Enabling the service config setting causes a Cisco router to be vulnerable to the TFTP Server Attack since it will actively try to retrieve a new configuration file from the nearest TFTP server. An attacker can insert a malicious update file in this process to compromise the Cisco router.

The service config setting was disabled by default in the Cisco IOS in version 12.0, but had been enabled by default in the 11.x series of the IOS trains. This feature is often enabled in later versions since organizations don’t always realize the risk of this setting and will leave it enabled as the migrate through multiple IOS upgrades.

The other items listed don’t enable the service config setting.

Many administrators are hesitant to upgrade the IOS on routers based on past experience with the code introducing instability into the network. It is often difficult to completely test an IOS software upgrade in a production environment because the monolithic kernel requires that the IOS be replaced before the device can be tested. Because of these reasons, IOS upgrades to resolve security flaws are often left undone in many organizations.
