Unauthenticated information disclosure via path normalization bypass
Published May 5, 2025 · Updated May 6, 2025
Authentication bypass in LianjiaTech kob 1.0.0-SNAPSHOT allows remote attackers to read restricted node information over HTTP. OperationFilter.doFilter tests the undecoded request URI against a static-resource allow rule, then forwards matching paths without authentication; a /static/../ path reaches protected APIs after normalization. No credentials or user interaction are required, and the demonstrated request exposes server-node data without granting write access or service control.
