CVE-2025-2771Network attack vector

Unauthenticated access via missing web interface checks

Published Apr 23, 2025 · Updated Apr 23, 2025

Authentication bypass in BEC Technologies Multiple Routers firmware 1.04.1.512 and 1.04.1.542 allows remote attackers to access functions. The web-based user interface exposes unspecified functionality without first authenticating the requester; ZDI has not disclosed the affected route or handler. No credentials or user interaction are required, and the published assessment limits the demonstrated consequence to unauthorized information access.
