CVE-2023-5010 is a high-severity SQL Injection vulnerability (CWE-89) found in version 1.0 of the Kashipara Group Student Information System. The vulnerability exists in the 'coursecode' parameter of the marks.php resource, which does not properly validate or sanitize user input before incorporating it into SQL queries. This improper neutralization of special elements allows an authenticated user with at least limited privileges (PR:L) to inject malicious SQL commands directly into the backend database. The vulnerability has a CVSS 3.1 base score of 8.8, indicating a high impact on confidentiality, integrity, and availability. Exploitation requires network access (AV:N), low attack complexity (AC:L), and no user interaction (UI:N). The scope is unchanged (S:U), meaning the impact is confined to the vulnerable component. Successful exploitation could lead to unauthorized data disclosure, modification, or deletion of student records and other sensitive information stored in the database. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the critical nature of the data handled by student information systems and the ease of exploitation once authenticated. The lack of input validation on the 'coursecode' parameter makes it a straightforward target for attackers who have valid credentials, potentially including disgruntled insiders or compromised accounts. Given the sensitive nature of educational data, this vulnerability could also facilitate further attacks such as privilege escalation or lateral movement within the affected environment.

For European organizations, particularly educational institutions using the Kashipara Group Student Information System, this vulnerability could lead to severe data breaches involving student personal information, academic records, and potentially financial data. The compromise of such data could result in violations of the EU General Data Protection Regulation (GDPR), leading to substantial fines and reputational damage. Additionally, the integrity of academic records could be undermined, affecting institutional credibility and student outcomes. The availability impact could disrupt administrative operations, causing delays in grading and record-keeping. Since exploitation requires authentication, the threat is heightened if credential management is weak or if insider threats exist. The vulnerability could also be leveraged as a foothold for broader network compromise, especially in interconnected university IT environments. Given the increasing reliance on digital student management systems across Europe, the potential operational and compliance impacts are significant.

To mitigate this vulnerability, organizations should immediately apply any available patches or updates from Kashipara Group once released. In the absence of official patches, implement strict input validation and sanitization on the 'coursecode' parameter to ensure only expected alphanumeric characters or predefined course codes are accepted. Employ parameterized queries or prepared statements in the application code to prevent SQL injection. Restrict database user privileges associated with the application to the minimum necessary, avoiding excessive permissions that could amplify damage if exploited. Implement robust authentication mechanisms, including multi-factor authentication, to reduce the risk of credential compromise. Monitor application logs for unusual SQL query patterns or failed injection attempts. Conduct regular security assessments and code reviews focusing on input handling. Additionally, segment the network to limit access to the student information system and its database, and maintain up-to-date backups to enable recovery in case of data tampering or loss.
