⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise via account creation with administrative privileges, leading to data theft, ransomware deployment, or persistent backdoor access.
Likely Case
Unauthorized account creation allowing attackers to access sensitive documents, escalate privileges, or maintain persistence in the environment.
If Mitigated
Limited impact with proper network segmentation, strong authentication controls, and monitoring detecting unusual account creation.
🎯 Exploit Status
Simple injection payloads can be crafted based on LDAP query syntax. Public proof-of-concept demonstrates account creation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.13 or later
Vendor Advisory: https://github.com/sismics/docs/releases
Restart Required: Yes
Instructions:
1. Backup Teedy data and configuration. 2. Download Teedy version 1.13 or newer. 3. Stop Teedy service. 4. Replace with patched version. 5. Restart Teedy service. 6. Verify LDAP authentication works correctly.
🔧 Temporary Workarounds
Disable LDAP Authentication
allTemporarily disable LDAP authentication and use local authentication only until patching is possible.
Edit Teedy configuration to set 'ldap.enabled=false' or remove LDAP configuration
Network Access Control
linuxRestrict access to Teedy login page to trusted IP addresses only.
iptables -A INPUT -p tcp --dport 8080 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
🧯 If You Can't Patch
- Implement Web Application Firewall (WAF) rules to block LDAP injection patterns in username field
- Enable detailed logging for all authentication attempts and monitor for unusual account creation patterns
🔍 How to Verify
Check if Vulnerable:
Check if Teedy version is between 1.9-1.12 and LDAP authentication is enabled in configuration.Check Version:
Check Teedy web interface admin panel or configuration files for version information.Verify Fix Applied:
Confirm Teedy version is 1.13 or newer and test LDAP authentication with various username inputs.📡 Detection & Monitoring
Log Indicators:
- Unusual LDAP query patterns in authentication logs
- Multiple failed login attempts with special characters in username
- Unexpected account creation events
Network Indicators:
- HTTP POST requests to login endpoint containing LDAP special characters (=, *, (, ), \, /, +, <, >, ;)
SIEM Query:
source="teedy.logs" AND (username=*\28* OR username=*\29* OR username=*\2A* OR username=*\3D*)
