Check: GEN004000

IRIX 6.5: GEN004000 (in versions v1 r1 through v1 r0.98)

Title

The traceroute file must have mode 0700 or less permissive. (Cat II impact)

Discussion

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 that may lead to system and network compromise.

Check Content

# ls -lL /usr/etc/traceroute If the traceroute command has a mode more permissive than 0700, this is a finding.

Fix Text

Change the mode of the traceroute command. # chmod 0700 /usr/etc/traceroute
