CVE-2024-45493 — An issue was discovered in MSA FieldServer Gateway 5.0.0 through 6.5.2 (Fixed in 7.0.0)

Critical CVSS 9.8

An issue was discovered in MSA FieldServer Gateway 5.0.0 through 6.5.2 (Fixed in 7.0.0). The FieldServer Gateway has internal users, whose access is supposed to be restricted to login locally on the device. However, an attacker can bypass the check for this, which might allow them to authenticate with an internal user account from the network (if they know their password).

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.
