The vulnerability has a CVSS (Common Vulnerability Scoring System) base score of 9.8, which is categorized as critical. The CVSS vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates the following:

• Attack Vector (AV:N): The vulnerability can be exploited remotely over the network.
• Attack Complexity (AC:L): The attack requires low complexity to exploit.
• Privileges Required (PR:N): No privileges are required to exploit the vulnerability.
• User Interaction (UI:N): No user interaction is required for the attack to succeed.
• Scope (S:U): The vulnerability affects the same security scope.
• Confidentiality (C:H): The vulnerability has a high impact on confidentiality.
• Integrity (I:H): The vulnerability has a high impact on integrity.
• Availability (A:H): The vulnerability has a high impact on availability.

Given the high scores in all impact metrics, this vulnerability poses a significant risk to systems running the affected module.

2. Potential Attack Vectors and Exploitation Methods

SQL injection vulnerabilities are typically exploited by injecting malicious SQL code into input fields that are not properly sanitized. In this case, an attacker could:

• Inject SQL Commands: By crafting specific input to the vulnerable module, an attacker could execute arbitrary SQL commands.
• Extract Sensitive Data: The attacker could extract sensitive information from the database, such as user credentials, payment information, and other confidential data.
• Modify Database Content: The attacker could alter database entries, leading to data integrity issues.
• Delete Data: The attacker could delete critical data, causing loss of availability.

Common exploitation methods include:

• Automated Tools: Using automated SQL injection tools to identify and exploit the vulnerability.
• Manual Exploitation: Crafting custom SQL queries to exploit the vulnerability manually.

3. Affected Systems and Software Versions

The vulnerability affects PrestaShop versions prior to 2.4.3 that use the "Length, weight or volume sell" module (ailinear). Organizations running these versions are at risk and should prioritize updating to a patched version.

4. Recommended Mitigation Strategies

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

• Update Software: Immediately update to PrestaShop version 2.4.3 or later, which includes the patch for this vulnerability.
• Input Validation: Implement robust input validation and sanitization mechanisms to prevent SQL injection attacks.
• 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 Audits: Conduct regular security audits and vulnerability assessments to identify and address similar issues.
• Monitoring and Logging: Implement comprehensive monitoring and logging to detect any suspicious activities related to SQL injection.

5. Impact on European Cybersecurity Landscape
