CVE-2025-9689 is a SQL Injection vulnerability identified in version 1.0 of the SourceCodester Advanced School Management System, specifically within an unknown function located at /index.php/stock/item_select. The vulnerability arises from improper sanitization or validation of the 'q' parameter, which an attacker can manipulate to inject malicious SQL code. This flaw allows remote attackers to execute arbitrary SQL queries against the backend database without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:L). The vulnerability has a CVSS 4.0 base score of 5.3, categorizing it as medium severity. Although no public exploits are currently observed in the wild, the exploit code has been made publicly available, increasing the risk of exploitation. The vulnerability impacts the confidentiality, integrity, and availability of the affected system's data, as attackers could potentially extract sensitive information, modify or delete records, or disrupt system operations. The scope is limited to installations running version 1.0 of this specific school management system. The vulnerability does not require user interaction but does require low privileges (PR:L), suggesting that an attacker might need some level of access or that the system has weak privilege separation. No patches or fixes have been linked yet, indicating that organizations using this software need to apply mitigations proactively.

For European organizations, particularly educational institutions using the SourceCodester Advanced School Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of student and staff data, including personal information, academic records, and financial details. Exploitation could lead to unauthorized data disclosure, data tampering, or denial of service, disrupting school operations and potentially violating GDPR regulations due to data breaches. The medium severity score reflects moderate ease of exploitation combined with impactful consequences. Given the remote exploitability and lack of required user interaction, attackers could automate attacks at scale, targeting multiple institutions. This could result in reputational damage, regulatory penalties, and operational downtime. Additionally, since the system is specialized for school management, the impact on availability could hinder critical administrative functions, affecting teaching and learning processes.

Organizations should immediately audit their use of the SourceCodester Advanced School Management System to identify any instances of version 1.0 in deployment. Since no official patches are currently available, administrators should consider the following specific mitigations: 1) Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'q' parameter in /index.php/stock/item_select. 2) Restrict network access to the management system to trusted IP addresses or VPNs to limit exposure. 3) Conduct input validation and sanitization at the application or proxy level to neutralize malicious input. 4) Monitor logs for unusual query patterns or repeated access attempts to the vulnerable endpoint. 5) If feasible, upgrade to a newer, patched version of the software once available or consider migrating to alternative school management solutions with better security track records. 6) Educate IT staff on the vulnerability and ensure incident response plans include steps for SQL injection attacks. 7) Regularly back up databases and test restoration procedures to minimize data loss in case of compromise.
