CVE-2025-13581 is an SQL injection vulnerability identified in the itsourcecode Student Information System version 1.0. The vulnerability exists in the /schedule_edit1.php file, where the schedule_id parameter is improperly sanitized, allowing attackers to inject malicious SQL code. This injection flaw enables remote attackers to manipulate backend database queries without requiring authentication or user interaction, potentially leading to unauthorized data retrieval, modification, or deletion. The vulnerability has a CVSS 4.0 base score of 5.3, indicating medium severity, with a vector showing network attack vector, low attack complexity, no privileges or user interaction required, and low impact on confidentiality, integrity, and availability. Although no active exploits are reported in the wild, a public exploit is available, increasing the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is used primarily in educational environments to manage student information and scheduling. The lack of patches or official remediation guidance necessitates immediate defensive measures. The vulnerability's exploitation could compromise sensitive student data, disrupt scheduling operations, and potentially allow attackers to pivot within the network. Given the nature of SQL injection, attackers could escalate the impact by extracting credentials or injecting further malicious commands. The vulnerability's presence in a critical educational system underscores the importance of timely mitigation to protect data privacy and system integrity.

For European organizations, particularly educational institutions using the itsourcecode Student Information System version 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of student data and scheduling information. Exploitation could lead to unauthorized disclosure of personal and academic records, manipulation of schedules, or disruption of administrative operations. This could result in regulatory non-compliance under GDPR due to exposure of personal data, reputational damage, and operational downtime. The remote and unauthenticated nature of the attack vector increases the likelihood of exploitation, especially in environments with internet-facing instances of the software. Additionally, attackers could leverage this vulnerability as a foothold for lateral movement within institutional networks, potentially compromising broader IT infrastructure. The medium severity rating suggests a moderate but tangible risk that requires prompt attention to prevent escalation or data breaches.

To mitigate CVE-2025-13581, organizations should immediately implement input validation and sanitization on the schedule_id parameter to prevent SQL injection. Employing parameterized queries or prepared statements is critical to ensure that user input cannot alter SQL command structure. If source code modification is not feasible, deploying a Web Application Firewall (WAF) with specific rules to detect and block SQL injection attempts targeting /schedule_edit1.php can provide a temporary safeguard. Restricting access to the vulnerable endpoint by IP whitelisting or VPN access can reduce exposure. Regularly monitoring logs for suspicious query patterns or repeated access attempts to schedule_edit1.php will aid in early detection of exploitation attempts. Organizations should also inventory their software versions to identify affected instances and prioritize updates or migration to newer, patched versions once available. Finally, conducting security awareness training for administrators on the risks of SQL injection and ensuring secure coding practices in future development will help prevent recurrence.
