⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of all stored passwords, credentials, and sensitive data managed by TeamPass, potentially leading to lateral movement and full organizational compromise.
Likely Case
Unauthorized access to subsets of stored credentials and sensitive information, potentially enabling account takeovers and data breaches.
If Mitigated
Limited exposure of non-critical information or no impact if proper network segmentation and access controls are implemented.
🎯 Exploit Status
The vulnerability requires some level of access to the application but does not require authentication to the vulnerable component.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.0.10
Vendor Advisory: https://github.com/nilsteampassnet/teampass/commit/e9f90b746fdde135da3c7fbe4fa22fe2bd32e66b
Restart Required: Yes
Instructions:
1. Backup your TeamPass database and configuration. 2. Download TeamPass 3.0.10 or later from the official repository. 3. Replace existing files with the new version. 4. Run any database migration scripts if provided. 5. Restart your web server.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to TeamPass to only trusted IP addresses or internal networks.
# Example using iptables for Linux: iptables -A INPUT -p tcp --dport 80 -s TRUSTED_IP -j ACCEPT
# Example using Windows Firewall: New-NetFirewallRule -DisplayName "TeamPass Access" -Direction Inbound -Protocol TCP -LocalPort 80 -RemoteAddress TRUSTED_IP -Action Allow
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the TeamPass application.
- Monitor application logs for unusual access patterns or unauthorized information retrieval attempts.
🔍 How to Verify
Check if Vulnerable:
Check your TeamPass version by viewing the application's about page or checking the version file in the installation directory.
Check Version:
grep -r "version" /path/to/teampass/includes/version.php 2>/dev/null || cat /path/to/teampass/includes/version.php
Verify Fix Applied:
Verify that the version is 3.0.10 or higher and test that sensitive information is no longer accessible through unauthorized means.
📡 Detection & Monitoring
Log Indicators:
- Unusual access patterns to sensitive API endpoints
- Requests for information without proper authentication tokens
- Access from unexpected IP addresses to sensitive data endpoints
Network Indicators:
- Unusual traffic patterns to TeamPass API endpoints
- Requests for sensitive data without authentication headers
SIEM Query:
source="teampass.log" AND (uri_path="/api/*" OR uri_path="/sources/*") AND NOT (user_agent="legitimate_client" OR src_ip IN (trusted_ips))
