CVE-2025-7176
📋 TL;DR
This critical SQL injection vulnerability in PHPGurukul Hospital Management System 1.0 allows remote attackers to execute arbitrary SQL commands via the viewid parameter in view-medhistory.php. This can lead to unauthorized data access, modification, or deletion. All systems running the vulnerable version are affected.
💻 Affected Systems
- PHPGurukul Hospital Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including patient medical records, administrative credentials, and system takeover leading to data breach and service disruption.
Likely Case
Unauthorized access to sensitive patient data, potential data manipulation, and privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or limited data exposure.
🎯 Exploit Status
Exploit details publicly available on GitHub. SQL injection via GET parameter makes exploitation straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and parameterized queries manually.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize the viewid parameter before processing
Modify view-medhistory.php to validate viewid as integer: if(!is_numeric($_GET['viewid'])) { die('Invalid input'); }
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns
Add WAF rule: SecRule ARGS:viewid "@rx (?i)(union|select|insert|update|delete|drop|--|#|\/\*|\*\/)" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt'" (ModSecurity example)
🧯 If You Can't Patch
- Isolate the system from internet access and restrict internal network access
- Implement strict database permissions and monitor for unusual SQL queries
🔍 How to Verify
Check if Vulnerable:
Test by accessing view-medhistory.php with SQL injection payload: /view-medhistory.php?viewid=1' OR '1'='1Check Version:
Check application files for version information or review source code commentsVerify Fix Applied:
Test with same payload after fixes - should return error or sanitized response instead of executing SQL📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed parameter validation attempts
- Requests with SQL keywords in viewid parameter
Network Indicators:
- HTTP requests containing SQL injection patterns in GET parameters
- Unusual database query patterns from application server
SIEM Query:
source="web_logs" AND (uri="*view-medhistory.php*" AND (query="*union*" OR query="*select*" OR query="*' OR '*"))
