CVE-2024-25847

Comprehensive Technical Analysis of CVE-2024-25847

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-25847 CISA Vulnerability Name: CVE-2024-25847 CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This score is derived from the potential for privilege escalation and unauthorized access to sensitive information, which can have severe implications for data integrity, confidentiality, and availability.

2. Potential Attack Vectors and Exploitation Methods

The vulnerability is an SQL Injection flaw in the "Product Catalog (CSV, Excel) Import" module for PrestaShop. Specifically, the Send::__construct() and importProducts::_addDataToDb methods are susceptible to SQL Injection attacks.

Attack Vectors:

• Unsanitized Input: An attacker can inject malicious SQL code through the import functionality, which is not properly sanitized.
• Privilege Escalation: By exploiting the SQL Injection, an attacker can escalate their privileges within the database, potentially gaining administrative access.
• Data Exfiltration: The attacker can extract sensitive information from the database, including user credentials, financial data, and other confidential information.

Exploitation Methods:

• Crafted Input: The attacker can craft a specially designed CSV or Excel file containing malicious SQL queries.
• Automated Tools: Use of automated SQL Injection tools to identify and exploit the vulnerability.
• Manual Exploitation: Manual injection of SQL commands through the import functionality to gain unauthorized access.

3. Affected Systems and Software Versions

Affected Software:

• MyPrestaModules "Product Catalog (CSV, Excel) Import" (simpleimportproduct) modules for PrestaShop

Affected Versions:

• PrestaShop versions 6.5.0 and before

Impacted Components:

• Send::__construct() method
• importProducts::_addDataToDb method

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest security patches provided by the vendor to mitigate the vulnerability.
• Input Validation: Implement strict input validation and sanitization for all user inputs, especially in the import functionality.
• Database Security: Use prepared statements and parameterized queries to prevent SQL Injection.
• Access Controls: Restrict access to the import functionality to trusted users only.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and code reviews to identify and fix vulnerabilities.
• Security Training: Provide security training for developers to understand and mitigate common vulnerabilities like SQL Injection.
• Monitoring: Implement continuous monitoring and logging to detect and respond to suspicious activities.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2024-25847 highlights the ongoing risk of SQL Injection vulnerabilities in web applications.

The potential for privilege escalation and data exfiltration can have significant impacts on businesses, including financial loss, reputational damage, and legal consequences.

6. Technical Details for Security Professionals

Vulnerability Details:

• The Send::__construct() method and importProducts::_addDataToDb method do not properly sanitize user inputs, allowing for SQL Injection attacks.
• The vulnerability can be exploited by injecting malicious SQL code through the import functionality, leading to unauthorized access and data exfiltration.

Detection Methods:

• Static Analysis: Use static code analysis tools to identify unsanitized inputs and potential SQL Injection points.
• Dynamic Analysis: Conduct dynamic analysis and penetration testing to detect and exploit the vulnerability.
• Log Analysis: Review database logs for unusual queries and activities that may indicate an SQL Injection attempt.

Mitigation Steps:

• Code Review: Conduct a thorough code review of the affected methods to ensure proper input validation and sanitization.
• Database Configuration: Ensure the database is configured to use the least privilege principle, limiting the impact of a successful SQL Injection attack.
• Web Application Firewall (WAF): Deploy a WAF to detect and block SQL Injection attempts in real-time.

Conclusion: CVE-2024-25847 is a critical SQL Injection vulnerability affecting PrestaShop's "Product Catalog (CSV, Excel) Import" module. Immediate patching and implementation of robust input validation are essential to mitigate the risk. Continuous monitoring and regular security assessments are crucial to prevent similar vulnerabilities in the future.
