CVE-2017-20040

Credential disclosure via plaintext password storage

Published Jun 11, 2022 · Updated Apr 15, 2025

Cleartext password storage in SICUNET Access Controller 0.32-05z allows local users to read account credentials from device storage. The password-storage component preserves user passwords in plaintext instead of applying a one-way password hash. The published material does not identify a file or database table, and local access to stored data is required to recover the credentials.
