CVE-2022-3101
📋 TL;DR
This vulnerability in tripleo-ansible allows local attackers to discover sensitive configuration files through brute force directory exploration due to insecure default permissions. It affects OpenStack deployments using vulnerable tripleo-ansible versions, potentially exposing important deployment configuration details.
💻 Affected Systems
- tripleo-ansible
📦 What is this software?
Openstack by Redhat
Openstack by Redhat
Tripleo Ansible by Openstack
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain access to sensitive OpenStack configuration files containing credentials, API keys, or deployment secrets, leading to full infrastructure compromise.
Likely Case
Local users discover configuration files containing deployment details, potentially enabling further attacks or information gathering about the OpenStack environment.
If Mitigated
With proper file permissions and access controls, attackers cannot access sensitive files even if they discover their location.
🎯 Exploit Status
Exploitation requires local access and involves brute force directory traversal to discover sensitive files.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Red Hat advisories for specific patched versions
Vendor Advisory: https://access.redhat.com/security/cve/CVE-2022-3101
Restart Required: No
Instructions:
1. Update tripleo-ansible to patched version from vendor repositories. 2. Verify file permissions on sensitive configuration files. 3. Review and update any custom configurations that may have similar issues.
🔧 Temporary Workarounds
Manual permission hardening
linuxManually set restrictive permissions on sensitive configuration files to prevent unauthorized access
chmod 600 /path/to/sensitive/config/files
chown root:root /path/to/sensitive/config/files
Access control enforcement
linuxImplement strict access controls and monitoring for sensitive directories
setfacl -m u:root:rwx /sensitive/directory
auditctl -w /sensitive/directory -p wa -k sensitive_config
🧯 If You Can't Patch
- Implement strict file system permissions (chmod 600) on all sensitive configuration files
- Use access control lists (ACLs) to restrict directory access and monitor for unauthorized access attempts
🔍 How to Verify
Check if Vulnerable:
Check tripleo-ansible version and review file permissions on configuration files in sensitive directoriesCheck Version:
rpm -q tripleo-ansible # For RHEL-based systemsVerify Fix Applied:
Verify tripleo-ansible is updated to patched version and sensitive files have restrictive permissions (600 or more restrictive)📡 Detection & Monitoring
Log Indicators:
- Failed permission denied errors on sensitive files
- Unusual directory traversal patterns in system logs
- Multiple access attempts to restricted directories
Network Indicators:
- N/A - This is a local file system vulnerability
