CVE-2021-33923

Local disclosure via insecure file permissions

Published Sep 29, 2021 · Updated Aug 4, 2024

Incorrect default permissions in Confluent Ansible (cp-ansible) 5.5.0, 5.5.1, 5.5.2 and 6.0.0 allow local attackers to access private keys and a state database. Default installations assign overly permissive permissions to sensitive local configuration files, exposing their contents to rogue operating-system users. Exploitation requires local account access; the documented consequence is information disclosure and possible compromise of key material, without reported integrity or availability impact.
