Learn howCisco platforms are achieving infrastructure virtualization.Review themotivation, drivers, and concepts of computing virtualization.They conclude with multiple use cases that show howcontainerization can improve agility and efficiency in a wide range of networkenvironments. Theauthors explore diverse orchestration tools, including LXC, Docker, andKubernetes, and cover both Cisco and open-source tools for building and testingapplications. Youll find modular coverage of configuration, activation,orchestration, operations, and application hosting for each key Cisco softwareplatform: IOS-XE, IOS-XR, and NX-OS. Next, they take a deep dive into containernetworking, introducing Cisco architectural support for containerinfrastructures. First, the authors review essential virtualizationand containerization concepts for all network professionals and introduceleading orchestration tools.

Other advisories with a severity score of 8.6 include denial of service (DoS) vulnerabilities affecting various products running IOS XE, including: Catalyst 9800 Series and Cisco AireOS software for WLC Flexible NetFlow Version 9 Catalyst 9800 Series wireless controllers multicast DNS Cisco 4461 integrated Services Routers cBR-8 Converged Broadband Routers DHCP a IOS XE software IP service-level agreements Software Zone-Based Firewall and the wireless controller software for the Catalyst 9000 Family CAPWAP.A comprehensiveguide to learning container and application hosting capabilities in Ciscoplatforms, and implementing them to achieve higher efficiency in networkdeployments and operationsĬiscoarchitectures offer comprehensive compute virtualization capabilities toaccommodate both native and third-party container hosting, so you cancontainerize and instantiate any application or network service and gainunprecedented value from your networks.ĭirectfrom Cisco, this is the complete guide to deploying and operatingcontainerized application and networkservices on Cisco platforms. However, Cisco notes that "disabling the HTTP Server feature eliminates the attack vector for these vulnerabilities and may be a suitable mitigation until affected devices can be upgraded."

SEE: Mobile security: These seven malicious apps have been downloaded by 2.4m Android and iPhone usersĬVE-2020-3425 is found in the authentication controls of the web management framework, which could allow an attacker to send a crafted API call and a privileged authentication token that gives them administrator privileges on the affected device. An exploit could allow the attacker as a read-only user to execute CLI commands or configuration changes as if they were an administrative user," Cisco notes. "An attacker could exploit this vulnerability by sending a modified HTTP request to the affected device. CVE-2020-3141 is due to a lack of input and validation-checking mechanisms for certain HTTP requests to APIs on an affected device. These are tracked as CVE-2020-3141 and CVE-2020-3425 and can allow an authenticated, remote attacker with read-only privileges to elevate privileges to the level of an administrator user on an affected device.Ĭisco notes attackers don't need to exploit both of the bugs to attack an affected device. The second advisory concerns two privilege escalation vulnerabilities in the web management framework of IOS XE. While there's no workaround Cisco notes that disabling the HTTP Server feature blocks the attack vector for this bug and maybe a suitable mitigation until affected devices are upgraded.

It's due to insufficient authorization of web UI access requests and could allow a user with read-only rights to perform actions with Admin user rights. One, tracked as CVE-2020-3400, is an authorization bypass vulnerability in the Cisco IOS XE software web user interface (UI) that may allow a remote attacker with valid credentials to use part of the UI. There are two advisories with a severity score of 8.8, the highest of this release's 25 high-severity advisories.
