CVE-2024-0264
📋 TL;DR
This vulnerability allows remote attackers to bypass authentication in SourceCodester Clinic Queuing System 1.0 by manipulating the formToken argument in /LoginRegistration.php. It affects all users running this software version, potentially enabling unauthorized access to the system. The exploit is publicly available, increasing the risk of attacks.
💻 Affected Systems
- SourceCodester Clinic Queuing System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full administrative access, leading to data theft, system compromise, or further exploitation like remote code execution.
Likely Case
Unauthorized users bypass login to access sensitive patient queuing data or administrative functions.
If Mitigated
If proper network segmentation and access controls are in place, impact may be limited to isolated systems with minimal data exposure.
🎯 Exploit Status
Exploit scripts are publicly available on GitHub, making it easy for attackers to automate attacks without authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch is available; consider upgrading if a newer version is released or apply workarounds.
🔧 Temporary Workarounds
Restrict access to /LoginRegistration.php
allBlock or limit access to the vulnerable file using web server rules or network controls.
# Example for Apache: RewriteRule ^/LoginRegistration\.php$ - [F]
# Example for Nginx: location ~ /LoginRegistration\.php$ { deny all; }
Implement strong authentication checks
allAdd server-side validation for formToken to prevent manipulation, such as using secure tokens or session validation.
# Modify PHP code to validate tokens, e.g., if($_POST['formToken'] !== $_SESSION['validToken']) { die('Access denied'); }
🧯 If You Can't Patch
- Isolate the system on a segmented network to limit exposure and prevent lateral movement.
- Monitor logs for unauthorized access attempts to /LoginRegistration.php and implement intrusion detection.
🔍 How to Verify
Check if Vulnerable:
Check if the file /LoginRegistration.php exists and contains code handling formToken without proper validation; test with exploit scripts from public repositories.Check Version:
# Check software version in source code or documentation; for example, grep for version in files or check admin panel.Verify Fix Applied:
After applying workarounds, attempt to exploit the vulnerability using public PoC scripts; successful access should be denied.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /LoginRegistration.php with manipulated formToken parameters
- Failed login attempts followed by successful unauthorized access
Network Indicators:
- Traffic patterns showing exploitation attempts from external IPs to the vulnerable endpoint
SIEM Query:
Example: source="web_logs" AND url="/LoginRegistration.php" AND (formToken != expected_value OR status=200 after failed auth)🔗 References
