CVE-2022-40483 is a critical SQL injection vulnerability identified in Wedding Planner v1.0, specifically exploitable via the 'id' parameter in the /wedding_details.php page. SQL injection (CWE-89) vulnerabilities occur when user-supplied input is improperly sanitized, allowing attackers to inject malicious SQL queries into the backend database. This vulnerability has a CVSS 3.1 base score of 9.8, indicating a critical severity level. The vector metrics (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reveal that the attack can be performed remotely over the network without any privileges or user interaction, and it impacts confidentiality, integrity, and availability at a high level. Exploiting this flaw could allow an attacker to retrieve, modify, or delete sensitive data stored in the database, potentially leading to data breaches, unauthorized data manipulation, or complete system compromise. Although no patches or vendor information are provided, the vulnerability is publicly disclosed and recognized by MITRE and CISA, emphasizing the need for immediate attention. No known exploits are currently reported in the wild, but the ease of exploitation and impact make it a significant threat if Wedding Planner v1.0 is in use.

For European organizations using Wedding Planner v1.0, this vulnerability poses a severe risk to the confidentiality and integrity of their data. Wedding planning software often contains personal and sensitive information about clients, including names, contact details, event dates, and possibly payment information. Exploitation could lead to unauthorized disclosure of personal data, violating GDPR requirements and resulting in regulatory penalties. Additionally, attackers could alter or delete critical event data, disrupting business operations and damaging client trust. The availability impact could also lead to denial of service, affecting service continuity. Given the critical nature of the vulnerability and the lack of authentication or user interaction requirements, attackers could easily exploit this remotely, increasing the risk to organizations that have not mitigated this issue.

Organizations should immediately audit their use of Wedding Planner v1.0 and isolate affected systems. Since no official patch is available, mitigation should focus on implementing input validation and parameterized queries or prepared statements to prevent SQL injection. Web application firewalls (WAFs) should be configured to detect and block SQL injection attempts targeting the 'id' parameter on /wedding_details.php. Additionally, organizations should monitor logs for suspicious database queries and unusual activity patterns. If possible, restrict external access to the affected application until remediation is complete. Conducting a comprehensive security review of all web applications and applying secure coding practices will help prevent similar vulnerabilities. Finally, organizations should prepare incident response plans in case of exploitation and ensure backups are current and tested for recovery.
