Restrict Access
linuxLimit network access to TeamPass to only trusted IP addresses or internal networks
iptables -A INPUT -p tcp --dport 80 -s trusted_ip -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s trusted_ip -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
Web Application Firewall
allDeploy a WAF with code injection protection rules
🧯 If You Can't Patch
- Implement strict network segmentation to isolate TeamPass from other critical systems
- Enable detailed logging and monitoring for suspicious activities and implement alerting
🔍 How to Verify
Check if Vulnerable:
Check the TeamPass version in the application interface or by examining the source code files. Versions below 3.0.9 are vulnerable.Check Version:
Check the version in the TeamPass web interface under Settings or examine includes/config.phpVerify Fix Applied:
Verify the version is 3.0.9 or higher and check that the commit 1f51482a0c4d152ca876844212b0f8f3cb9387af is present in the installation.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to TeamPass endpoints
