CVE-2018-10916 (opens in a new tab)How to fix?
Upgrade RHEL:7 lftp to version 0:4.4.8-12.el7 or higher.
This issue was patched in RHSA-2020:1045.
NVD Description
Note: Versions mentioned in the description apply only to the upstream lftp package and not the lftp package as distributed by RHEL.
See How to fix? for RHEL: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.
