CVE-2024-50377

Configuration tampering via static backup archive password

Published Nov 26, 2024 · Updated Nov 26, 2024

Hard-coded credentials in Advantech EKI-6333 backup handling allow local users to forge encrypted configuration archives. The backup function encrypts archives with a static default password, allowing the secret to be reused to build a malicious archive. High privileges and a user-assisted restore are required before the crafted configuration can alter the access point.
