CVE-2022-40485 is a critical SQL injection vulnerability identified in the Wedding Planner v1.0 web application. The vulnerability exists in the 'id' parameter of the /package_detail.php page, which is susceptible to injection of malicious SQL code. This flaw allows an unauthenticated attacker to execute arbitrary SQL commands on the backend database by manipulating the 'id' parameter in HTTP requests. The vulnerability is characterized by CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), indicating that user input is not properly sanitized or parameterized before being incorporated into SQL queries. The CVSS v3.1 base score of 9.8 reflects the high severity, with an attack vector of network (AV:N), no required privileges (PR:N), no user interaction (UI:N), and full impact on confidentiality, integrity, and availability (C:H/I:H/A:H). This means an attacker can remotely exploit this vulnerability without authentication or user interaction, potentially leading to complete compromise of the database, including data disclosure, data modification, or deletion, and possibly further system compromise if the database is linked to other application components. No patches or vendor information are currently available, and no known exploits in the wild have been reported yet. However, given the critical nature and ease of exploitation, this vulnerability poses a significant risk to any deployment of Wedding Planner v1.0 that remains unpatched or unmitigated.

For European organizations using Wedding Planner v1.0, this vulnerability could lead to severe consequences including unauthorized access to sensitive customer data, manipulation or deletion of booking and package information, and disruption of business operations. The exposure of personal data could result in violations of the EU General Data Protection Regulation (GDPR), leading to substantial fines and reputational damage. Additionally, attackers could leverage the compromised database as a foothold to pivot into internal networks, potentially affecting other systems and services. The critical severity and remote exploitability without authentication make this vulnerability particularly dangerous for organizations with public-facing web applications. Small and medium enterprises in the hospitality and event planning sectors, which may rely on such software, are at heightened risk due to potentially limited cybersecurity resources and awareness.

Given the absence of official patches, European organizations should immediately implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the 'id' parameter on /package_detail.php. 2) Conduct thorough input validation and sanitization on all user-supplied data, especially the 'id' parameter, using parameterized queries or prepared statements to prevent injection. 3) Restrict database user privileges to the minimum necessary, avoiding use of high-privilege accounts for web application database connections. 4) Monitor web server and database logs for suspicious activity indicative of SQL injection attempts. 5) If possible, isolate the affected application environment from critical internal networks to limit lateral movement. 6) Plan and prioritize upgrading or replacing the vulnerable Wedding Planner v1.0 application with a secure version or alternative solution. 7) Educate development and IT teams about secure coding practices and the risks of SQL injection vulnerabilities.
