No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue. The advisory points out:

Apache Tomcat packages provided by default repositories of RedHat-based distributions (including CentOS, RedHat, OracleLinux, Fedora, etc.) create a tmpfiles.d configuration file with insecure permissions which allow attackers who are able to write files with tomcat user permissions (for example, through a vulnerability in web application hosted on Tomcat) to escalate their privileges from tomcat user to root and fully compromise the target system.

The exploit is available at exploit-db.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k.
