CVE-2026-4241 is a SQL Injection vulnerability identified in itsourcecode College Management System version 1.0, specifically within the /admin/time-table.php file. The vulnerability arises due to insufficient input validation and sanitization of the course_code parameter, which is used in SQL queries without proper escaping or parameterization. This allows attackers to craft malicious input that alters the intended SQL query logic, potentially enabling unauthorized retrieval, modification, or deletion of database records. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing its risk profile. The CVSS 4.0 base score is 5.3 (medium), reflecting the moderate impact and ease of exploitation. Although no known exploits are currently active in the wild, public exploit code is available, facilitating potential attacks. The vulnerability affects only version 1.0 of the product, and no official patches have been published yet. The attack surface is limited to the administrative time-table management functionality, but successful exploitation could compromise sensitive academic scheduling and related data. The lack of authentication requirement means attackers can attempt exploitation directly over the network, emphasizing the need for immediate mitigation.

The impact of CVE-2026-4241 includes unauthorized access to sensitive academic and administrative data stored in the College Management System's backend database. Attackers could extract confidential information such as course schedules, student records, or staff details. They might also modify or delete critical data, disrupting academic operations and causing data integrity issues. Availability could be affected if attackers execute destructive SQL commands or cause database errors. The vulnerability's remote exploitability without authentication increases the risk of widespread attacks, especially in environments where the system is exposed to the internet or untrusted networks. Educational institutions relying on this software could face operational disruptions, reputational damage, and potential regulatory compliance issues related to data breaches. The availability of public exploit code further elevates the threat, potentially enabling less skilled attackers to exploit the vulnerability.

To mitigate CVE-2026-4241, organizations should immediately restrict access to the /admin/time-table.php interface to trusted internal networks or VPNs to reduce exposure. Implement web application firewall (WAF) rules specifically targeting SQL injection patterns on the course_code parameter. Conduct thorough input validation and sanitization by applying parameterized queries or prepared statements in the application code to prevent injection. If source code access is available, refactor the vulnerable function to use secure coding practices for database interactions. Monitor logs for suspicious SQL query patterns or repeated access attempts to the vulnerable endpoint. Since no official patch is currently available, consider isolating or disabling the affected module temporarily if feasible. Educate administrators about the risk and ensure regular backups of the database to enable recovery in case of data corruption or deletion. Finally, maintain vigilance for any future patches or advisories from the vendor and apply them promptly.
