📦 What is this software?
Teedy by Sismics
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where attacker gains administrative access, modifies user accounts, accesses sensitive documents, and potentially deploys backdoors.
Likely Case
Account takeover leading to unauthorized access to sensitive documents, data exfiltration, and privilege escalation within the Teedy instance.
If Mitigated
Limited impact with proper CSRF protections, though some administrative functions might still be vulnerable if other controls fail.
🎯 Exploit Status
Exploitation requires tricking an authenticated admin user to visit a malicious page. Proof-of-concept code is available in public repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after 1.11 (check latest release)
Vendor Advisory: https://github.com/sismics/docs/releases
Restart Required: No
Instructions:
1. Check current Teedy version. 2. Update to latest version after 1.11. 3. Verify CSRF protections are enabled. 4. Test administrative functions.
🔧 Temporary Workarounds
Enable CSRF Protection
allEnsure CSRF tokens are properly implemented and validated for all POST requests
Check Teedy configuration for CSRF settings
Verify anti-CSRF middleware is active
Restrict Admin Access
allLimit administrative access to specific IP ranges and require MFA for admin accounts
Configure firewall rules for admin interface
Enable MFA in Teedy settings
🧯 If You Can't Patch
- Implement WAF rules to block suspicious POST requests to /api/user/admin
- Isolate Teedy instance behind reverse proxy with CSRF protection
🔍 How to Verify
Check if Vulnerable:
Check if Teedy version is 1.11 or earlier. Test by attempting CSRF attack against /api/user/admin endpoint.
Check Version:
Check Teedy web interface settings or examine application files for version information
Verify Fix Applied:
Verify version is updated beyond 1.11. Test that POST requests to /api/user/admin require valid CSRF tokens.
