EUVD-2024-53633

Comprehensive Technical Analysis of EUVD-2024-53633

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2024-53633, also known as CVE-2024-57587, pertains to multiple SQL injection vulnerabilities in EasyVirt DCScope versions 8.6.0 and earlier, as well as CO2Scope versions 1.3.0 and earlier. The vulnerability allows remote unauthenticated attackers to execute arbitrary SQL commands via the username or password parameters in the /api/auth/login endpoint.

Severity Evaluation:

• Base Score: 9.1
• Base Score Version: CVSS:3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

The CVSS score of 9.1 indicates a critical vulnerability. The vector string breakdown is as follows:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): None (N)

This high score reflects the severe impact on confidentiality and integrity, with no requirement for user interaction or special privileges, making it highly exploitable.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Unauthenticated Attack: The vulnerability can be exploited remotely without any authentication, making it a high-risk target for attackers.
• SQL Injection: Attackers can inject malicious SQL commands through the username or password parameters in the login API.

Exploitation Methods:

• SQL Command Execution: Attackers can craft SQL queries to extract sensitive data, modify database entries, or execute administrative operations.
• Data Exfiltration: By injecting SQL commands, attackers can exfiltrate confidential information such as user credentials, personal data, and other sensitive information.
• Database Manipulation: Attackers can alter database contents, delete records, or insert malicious data, leading to data integrity issues.

3. Affected Systems and Software Versions

Affected Software:

• EasyVirt DCScope: Versions 8.6.0 and earlier
• EasyVirt CO2Scope: Versions 1.3.0 and earlier

Affected Systems:

• Any system running the affected versions of EasyVirt DCScope or CO2Scope, particularly those with the /api/auth/login endpoint exposed to the internet.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Upgrade to the latest versions of EasyVirt DCScope and CO2Scope that address this vulnerability.
• Input Validation: Implement strict input validation and sanitization for all user inputs, especially for the username and password parameters.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection attacks.
• Web Application Firewall (WAF): Deploy a WAF to detect and block SQL injection attempts.

Long-Term Mitigation:

• Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.
• Security Training: Provide security training for developers to ensure they are aware of common vulnerabilities and best practices for secure coding.
• Monitoring and Logging: Implement robust monitoring and logging mechanisms to detect and respond to suspicious activities promptly.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using EasyVirt DCScope and CO2Scope, particularly those in critical sectors such as healthcare, finance, and government. The potential for data breaches and unauthorized access can lead to severe financial and reputational damage. Given the critical nature of the vulnerability, it underscores the importance of timely patching and proactive security measures in the European cybersecurity landscape.

6. Technical Details for Security Professionals

Technical Analysis:

• Vulnerable Endpoint: /api/auth/login
• Parameters: username, password
• Exploit Method: Injecting SQL commands into the username or password fields.

Example Exploit:

username: ' OR '1'='1
password: ' OR '1'='1

Mitigation Code Example:

import sqlite3

def secure_login(username, password):
    conn = sqlite3.connect('database.db')
    cursor = conn.cursor()
    query = "SELECT * FROM users WHERE username = ? AND password = ?"
    cursor.execute(query, (username, password))
    result = cursor.fetchone()
    conn.close()
    return result
