CVE-2025-50492
📋 TL;DR
This vulnerability allows attackers to hijack user sessions in PHPGurukul e-Diary Management System by exploiting improper session invalidation during password changes. Attackers can maintain access to accounts even after password changes, affecting all users of the vulnerable system.
💻 Affected Systems
- PHPGurukul e-Diary Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain persistent unauthorized access to any user account, potentially compromising sensitive diary data, performing unauthorized actions, or escalating privileges.
Likely Case
Attackers hijack active sessions to access user accounts, view private information, and potentially modify data within the e-diary system.
If Mitigated
Limited impact with proper session management controls, but still presents authentication bypass risk for affected sessions.
🎯 Exploit Status
Exploitation requires access to valid session tokens. Public GitHub repository contains proof-of-concept details.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check vendor website for updates. 2. If patch available, download and replace affected files. 3. Verify session invalidation occurs properly on password change.
🔧 Temporary Workarounds
Manual Session Invalidation
allModify change-password.php to properly invalidate all existing sessions when password changes
Edit /edms/change-password.php to add session_destroy() and regenerate session ID after password change
Access Restriction
allRestrict access to the vulnerable component
Add IP whitelisting or additional authentication to /edms/change-password.php
🧯 If You Can't Patch
- Implement network segmentation to isolate the e-Diary system
- Enable detailed session logging and monitoring for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Test if session remains active after changing password. If you can still access the system with old session token after password change, system is vulnerable.Check Version:
Check system documentation or admin panel for version informationVerify Fix Applied:
After applying fix, verify that all sessions are invalidated when password changes. Old session tokens should no longer provide access.📡 Detection & Monitoring
Log Indicators:
- Multiple successful logins from same user from different locations
- Password change events without corresponding session termination
Network Indicators:
- Unusual access patterns to /edms/change-password.php
- Multiple sessions for single user account
SIEM Query:
source="web_logs" AND (uri="/edms/change-password.php" OR event="password_change") | stats count by user, session_id
