CVE-2026-1545

7.3 HIGH

📋 TL;DR

CVE-2026-1545 is a SQL injection vulnerability in itsourcecode School Management System 1.0 that allows remote attackers to execute arbitrary SQL commands via the ID parameter in /course/index.php. This can lead to unauthorized data access, modification, or deletion. All deployments of version 1.0 are affected.

💻 Affected Systems

Products:
  • itsourcecode School Management System
Versions: 1.0
Operating Systems: All platforms running PHP
Default Config Vulnerable: ⚠️ Yes
Notes: All installations of version 1.0 are vulnerable; no special configuration required

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise including sensitive student/teacher data theft, system takeover via RCE, and data destruction

🟠

Likely Case

Data exfiltration of sensitive information, privilege escalation, and unauthorized system access

🟢

If Mitigated

Limited impact with proper input validation and WAF protection, potentially only error-based information disclosure

🌐 Internet-Facing: HIGH - Remote exploitation without authentication makes internet-facing instances extremely vulnerable
🏢 Internal Only: MEDIUM - Internal attackers could exploit but require network access; still significant risk

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Public exploit available; SQL injection via ID parameter requires minimal technical skill

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://itsourcecode.com/

Restart Required: No

Instructions:

No official patch available. Consider migrating to alternative software or implementing workarounds.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Add parameterized queries and input validation to /course/index.php

Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM courses WHERE id = ?'); $stmt->bind_param('i', $id);

Web Application Firewall Rules

all

Block SQL injection patterns targeting /course/index.php

Add WAF rule: SecRule REQUEST_URI "@contains /course/index.php" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt detected'"

🧯 If You Can't Patch

  • Isolate the system behind a reverse proxy with strict input filtering
  • Implement network segmentation and restrict access to only authorized users

🔍 How to Verify

Check if Vulnerable:

Test /course/index.php with SQL injection payloads like ' OR '1'='1 in ID parameter

Check Version:

Check PHP files for version markers or consult system documentation

Verify Fix Applied:

Verify that SQL injection payloads no longer execute and return proper error handling

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL errors in application logs
  • Multiple rapid requests to /course/index.php with SQL keywords

Network Indicators:

  • HTTP requests containing SQL injection patterns to vulnerable endpoint

SIEM Query:

source="web_logs" AND uri="/course/index.php" AND (request LIKE "%UNION%" OR request LIKE "%SELECT%" OR request LIKE "%OR%1%1%")
