📋 TL;DR
An insecure direct object reference (IDOR) vulnerability in PHPGurukul Online Birth Certificate System v1.0 allows authenticated users to access other users' birth certificate details by manipulating the viewid parameter. This affects all installations of version 1.0 where users have authenticated access to the system.
💻 Affected Systems
- PHPGurukul Online Birth Certificate System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all birth certificate data in the system, leading to privacy violations and potential identity theft.
Likely Case
Unauthorized access to sensitive personal information of other users, violating privacy regulations.
If Mitigated
Limited exposure if proper access controls and parameter validation are implemented.
🎯 Exploit Status
Exploitation requires authenticated access but is trivial via URL parameter manipulation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
No official patch available. Implement proper authorization checks in /user/view-application-detail.php to validate user permissions before displaying data.
🔧 Temporary Workarounds
Implement Authorization Check
allAdd server-side authorization validation to ensure users can only access their own data.
Modify /user/view-application-detail.php to check if the requested viewid belongs to the authenticated user before processing.
Use Indirect Reference Maps
allReplace direct object references with indirect references or tokens that cannot be easily enumerated.
Implement a mapping system where users access data via unique tokens rather than sequential IDs.
🧯 If You Can't Patch
- Restrict access to the vulnerable endpoint using web application firewall rules or network segmentation.
- Implement additional logging and monitoring for unauthorized access attempts to the view-application-detail.php endpoint.
🔍 How to Verify
Check if Vulnerable:
As an authenticated user, attempt to access /user/view-application-detail.php with a modified viewid parameter to see if you can view another user's data.Check Version:
Check the system version in the application interface or configuration files.Verify Fix Applied:
Test that authenticated users can only access their own data by attempting to view other users' data with modified viewid parameters.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authorization attempts for view-application-detail.php
- Access to view-application-detail.php with viewid parameters outside expected user range
Network Indicators:
- Unusual patterns of requests to view-application-detail.php with sequential viewid values
SIEM Query:
source="web_logs" AND uri="/user/view-application-detail.php" AND viewid NOT IN (authorized_user_ids)
