CVE-2025-63225 — Eurolab-Srl Elts 100 Firmware security vulnerability
The Eurolab ELTS100_UBX device (firmware version ELTS100v1.UBX) is vulnerable to Broken Access Control due to missing authentication on critical administrative endpoints. Attackers can directly access and modify sensitive system and network configurations, upload firmware, and execute unauthorized actions without any form of authentication. This vulnerability allows remote attackers to fully compromise the device, control its functionality, and disrupt its operation.

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.
