JSI Virtual Lightweight Collector: Shell escape allows privilege escalation to root
A Permissive List of Allowed Input vulnerability in the CLI of Juniper Networks Support Insights (JSI) Virtual Lightweight Collector (vLWC) allows a local, high privileged attacker to escalate their privileges to root.
The CLI menu accepts input without carefully validating it, which allows for shell command injection. These shell commands are executed with root permissions and can be used to gain complete control of the system.
This issue affects all JSI vLWC versions before 3.0.94.
