Technical details
The vulnerability is an OS command injection flaw (CWE-78) combined with improper privilege management (CWE-269) in an internal cluster management function. An attacker with code execution on one node in a clustered Kiteworks deployment can supply malicious input that reaches a privileged execution context due to insufficient input validation, allowing arbitrary OS command execution with elevated privileges on peer cluster nodes. The attack vector is local and requires low privilege access to a cluster member; the function is not reachable from outside the cluster.
