CVE-2025-2383
📋 TL;DR
This critical SQL injection vulnerability in PHPGurukul Doctor Appointment Management System 1.0 allows attackers to execute arbitrary SQL commands through the searchdata parameter in /doctor/search.php. Attackers can potentially access, modify, or delete sensitive medical appointment data. All installations of version 1.0 with the vulnerable component exposed are affected.
💻 Affected Systems
- PHPGurukul Doctor Appointment Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to exposure of all patient records, appointment details, and potentially administrative credentials, followed by system takeover or data destruction.
Likely Case
Unauthorized access to sensitive patient appointment data, potential extraction of database contents, and possible privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing without modification.
🎯 Exploit Status
Exploit details are publicly available on GitHub. Attack requires network access to the vulnerable endpoint but no authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and parameterized queries in the search.php file, or migrate to a different system.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize the searchdata parameter before processing SQL queries.
Edit /doctor/search.php to implement proper input validation using PHP's filter_var() or custom regex patterns
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests.
🧯 If You Can't Patch
- Block external access to /doctor/search.php via firewall rules or web server configuration
- Implement database user with minimal privileges (read-only if possible) for the application
🔍 How to Verify
Check if Vulnerable:
Test the /doctor/search.php endpoint with SQL injection payloads in the searchdata parameter (e.g., searchdata=' OR '1'='1). Monitor for unexpected database responses or errors.
Check Version:
Check the system version in the application's admin panel or configuration files, typically found in config.php or similar files.
Verify Fix Applied:
After implementing fixes, retest with the same payloads to ensure they are properly blocked or sanitized without executing SQL commands.
📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple rapid requests to /doctor/search.php with suspicious parameters
- Database query logs showing unexpected SQL commands
Network Indicators:
- HTTP POST/GET requests to /doctor/search.php containing SQL keywords (UNION, SELECT, INSERT, etc.) in parameters
- Abnormal traffic patterns to the vulnerable endpoint
SIEM Query:
source="web_server_logs" AND (url_path="/doctor/search.php" AND (param="searchdata" AND value MATCHES "(?i)(union|select|insert|update|delete|drop|or|and|'|--|#)"))
