Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-4371	GEN004000	SV-37465r1_rule	ECLP-1	Medium

Description
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.
