CVE-2024-33603Network attack vector

Unauthenticated log disclosure via exposed syslog page

Published Oct 30, 2024 · Updated Oct 30, 2024

Information disclosure in LevelOne WBR-6012 R0.40e6 allows remote attackers to read system and login data via the web interface. The unauthenticated syslog2.htm page returns verbose logs containing memory addresses, settings, debug messages, and administrator login IP addresses. Network access alone exposes this data, and disclosed administrator IP addresses can support session hijacking against the router’s IP-based authentication.
