CVE-2021-0220 — Juniper Junos Space security vulnerability

Medium CVSS 6.8

The Junos Space Network Management Platform has been found to store shared secrets in a recoverable format that can be exposed through the UI. An attacker who is able to execute arbitrary code in the victim browser (for example via XSS) or access cached contents may be able to obtain a copy of credentials managed by Junos Space. The impact of a successful attack includes, but is not limited to, obtaining access to other servers connected to the Junos Space Management Platform. This issue affects Juniper Networks Junos Space versions prior to 20.3R1.

Matched remediation archetype

Information disclosure and sensitive data exposure

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
  • Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
  • Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

  • Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
  • Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
  • Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
