CVE-2024-42768
📋 TL;DR
A Cross-Site Request Forgery (CSRF) vulnerability in Kashipara Hotel Management System v1.0 allows attackers to trick authenticated administrators into performing unauthorized actions, specifically deleting rooms via the /admin/delete_room.php endpoint. This affects all installations of version 1.0 where administrators access the system while logged into malicious sites. The vulnerability requires an authenticated admin session but no direct interaction with the malicious request.
💻 Affected Systems
- Kashipara Hotel Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could delete all room data from the hotel management system, causing operational disruption, data loss, and requiring restoration from backups.
Likely Case
Targeted deletion of specific rooms or room categories, leading to booking system errors and administrative overhead to restore data.
If Mitigated
With proper CSRF protections, no unauthorized actions can be performed even if administrators visit malicious sites.
🎯 Exploit Status
Exploitation requires the victim admin to be logged into the hotel management system and visit a malicious webpage. The GitHub reference contains proof-of-concept details.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Implement CSRF tokens on all state-changing endpoints, particularly /admin/delete_room.php. Validate that each POST request includes a unique, unpredictable token tied to the user session.
🔧 Temporary Workarounds
Implement CSRF Protection Middleware
allAdd CSRF token validation to all admin endpoints before processing requests.
Modify PHP files to include CSRF token generation and validation. Example: Add session-based token generation in login and validation in delete_room.php.
Restrict Admin Access
linuxLimit admin panel access to specific IP addresses or internal networks only.
Add .htaccess rules: Order Deny,Allow
Deny from all
Allow from 192.168.1.0/24
Configure web server (Apache/Nginx) access controls for /admin directory.
🧯 If You Can't Patch
- Implement network segmentation to isolate the hotel management system from general user networks.
- Use browser extensions that block CSRF attempts or enforce same-origin policies for admin sessions.
🔍 How to Verify
Check if Vulnerable:
Review /admin/delete_room.php source code for absence of CSRF token validation. Test by creating a simple HTML form that submits a POST request to delete_room.php and checking if it succeeds without proper tokens.Check Version:
Check system documentation or configuration files for version information. No standard command; review application files or interface.Verify Fix Applied:
After implementing CSRF tokens, test that unauthorized POST requests without valid tokens are rejected with an error (e.g., 403 Forbidden).📡 Detection & Monitoring
Log Indicators:
- Multiple DELETE room requests from same admin session in quick succession
- POST requests to /admin/delete_room.php without Referer header or with external origins
Network Indicators:
- Unusual traffic patterns where admin endpoints receive requests from non-admin IPs
- HTTP requests with suspicious Referer headers pointing to external domains
