Junos OS and Junos OS Evolved: An Unchecked Return Value in multiple users interfaces affects confidentiality and integrity of device operations

Summary

An Unchecked Return Value vulnerability in the user interfaces to the Juniper Networks Junos OS and Junos OS Evolved, the CLI, the XML API, the XML Management Protocol, the NETCONF Management Protocol, the gNMI interfaces, and the J-Web User Interfaces causes unintended effects such as demotion or elevation of privileges associated with an operators actions to occur. Multiple scenarios may occur; for example: privilege escalation over the device or another account, access to files that should not otherwise be accessible, files not being accessible where they should be accessible, code expected to run as non-root may run as root, and so forth.
