CVE-2025-45321 is a high-severity SQL Injection vulnerability affecting the kashipara Online Service Management Portal version 1.0. The vulnerability exists in the /osms/Requester/Requesterchangepass.php endpoint, specifically via the 'rPassword' parameter. SQL Injection (CWE-89) vulnerabilities allow attackers to inject malicious SQL queries into the backend database through unsanitized input fields. In this case, the 'rPassword' parameter is not properly sanitized or parameterized, enabling an attacker with at least low privileges (PR:L) to execute arbitrary SQL commands remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability of the system, as indicated by the CVSS vector (C:H/I:H/A:H). Exploitation could lead to unauthorized data disclosure, modification, or deletion, and potentially full system compromise if the database is critical to the application. Although no known exploits are currently in the wild, the high CVSS score of 8.8 reflects the significant risk posed by this vulnerability. The lack of available patches or vendor information increases the urgency for organizations using this portal to implement mitigations. Given the nature of the portal as an online service management system, attackers could leverage this vulnerability to escalate privileges, access sensitive user data, or disrupt service operations.

For European organizations using the kashipara Online Service Management Portal, this vulnerability poses a substantial risk. The SQL Injection flaw could lead to unauthorized access to sensitive personal or organizational data, violating GDPR and other data protection regulations, potentially resulting in heavy fines and reputational damage. The ability to alter or delete data threatens operational integrity and availability, which could disrupt business processes and service delivery. Since the vulnerability requires only low privileges and no user interaction, it lowers the barrier for exploitation by internal or external threat actors. European entities relying on this portal for service management may face data breaches, service outages, and compliance violations. Additionally, the exposure of internal systems through this vulnerability could be leveraged for lateral movement within networks, increasing the scope of potential damage.

1. Immediate implementation of input validation and parameterized queries for the 'rPassword' parameter to prevent SQL Injection. 2. Conduct a thorough code review of the entire application to identify and remediate similar injection points. 3. Deploy Web Application Firewalls (WAF) with custom rules to detect and block SQL Injection attempts targeting the vulnerable endpoint. 4. Restrict database user permissions to the minimum necessary to limit the impact of potential exploitation. 5. Monitor logs for suspicious database queries or unusual activity related to the /osms/Requester/Requesterchangepass.php endpoint. 6. If possible, isolate the affected portal in a segmented network zone to reduce lateral movement risk. 7. Engage with the vendor or development team to obtain or develop a security patch and apply it promptly once available. 8. Educate internal users about the risks and signs of exploitation attempts to enhance detection capabilities.
