CVE-2024-21589 — Juniper Paragon Active Assurance Control Center security vulnerability

High CVSS 7.5

An Improper Access Control vulnerability in the Juniper Networks Paragon Active Assurance Control Center allows an unauthenticated network-based attacker to access reports without authenticating, potentially containing sensitive configuration information. A feature was introduced in version 3.1.0 of the Paragon Active Assurance Control Center which allows users to selectively share account data. By exploiting this vulnerability, it is possible to access reports without being logged in, resulting in the opportunity for malicious exfiltration of user data. Note that the Paragon Active Assurance Control Center SaaS offering is not affected by this issue. This issue affects Juniper Networks Paragon Active Assurance versions 3.1.0, 3.2.0, 3.2.2, 3.3.0, 3.3.1, 3.4.0.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

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

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
