CVE-2026-10302: Fees Management System SQLi Vulnerability

CVE-2026-10302 Overview

CVE-2026-10302 is a SQL injection vulnerability in itsourcecode Fees Management System 1.0. The flaw resides in the /manage_fee.php script, where the ID parameter is passed to a database query without proper sanitization. Attackers can manipulate the ID argument to inject arbitrary SQL syntax into the underlying query.

The vulnerability is remotely exploitable over the network and requires low-privilege authentication. A public exploit has been disclosed through VulDB, increasing the likelihood of opportunistic abuse against exposed installations. The flaw is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact

A public exploit exists for an authenticated remote SQL injection in /manage_fee.php, allowing attackers to read, modify, or delete records in the fees management database.

Affected Products

• itsourcecode Fees Management System 1.0
• /manage_fee.php endpoint (vulnerable ID parameter)
• Deployments exposing the application to untrusted networks

Technical Details for CVE-2026-10302

Vulnerability Analysis

The Fees Management System exposes a PHP endpoint at /manage_fee.php that accepts an ID parameter through an HTTP request. The application concatenates the user-supplied ID value directly into a SQL statement instead of using parameterized queries or prepared statements.

An attacker with low-privilege access can append SQL syntax, including UNION SELECT, boolean-based, or time-based payloads, to alter query logic. Successful exploitation enables data exfiltration, modification of fee records, and potential authentication bypass through manipulated query conditions.

The exploit has been published according to VulDB, lowering the technical barrier for attackers. While the CVSS 4.0 score reflects limited impact on confidentiality, integrity, and availability, the public availability of working proof-of-concept code makes opportunistic scanning likely.

Root Cause

The root cause is improper neutralization of special elements within a SQL query [CWE-74]. The manage_fee.php script trusts the ID parameter from the request without applying input validation, type casting, escaping, or prepared statement binding. PHP applications using mysqli or mysql_query with concatenated strings are particularly susceptible to this class of flaw.

Attack Vector

The attack is launched remotely over the network against an authenticated session. An attacker submits a crafted HTTP request to /manage_fee.php with a malicious ID value. The payload modifies the executed SQL statement, returning data outside the intended query scope or altering database state.

No public, verified proof-of-concept code is reproduced here. Refer to the VulDB CVE-2026-10302 entry and the GitHub Issue Discussion for technical disclosure details.

Detection Methods for CVE-2026-10302

Indicators of Compromise

• HTTP requests to /manage_fee.php containing SQL meta-characters such as ', ", --, ;, UNION, SELECT, or SLEEP( in the ID parameter.
• Repeated requests to /manage_fee.php with incrementing or anomalous ID values consistent with enumeration.
• Database error messages logged from the Fees Management System indicating malformed SQL queries.
• Unexpected outbound traffic from the web server to attacker-controlled infrastructure after suspicious requests.

Detection Strategies

• Deploy web application firewall (WAF) rules that flag SQL injection patterns targeting the ID parameter on /manage_fee.php.
• Inspect web server access logs for query strings containing encoded SQL keywords (%27, %20OR%20, %20UNION%20).
• Correlate authentication events with subsequent anomalous database queries to identify low-privilege accounts performing data extraction.

Monitoring Recommendations

• Enable verbose MySQL or MariaDB query logging on databases backing the Fees Management System for forensic review.
• Monitor for spikes in HTTP 500 responses from /manage_fee.php indicating broken SQL syntax during injection probing.
• Alert on anomalous read volumes against fee, student, or user tables outside normal business workflows.

How to Mitigate CVE-2026-10302

Immediate Actions Required

• Restrict access to /manage_fee.php through network segmentation, VPN, or IP allowlisting until a patch is applied.
• Audit application logs for prior exploitation attempts referencing the ID parameter on /manage_fee.php.
• Rotate database credentials and review fee, student, and user records for unauthorized modification.

Patch Information

No official vendor patch is referenced in the NVD entry at the time of publication. Operators should monitor itsourcecode.com and the GitHub Issue Discussion for remediation guidance. Until an official fix is released, apply the workarounds below.

Workarounds

• Modify manage_fee.php to use parameterized queries through mysqli_prepare or PDO with bound parameters for the ID value.
• Enforce strict server-side type validation by casting ID to an integer with (int)$_GET['ID'] before any database operation.
• Deploy a WAF rule blocking requests to /manage_fee.php containing SQL meta-characters in the ID parameter.
• Apply the principle of least privilege to the database account used by the application, removing DROP, ALTER, and cross-database permissions.
