CVE-2024-44640
📋 TL;DR
CVE-2024-44640 is an SQL injection vulnerability in PHPGurukul Student Record System that allows attackers to manipulate database queries through course-related parameters. This affects administrators and users of version 3.20 who can access the add-course.php functionality. Successful exploitation could lead to unauthorized data access or manipulation.
💻 Affected Systems
- PHPGurukul Student Record System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including sensitive student records, administrative credentials theft, and potential remote code execution through database functions.
Likely Case
Unauthorized access to student records, course data manipulation, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
SQL injection via course-short, course-full, and cdate parameters requires basic web application testing knowledge. Authentication is typically required to access the vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/student-record-system-php
Restart Required: No
Instructions:
1. Check vendor website for updated version. 2. If no patch available, implement parameterized queries in add-course.php. 3. Validate and sanitize all user inputs for course-short, course-full, and cdate parameters.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to reject malicious input in course parameters
Modify add-course.php to include: $course_short = mysqli_real_escape_string($conn, $_POST['course-short']);
Add length and character type validation for all parameters
Web Application Firewall Rules
allBlock SQL injection patterns targeting the vulnerable parameters
Add WAF rule: Detect SQL keywords in course-short, course-full, cdate parameters
Block requests containing UNION, SELECT, INSERT, DELETE, DROP in parameter values
🧯 If You Can't Patch
- Implement network segmentation to restrict access to the Student Record System
- Enable detailed logging and monitoring for SQL injection attempts on add-course.php
🔍 How to Verify
Check if Vulnerable:
Test add-course.php endpoint with SQL injection payloads in course-short, course-full, or cdate parameters and observe database errors or unexpected behavior.Check Version:
Check PHPGurukul Student Record System version in admin panel or system configuration files.Verify Fix Applied:
Attempt SQL injection tests after implementing fixes and verify no database errors or unauthorized data access occurs.📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database queries from add-course.php
- Multiple failed login attempts followed by course parameter manipulation
Network Indicators:
- HTTP POST requests to add-course.php with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/add-course.php" AND (param="course-short" OR param="course-full" OR param="cdate") AND (value="UNION" OR value="SELECT" OR value="INSERT" OR value="--" OR value="' OR '")
