Technical description

A Use of Default Password vulnerability in the 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. A change of this password is not enforced during the provisioning of the software, which can make full access to the system by unauthorized actors possible.This issue affects all versions of vLWC before 3.0.94.

——6In Ciena's Navigator Network Control Suite (NCS) and Manage Control Plan (MCP), there are hidden system accounts used for internal software operations. Some of these accounts have default passwords that may be predictable. While these accounts have very limited permissions on their own, an attacker could combine an attack using one of these accounts with other potential weaknesses to launch a more significant attack, possibly leading to escalation of privilege on the system.3d
