SV-37465r1: The traceroute file must have mode 0700 or less permissive. | Red Hat Enterprise Linux 5 Security Technical Implementation Guide

Assessment Title

Rule Text

The traceroute file must have mode 0700 or less permissive.

Description

Discussion Text

If the mode of the traceroute executable is more permissive than 0700, malicious code could be inserted by an attacker and triggered whenever the traceroute command is executed by authorized users. Additionally, if an unauthorized user is granted executable permissions to the traceroute command, it could be used to gain information about the network topology behind the firewall. This information may allow an attacker to determine trusted routers and other network information potentially leading to system and network compromise.

Remediation

Change the mode of the traceroute command.
# chmod 0700 /bin/traceroute
