unauthorized access, and data manipulation can lead to severe financial and reputational damage. This underscores the need for vigilant cybersecurity practices and timely response to vulnerabilities.

6. Technical Details for Security Professionals

Vulnerability Details:

• CWE ID: CWE-564 (SQL Injection)
• Vulnerable Component: Hibernate framework within Brain Low-Code
• Exploitability: High, due to the low complexity and lack of required privileges or user interaction.

Detection and Response:

• Detection: Use intrusion detection systems (IDS) and intrusion prevention systems (IPS) to monitor for suspicious SQL queries.
• Response: Implement incident response plans to quickly identify and mitigate any successful exploitation attempts.
