Vulnerability details
The vulnerability allows a local authenticated attacker to inject and execute arbitrary commands with elevated privileges on the target system.
The weakness exists in the CLI parser due to sufficiently sanitization of command arguments before passing commands to the Linux shell for execution. A local attacker can submit a malicious CLI command, gain access to the underlying Linux shell and execute arbitrary commands with root privileges.
