CVE-2025-63622 identifies a critical SQL injection vulnerability in the Online Complaint Site 1.0, specifically within the /cms/admin/subcategory.php script. The vulnerability stems from improper handling of the 'category' parameter, which is directly used in SQL queries without adequate sanitization or parameterization. This flaw allows an attacker to inject malicious SQL code, potentially enabling unauthorized access to the backend database, data exfiltration, modification, or deletion of records. The vulnerability is located in an administrative component, which may require some level of access, but the exact authentication requirements are unspecified. No CVSS score has been assigned yet, and no public exploits have been reported, indicating it may be newly discovered or not yet widely exploited. The lack of patch links suggests that a fix is not yet publicly available, increasing the urgency for affected organizations to implement mitigations. SQL injection remains one of the most severe web application vulnerabilities due to its impact on confidentiality, integrity, and availability of data. Attackers exploiting this vulnerability could compromise sensitive complaint data, disrupt service operations, or pivot to further internal network compromise. The vulnerability's presence in a complaint management system indicates potential exposure of personal or sensitive user data, raising compliance and reputational risks.

For European organizations, exploitation of this SQL injection vulnerability could lead to significant data breaches involving personal or sensitive complaint information, violating GDPR and other data protection regulations. The integrity of complaint records could be compromised, undermining trust in organizational processes. Availability of the complaint management system could be disrupted, affecting customer service and operational continuity. Organizations handling large volumes of citizen or customer complaints, especially in public sector or regulated industries, face heightened risks. The exposure of sensitive data could result in legal penalties, financial losses, and reputational damage. Additionally, attackers could leverage this vulnerability as a foothold for lateral movement within organizational networks, increasing the scope of potential damage. The absence of known exploits suggests a window of opportunity for proactive defense, but also a risk of rapid exploitation once publicized. European entities relying on similar CMS platforms or custom complaint management solutions should consider this vulnerability indicative of broader risks in their web application security posture.

Organizations should immediately audit their use of the Online Complaint Site 1.0 software or any similar CMS platforms for the presence of the vulnerable /cms/admin/subcategory.php component. Implement strict input validation and sanitization on the 'category' parameter, preferably using parameterized queries or prepared statements to prevent SQL injection. Conduct a comprehensive code review focusing on all user-supplied inputs in administrative modules. If possible, restrict access to the administrative interface via network segmentation, VPNs, or IP whitelisting to reduce exposure. Monitor logs for unusual SQL errors or suspicious query patterns indicative of injection attempts. Apply web application firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting this endpoint. Engage with the software vendor or community to obtain patches or updates addressing this vulnerability. Educate developers and administrators on secure coding practices and the risks of SQL injection. Finally, maintain regular backups of complaint data to enable recovery in case of data corruption or deletion.
