CVE-2025-57438 — The 2wcom IP-4c 2.15.5 device suffers from a Broken Access Control vulnerability

Medium CVSS 6.8

The 2wcom IP-4c 2.15.5 device suffers from a Broken Access Control vulnerability. Certain sensitive endpoints are intended to be accessible only after the admin explicitly grants access to a manager-level account. However, a manager-level user can bypass these controls by intercepting and modifying requests.

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.
