Upgrade Centos:7 lftp-scripts to version 0:4.4.8-12.el7 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream lftp-scripts package and not the lftp-scripts package as distributed by Centos.
See How to fix? for Centos:7 relevant fixed versions and status.
It has been discovered that lftp up to and including version 4.8.3 does not properly sanitize remote file names, leading to a loss of integrity on the local system when reverse mirroring is used. A remote attacker may trick a user to use reverse mirroring on an attacker controlled FTP server, resulting in the removal of all files in the current working directory of the victim's system.
