CVE-2026-6595: SQL Injection in ProjectsAndPrograms School Management System

CVE-2026-6595: SQL Injection in School Management System Bus Location Handler

A SQL injection vulnerability assigned CVE-2026-6595 has been disclosed in ProjectsAndPrograms School Management System affecting all versions up to commit 6b6fae5426044f89c08d0dd101c7fa71f9042a59. The vulnerability resides in buslocation.php and is triggered via the HTTP GET parameter bus_id, which is passed into a SQL query without sanitization.

The flaw carries a CVSS v3.1 score of 7.3 (Medium) and is classified under CWE-89 — Improper Neutralization of Special Elements used in SQL Commands (SQL Injection).

Vulnerability Overview

Technical Details

Affected Component

The vulnerability is located in the bus location tracking module of the School Management System at buslocation.php. The bus_id GET parameter is used to retrieve bus location data from the database but is not validated or parameterized before inclusion in the SQL query.

Exploitation Mechanism

An attacker can inject SQL syntax directly into the bus_id GET parameter to manipulate query logic:

GET /buslocation.php?bus_id=1' UNION SELECT NULL,table_name,NULL FROM information_schema.tables-- HTTP/1.1

Successful exploitation can enable:

• Database enumeration — identifying all tables, columns, and schema structure
• Data extraction — dumping student records, staff information, bus schedules, and contact data
• Credential harvesting — extracting hashed passwords for admin or staff accounts
• Data manipulation — updating or deleting bus location records

Exploit Availability

The vulnerability was published to NVD on 2026-04-20 with a public disclosure. No CVSSv3 environmental score has been assigned, but the base score of 7.3 reflects meaningful exploitability via network access.

Attack Flow

1. Attacker identifies a publicly accessible School Management System instance

2. Attacker locates buslocation.php and the bus_id GET parameter

3. Attacker injects SQL payloads into the bus_id parameter

4. The application passes the unsanitized input directly to the backend database

5. Attacker enumerates tables and extracts sensitive student, staff, and admin data

6. With harvested admin credentials, attacker gains privileged access to the system

Affected Data

School management systems typically store sensitive data including:

• Student records — personal information, enrollment status, schedules
• Staff and faculty data — employee records, login credentials
• Transportation data — bus routes, student pickup/drop-off information, guardian contact details
• Administrative accounts — credentials used to manage the platform

A successful SQL injection attack could expose all of this data to an unauthenticated remote attacker.

Remediation

No official patch has been released for CVE-2026-6595. The following mitigations should be applied immediately to any production deployment:

Input Validation

Replace all direct parameter interpolation with parameterized queries:

// Vulnerable pattern
$result = mysqli_query($conn, "SELECT * FROM bus_location WHERE bus_id = " . $_GET['bus_id']);
 
// Secure pattern
$stmt = $conn->prepare("SELECT * FROM bus_location WHERE bus_id = ?");
$stmt->bind_param("i", $_GET['bus_id']);
$stmt->execute();

Access Restriction

1. Restrict public access — ensure school management pages are not exposed directly to the internet
2. Require authentication for all transport-related endpoints including buslocation.php
3. Apply WAF rules to block common SQL injection patterns (UNION, SELECT, DROP, --)

Detection

Review web server logs for suspicious payloads targeting buslocation.php:

grep "buslocation.php" /var/log/apache2/access.log | grep -i "union\|select\|drop\|--\|'"

Impact Assessment

Key Takeaways

1. CVE-2026-6595 is a CVSS 7.3 SQL injection in ProjectsAndPrograms School Management System, affecting buslocation.php
2. The bus_id HTTP GET parameter is passed unsanitized into a database query
3. No official patch exists — apply parameterized queries and restrict endpoint access immediately
4. School management systems handle sensitive student and family data, making breaches particularly impactful
5. This follows a broader pattern of SQL injection disclosures against PHP-based school and education management systems
