Network Isolation
allRestrict access to TeamPass to trusted IP addresses only
# Example for Apache: Require ip 192.168.1.0/24
# Example for Nginx: allow 192.168.1.0/24; deny all;
Web Application Firewall Rules
allImplement WAF rules to block code injection patterns
# ModSecurity rule example: SecRule ARGS "@rx (eval|system|exec|passthru|shell_exec)" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Implement strict network access controls to limit TeamPass access to authorized users only
- Enable detailed logging and monitoring for suspicious activities in TeamPass access logs
🔍 How to Verify
Check if Vulnerable:
Check your TeamPass version by viewing the footer in the web interface or checking the includes/config.php file for version information.Check Version:
grep -i "version" includes/config.php 2>/dev/null || echo "Check web interface footer for version"Verify Fix Applied:
Verify version is 3.0.10 or higher in the web interface footer or config.php. Test that the specific vulnerable functionality has been patched.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to TeamPass endpoints
- Suspicious PHP function calls in web server logs
- Multiple failed login attempts followed by successful access
Network Indicators:
- Unexpected outbound connections from TeamPass server
- Unusual traffic patterns to TeamPass web interface
