Summary
A Use of Default Password vulnerability in Juniper Networks Support Insights (JSI) Virtual Lightweight Collector (vLWC) allows an unauthenticated, network-based attacker to take full control of the device. vLWC software images ship with an initial password for a high privileged account, and a change of this password is not enforced during provisioning. This issue affects all versions of vLWC before 3.0.94.
Risk Assessment
The organization is at risk of complete device takeover by an unauthorized network attacker, potentially leading to data breaches, integrity loss, and further compromise of the infrastructure.
Recommendation
Immediately upgrade vLWC software to version 3.0.94 or later and enforce changing the default password for the privileged account during initial setup.
