CVE-2023-44182

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.

Workarounds

There are no known workarounds for this issue.

Methods that may reduce, but not eliminate, the risk of exploitation of these problems, and which do not mitigate or resolve the underlying problems include:

• Discontinuing the use of any unnecessary administrative interfaces to the system

• Using access lists or firewall filters to limit access to the device only from trusted users, hosts, and networks

• Limiting the number of changes performed to a device through administrative interfaces

• Reducing the frequency of unique telemetry events
