Technical details
The set_hostname_internal function in cluster_internal_api passes the hostname parameter directly to a shell command without sanitization, allowing OS command injection (CWE-78). An authenticated attacker with administrative privileges can craft a malicious hostname containing shell metacharacters to execute arbitrary commands on the host system. The attack requires network access and high privileges, but results in full command execution capability under the NooBaa process context.
