CVE-2025-5599
📋 TL;DR
A critical SQL injection vulnerability in PHPGurukul Student Result Management System 1.3 allows remote attackers to execute arbitrary SQL commands via the emp1ctc parameter in /editmyexp.php. This affects all systems running the vulnerable version of this software, potentially compromising database integrity and confidentiality.
💻 Affected Systems
- PHPGurukul Student Result Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized data access and extraction of sensitive student/employee information, potentially leading to data breaches.
If Mitigated
Limited impact with proper input validation and database permissions, though SQL injection attempts would still be logged.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily weaponizable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify /editmyexp.php to implement proper input validation and use prepared statements with parameterized queries.
Edit /editmyexp.php to replace direct SQL concatenation with PDO or mysqli prepared statements
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block exploitation attempts.
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules to only allow trusted IP addresses.
- Implement database user with minimal privileges (read-only if possible) for the application connection.
🔍 How to Verify
Check if Vulnerable:
Check if /editmyexp.php exists and contains unsanitized emp1ctc parameter usage in SQL queries. Test with SQL injection payloads like ' OR '1'='1.Check Version:
Check version in application files or database configuration; look for version 1.3 indicators in source code.Verify Fix Applied:
Test the emp1ctc parameter with SQL injection payloads; successful fix should return error messages or no data manipulation.📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database queries from web application user
- Multiple failed login attempts or parameter manipulation
Network Indicators:
- HTTP requests to /editmyexp.php with SQL keywords in parameters
- Unusual database traffic patterns
SIEM Query:
source="web_server.log" AND uri="/editmyexp.php" AND (param="emp1ctc" AND value CONTAINS "' OR" OR value CONTAINS "UNION" OR value CONTAINS "SELECT")
