Amazon Linux AMI : lftp (ALAS-2020-1383)

medium Nessus Plugin ID 138055

Language:

Synopsis

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

Description

The version of lftp installed on the remote host is prior to 4.4.8-12.30. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1383 advisory.

 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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update lftp' to update your system.
