The TFTP daemon must operate in "secure mode" which provides access only to a single directory on the host file system.


Overview

Finding ID Version Rule ID IA Controls Severity
V-847 GEN005080 SV-37560r1_rule ECSC-1 High
Description
Secure mode limits TFTP requests to a specific directory. If TFTP is not running in secure mode, it may be able to write to any file or directory and may seriously impair system integrity, confidentiality, and availability.
