CISCO DEVICES RUNNING VSTACK ASR1001X FULL
For a full list see the ios_facts module documentation page. Hello, I have a strange problem with what appears to be vstack/tftp related. For example: ansible_net_model returns the model, and ansible_net_image returns the image file the device is running. Let’s use the ios_facts module which returns key-value pairs for use in subsequent tasks. CVE-2018-0171 affects the IOS and IOS-XE network operating systems and Ansible can obtain this information easily.
CISCO DEVICES RUNNING VSTACK ASR1001X INSTALL
Cisco devices that are congured as a Smart Install Director are not affected by these attacks. To mitigate a CVE, the networking platform and specific version of code is required. obtain and change the startup-cong le and force a reload of the device, load a new IOS image on the device, and execute high-privilege CLI commands on switches running Cisco IOS and IOS XE Software. One of the first things a CVE requires is collection of inventory. Users leverage Ansible modules to access devices, retrieve information, execute commands and handle systems using specific keywords. “.a vulnerability in the Smart Install feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition, or to execute arbitrary code on an affected device.” In this blog post we are going to walk through CVE-2018-0171 which is titled “Cisco IOS and IOS XE Software Smart Install Remote Code Execution Vulnerability.” This CVE is labeled as critical by Cisco, with the following headline summary: While Red Hat does not report or keep track of individual networking vendors CVEs, Red Hat Ansible Engine can be used to quickly automate mitigation of CVEs based on instructions from networking vendors. In below scenario, the command using PIPE will provide output of interfaces which are down. In Cisco’s March 2018 Semiannual Cisco IOS and IOS XE Software Security Advisory Bundled Publication, 22 vulnerabilities were detailed. We will use above options under PIPE to have more understanding on their usage. Since the majority of network operations is still manual, the need to mitigate quickly and reliably across multiple platforms consisting of hundreds of network devices becomes extremely important. Many IT organizations do not have a comprehensive strategy for mitigating security vulnerabilities that span multiple teams (networking, servers, storage, etc.).

Just like with Windows and Linux servers, networking devices can be exploited by vulnerabilities found in their operating systems.
