CVE-2024-2321 — Wso2 Api Manager security vulnerability

Medium CVSS 5.6

An incorrect authorization vulnerability exists in multiple WSO2 products, allowing protected APIs to be accessed directly using a refresh token instead of the expected access token. Due to improper authorization checks and token mapping, session cookies are not required for API access, potentially enabling unauthorized operations. Exploitation requires an attacker to obtain a valid refresh token of an admin user. Since refresh tokens generally have a longer expiration time, this could lead to prolonged unauthorized access to API resources, impacting data confidentiality and integrity.

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.
