CVE-2023-1269
📋 TL;DR
CVE-2023-1269 involves hard-coded credentials in the easyappointments scheduling software, allowing attackers to gain unauthorized access to the application. This affects all installations using versions prior to 1.5.0, potentially compromising appointment data and system integrity.
💻 Affected Systems
- easyappointments
📦 What is this software?
Easyappointments by Easyappointments
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to access, modify, or delete all appointment data, inject malicious code, or pivot to other systems.
Likely Case
Unauthorized access to sensitive appointment information, customer data exposure, and potential data manipulation.
If Mitigated
Limited impact with proper network segmentation and access controls, though credentials remain exposed in code.
🎯 Exploit Status
Exploitation requires only knowledge of the hard-coded credentials, which are publicly documented in the fix commit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.5.0
Vendor Advisory: https://github.com/alextselegidis/easyappointments/commit/2731d2f17c5140c562426b857e9f5d63da5c4593
Restart Required: No
Instructions:
1. Backup your current installation and database. 2. Download version 1.5.0 or later from GitHub. 3. Replace all files except config.php and uploads directory. 4. Run database update if needed. 5. Verify functionality.
🔧 Temporary Workarounds
Manual Credential Removal
allManually remove hard-coded credentials from source code files
grep -r 'hardcoded_password' /path/to/easyappointments/
Edit identified files to remove hard-coded credentials
Access Restriction
linuxRestrict network access to the application using firewall rules
iptables -A INPUT -p tcp --dport 80 -s trusted_network -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the application
- Monitor authentication logs for unauthorized access attempts using the known credentials
🔍 How to Verify
Check if Vulnerable:
Check if version is below 1.5.0 by examining the application's version file or checking for hard-coded credentials in source code.Check Version:
grep -r "define('APP_VERSION'" /path/to/easyappointments/ || cat /path/to/easyappointments/application/config/constants.php | grep APP_VERSIONVerify Fix Applied:
Verify version is 1.5.0 or higher and that hard-coded credentials are no longer present in the codebase.📡 Detection & Monitoring
Log Indicators:
- Failed login attempts followed by successful authentication with default credentials
- Unusual access patterns from unexpected IP addresses
Network Indicators:
- Authentication requests using known hard-coded credentials
- Traffic to admin interfaces from unauthorized sources
SIEM Query:
