Title
The traceroute file must not have an extended ACL. (Cat II impact)
Discussion
If an extended ACL exists on the traceroute executable file, it may provide unauthorized users with access to the file. 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.
Check Content
Open a terminal session and enter the following command to view the "/usr/sbin/traceroute" file extended ACLs. ls -lL /usr/sbin/traceroute If the permissions include a '+', the file has an extended ACL, this is a finding.
Fix Text
Open a terminal session and enter the following command to remove the extended ACLs. chmod -N /usr/sbin/traceroute
