Vulnerability discussion

Devices can find their startup configuration either in their own NVRAM or access it over the network via TFTP or Remote Copy (rcp). Loading the image from the network is taking a security risk since the image could be intercepted by an attacker who could corrupt the image resulting in a denial of service. Configuration auto-loading can be enabled when the device is connected to a non-operational network. Once the device is connected to an operational (i.e. production) network, configuration auto-loading must be disabled.

Check content

Review the device configuration to determine if the configuration auto-loading feature is disabled. If the configuration auto-loading feature is enabled when the device is connected to an operational network, this is a finding.

Fix text

Disable the configuration auto-loading feature, when connected to an operational network.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
