IRIX 6.5: GEN004010 (in versions v1 r1 through v1 r0.98)

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 possibly leading to system and network compromise.

Check Content

Check the permissions of the /usr/etc/traceroute file. # ls -D /usr/etc/traceroute If the file has an extended ACL, this is a finding.

Fix Text

Remove the extended ACL from the file. # chmod A- /usr/etc/traceroute
