Trivial File Transfer Protocol (TFTP) is a simple file transfer protocol,
typically used to automatically transfer configuration or boot files between systems.
TFTP does not support authentication and can be easily hacked. The package
tftp
is a client program that allows for connections to a tftp
server.
It is recommended that TFTP be removed, unless there is a specific need for TFTP (such as a boot server). In that case, use extreme caution when configuring the services.
The following script can be run on the host to remediate the issue.
#!/bin/bash
# CAUTION: This remediation script will remove tftp
# from the system, and may remove any packages
# that depend on tftp. Execute this
# remediation AFTER testing on a non-production
# system!
if rpm -q --quiet "tftp" ; then
yum remove -y "tftp"
fi
The following playbook can be run with Ansible to remediate the issue.
