CVE-2025-63525
📋 TL;DR
Blood Bank Management System 1.0 contains an improper access control vulnerability in delete.php that allows authenticated attackers to perform actions with escalated privileges. This affects all installations of Blood Bank Management System 1.0 where attackers have any level of authenticated access.
💻 Affected Systems
- Blood Bank Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise including unauthorized deletion of critical blood bank data, manipulation of blood inventory records, and potential exposure of sensitive donor/patient information.
Likely Case
Unauthorized deletion or modification of blood bank records leading to operational disruption, data integrity issues, and potential regulatory compliance violations.
If Mitigated
Limited impact with proper access controls and monitoring, potentially only affecting non-critical data if segmentation is properly implemented.
🎯 Exploit Status
Exploitation requires authenticated access but minimal technical skill. Public proof-of-concept exists in GitHub repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check for official patch from vendor (none available as of analysis)
2. Consider upgrading to a different blood bank management system
3. Implement workarounds and compensating controls
🔧 Temporary Workarounds
Delete.php Access Restriction
allRestrict access to delete.php file to only authorized administrative users
# Add to .htaccess for Apache:
<Files "delete.php">
Require user admin
</Files>
# For Nginx:
location ~ /delete\.php$ {
allow 192.168.1.0/24;
deny all;
auth_basic "Restricted";
auth_basic_user_file /etc/nginx/.htpasswd;
}
Input Validation Enhancement
allAdd proper authorization checks before processing delete requests
# Add to delete.php before any delete operations:
if (!isset($_SESSION['user_role']) || $_SESSION['user_role'] !== 'admin') {
http_response_code(403);
die('Unauthorized access');
}
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the blood bank system from other networks
- Deploy a web application firewall (WAF) with rules to block unauthorized delete.php requests
🔍 How to Verify
Check if Vulnerable:
Test if non-admin authenticated users can access delete.php functionality or perform delete operations they shouldn't be authorized for.Check Version:
Check application version in admin panel or review source code for version markersVerify Fix Applied:
Verify that only authorized administrative users can successfully access delete.php functionality after implementing controls.📡 Detection & Monitoring
Log Indicators:
- Multiple DELETE requests from non-admin users
- Failed authorization attempts on delete.php
- Unusual delete operations outside normal business hours
Network Indicators:
- HTTP POST requests to delete.php from unauthorized IP addresses
- Unusual patterns of delete operations
SIEM Query:
source="web_logs" AND uri="/delete.php" AND (user_role!="admin" OR user_role IS NULL)
