Description

The FTP Backup on the ADM will not properly strictly enforce TLS certificate verification while connecting to an FTP server using FTPES/FTPS. An improper validated TLS/SSL certificates allows a remote attacker can intercept network traffic to perform a Man-in-the-Middle (MitM) attack, which may intercept, modify, or obtain sensitive information such as authentication credentials and backup data. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.ROF1 as well as from ADM 5.0.0 through ADM 5.1.2.RE51.
