![]() ![]() we would rack and stack 48 at a time this would let us do the hardware (ears) install, test the power supplies, and get the devices ready for initial deployment. Afterward, I have enabled the next access-list: IP access list Infrastructure-ACL-Policy. Single 3560x housed the vstack, ios file, and generalized config file. Review all Cisco switch configuration files for deviations from documented pre-existing configurations. The Smart Install feature was removed in more recent releases, in particular from 16.4.2, 16.5.1b, 16.6.2, 16.7.1, and later. Cisco added this so that if it is enabled, vstack will be present in the running configuration. In the template selector, select iOS as the platform, select App template in the Application section and then click Next. In certain releases of Cisco IOS there is a command available that will disable the Smart Install feature: no vstack. WS-C3750-24TS and doesn't accept the 'no vstack' command.

Hi Colleagues, I have detected in one of my network devices a Cisco Smart vulnerability. However, since the hack apparently resets the targeted devices, making them unavailable, Cisco believes hackers have been merely misusing the Smart Install protocol itself to overwrite the device configuration, instead of exploiting a vulnerability. This vulnerability is documented in Cisco bug ID CSCtt45381 (registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2012-1314. Some researchers believe the attack involves a recently disclosed remote code execution vulnerability ( CVE-2018-0171) in Cisco Smart Install Client that could allow attackers to take full control of the network equipment. Cisco IOS Software contains a DoS vulnerability in the WAAS Express feature that could allow an unauthenticated, remote attacker to cause the router to leak memory or to reload. ![]()
