CVE-2024-40072 is a critical SQL injection vulnerability identified in the Sourcecodester Online ID Generator System 1.0. The vulnerability exists in the 'id' parameter within the URL path 'id_generator/admin/?page=generate/index&id=1'. This parameter is improperly sanitized, allowing an attacker to inject malicious SQL code directly into the backend database query. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), which typically enables attackers to manipulate database queries to extract, modify, or delete data without authorization. The CVSS v3.1 base score is 9.8, indicating a critical severity level. The vector string (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reveals that the attack can be executed remotely over the network without any privileges or user interaction, and it impacts confidentiality, integrity, and availability at a high level. Exploitation could lead to full compromise of the underlying database, including unauthorized data disclosure, data manipulation, or complete denial of service by corrupting or deleting data. Although no known exploits are currently reported in the wild, the ease of exploitation and critical impact make this vulnerability a high-risk threat. The lack of vendor or product-specific information limits precise targeting but suggests this vulnerability affects the Sourcecodester Online ID Generator System 1.0, which may be used in various web applications for ID generation purposes.

For European organizations, this vulnerability poses a significant risk, especially for entities relying on the Sourcecodester Online ID Generator System or similar web applications incorporating this component. Successful exploitation could lead to unauthorized access to sensitive data, including personal identifiable information (PII), financial records, or internal identifiers, violating GDPR and other data protection regulations. The integrity of critical business data could be compromised, leading to fraudulent activities or operational disruptions. Availability impacts could cause denial of service, affecting business continuity. Sectors such as finance, healthcare, government, and e-commerce, which often use ID generation systems for user or transaction management, are particularly vulnerable. The criticality of the vulnerability combined with the lack of authentication requirements means attackers can remotely exploit the system without credentials, increasing the attack surface. Additionally, the potential for data exfiltration or manipulation could damage organizational reputation and result in regulatory penalties within the European Union and other jurisdictions.

1. Immediate code review and patching: Organizations should audit the affected parameter 'id' in the 'id_generator/admin/?page=generate/index' endpoint to ensure proper input validation and parameterized queries or prepared statements are implemented to prevent SQL injection. 2. Web Application Firewall (WAF) deployment: Configure WAF rules to detect and block SQL injection patterns targeting the vulnerable parameter. 3. Network segmentation and access controls: Restrict access to the admin interface to trusted IP addresses or VPNs to reduce exposure. 4. Monitoring and logging: Implement detailed logging of database queries and web requests to detect anomalous activities indicative of exploitation attempts. 5. Conduct penetration testing focusing on injection flaws to identify similar vulnerabilities in related systems. 6. If patching is not immediately possible, consider disabling or restricting access to the vulnerable functionality temporarily. 7. Educate developers on secure coding practices, emphasizing the use of parameterized queries and input sanitization. 8. Regularly update and maintain all third-party components and dependencies to minimize exposure to known vulnerabilities.
