medium Nessus Plugin ID 138619

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

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. (CVE-2018-10916)

Solution

Run 'yum update lftp' to update your system.
