CVE-2024-33471Network attack vector

SMTP credential disclosure via retained mail settings

Published May 24, 2024 · Updated Feb 13, 2025

Credential exposure in AVTECH Room Alert 4E 4.4.0 and earlier allows remote authenticated users to obtain stored SMTP credentials. The firmware retains configured SMTP credentials when an administrator changes the mail server host, then sends them in plaintext while authenticating to the replacement server. Administrative access to the web settings and an existing SMTP configuration are required, exposing the reused mail credentials.
