CVE-2023-0451Network attack vector

Unauthenticated file disclosure via passwordless READONLY access

Published Jan 26, 2023 · Updated Jan 16, 2025

Improper access control in Econolite EOS before 3.2.23 allows remote attackers to read log, database, and configuration files. The READONLY access path serves these files without requiring a password, including a configuration file containing usernames and MD5 credential hashes. Network access to the controller is sufficient, and the disclosed records cover administrator and technician accounts.
