CVE-2026-10302: SQL Injection in itsourcecode Fees Management System 1.0

Technical summary

CVE-2026-10302 is a SQL injection flaw (CWE-89) stemming from improper input validation (CWE-74) in an unspecified function of /manage_fee.php. The ID parameter is not properly sanitized before being incorporated into SQL queries. An attacker with valid authentication credentials can craft a malicious ID value to break out of the intended query context and execute arbitrary SQL commands. The CVSS 3.1 score of 6.3 (Medium) reflects the requirement for prior authentication; without it, the attack surface is eliminated. The network-accessible nature of the web application means exploitation can occur from any location.

Business impact

Successful exploitation could result in unauthorized disclosure of sensitive fee records, student information, payment details, or other confidential data stored in the application database. Attackers could also modify or delete records, disrupting billing processes, academic records, or fee tracking. While the MEDIUM severity score suggests limited immediate damage compared to critical vulnerabilities, a compromised fees management system can erode institutional trust and trigger compliance violations (FERPA, data protection regulations).

Affected systems

itsourcecode Fees Management System version 1.0 is affected. Organizations running this specific version in production environments are at risk if any user accounts have been compromised or if insider threats are a concern. Cloud or self-hosted deployments of this system are equally vulnerable.

Exploitability

The vulnerability is exploitable but not trivial. It requires an authenticated user session, meaning the attacker must either possess or compromise valid credentials. However, public disclosure and available proof-of-concept code lower the barrier to exploitation. Common weak credential management (shared accounts, default passwords) could enable attackers to gain initial access. Once authenticated, crafting SQL injection payloads requires moderate technical skill but is well-documented in security literature.

Remediation

The primary remediation is to upgrade to a patched version of itsourcecode Fees Management System. Verify against the vendor's official advisory for the specific version number. Pending patching, implement input validation on the ID parameter using allowlists (e.g., accept only numeric values if IDs are numeric), employ parameterized queries or prepared statements in the application code, and enforce the principle of least privilege on database accounts used by the application. Additionally, enforce strong credential policies and monitor authentication logs for suspicious activity.

Patch guidance

Contact itsourcecode for patch availability and version information, as no specific patched version is identified in current advisories. Apply updates through the vendor's official channels. Test patches in a staging environment before production deployment to ensure compatibility with dependent systems. Document the patch version applied for audit and compliance purposes.

Detection guidance

Monitor application logs for SQL syntax errors or unusual query patterns in /manage_fee.php requests. Network intrusion detection systems can flag suspicious SQL keywords (UNION, SELECT, OR 1=1, etc.) in URL parameters. Database activity monitoring (DAM) tools should alert on unexpected command execution or privilege escalation attempts. Review access logs for authenticated users accessing the /manage_fee.php endpoint with unusual ID parameter values. Implement Web Application Firewalls (WAF) with SQL injection signatures to block malicious requests at the perimeter.

Why prioritize this

While the CVSS score is MEDIUM, this vulnerability should be prioritized because: (1) public exploit code exists, lowering barriers to attack; (2) it targets a core financial system, impacting data integrity and institutional operations; (3) unauthorized data access could trigger regulatory incidents; (4) authentication requirement narrows but does not eliminate risk, particularly in environments with weak credential controls. Organizations should patch within 30 days.

Risk score, explained

The CVSS 3.1 score of 6.3 (MEDIUM) reflects: Network Accessible (AV:N) — exploitable remotely; Low Complexity (AC:L) — no special conditions needed; Requires Logged-In User (PR:L) — authentication is mandatory; No User Interaction (UI:N) — automatic once authenticated; Limited Scope (S:U) — impact confined to the vulnerable component; Low Confidentiality, Integrity, and Availability Impact (C:L/I:L/A:L) — data can be read, modified, or deleted but not with catastrophic system-wide effect. The authentication requirement prevents a critical rating; however, the scope of impact on financial data justifies close monitoring.
