CVE-2025-6322
📋 TL;DR
CVE-2025-6322 is a critical SQL injection vulnerability in PHPGurukul Pre-School Enrollment System 1.0 that allows remote attackers to execute arbitrary SQL commands via the 'gname' parameter in the /visit.php file. This affects all installations of version 1.0, potentially compromising the entire database. Attackers can exploit this without authentication to steal, modify, or delete sensitive student and administrative data.
💻 Affected Systems
- PHPGurukul Pre-School Enrollment System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, and potential remote code execution if database permissions allow file system access or command execution.
Likely Case
Unauthorized access to sensitive student records, personal information, and administrative credentials stored in the database.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, with database running with minimal privileges.
🎯 Exploit Status
Exploit code is publicly available on GitHub. The vulnerability requires no authentication and has simple exploitation vectors.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
1. Check vendor website for security updates. 2. If no patch is available, implement workarounds immediately. 3. Consider migrating to alternative software if vendor does not provide timely fixes.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd input validation and parameterized queries to the /visit.php file to prevent SQL injection.
Edit /visit.php and replace direct variable usage with prepared statements: $stmt = $conn->prepare('SELECT * FROM table WHERE gname = ?'); $stmt->bind_param('s', $gname); $stmt->execute();
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting the /visit.php endpoint.
Add WAF rule: Block requests to /visit.php containing SQL keywords like UNION, SELECT, INSERT, UPDATE, DELETE, DROP, OR, AND in gname parameter.
🧯 If You Can't Patch
- Immediately restrict access to /visit.php using network ACLs or firewall rules to only trusted IP addresses.
- Implement database monitoring and alerting for unusual SQL queries originating from the application.
🔍 How to Verify
Check if Vulnerable:
Test the /visit.php endpoint with SQL injection payloads in the gname parameter (e.g., gname=' OR '1'='1). If the application returns database errors or unexpected data, it is vulnerable.Check Version:
Check the software version in the application's admin panel or configuration files. Look for version 1.0 in source code or documentation.Verify Fix Applied:
After applying fixes, retest with the same SQL injection payloads. The application should return proper error messages or no data without executing SQL commands.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs containing SQL syntax from /visit.php requests.
- Multiple failed login attempts or database queries with suspicious patterns in gname parameter.
Network Indicators:
- HTTP requests to /visit.php with SQL keywords in URL parameters or POST data.
- Unusual database traffic patterns from the application server.
SIEM Query:
source="web_logs" AND uri_path="/visit.php" AND (param_gname CONTAINS "UNION" OR param_gname CONTAINS "SELECT" OR param_gname CONTAINS "OR 1=1")
