For a complete list of advisories and links to them, see Cisco Event Response: Semiannual Cisco IOS and IOS XE Software Security Advisory Bundled Publication. This advisory is part of the March 23, 2016, release of the Cisco IOS and IOS XE Software Security Advisory Bundled Publication, which includes six Cisco Security Advisories that describe six vulnerabilities. ![]() This advisory is available at the following link: There are no workarounds that address this vulnerability other than disabling Smart Install functionality on the vulnerable device. A successful exploit could cause a Cisco Catalyst switch to reload, resulting in a DoS condition.Ĭisco has released software updates that address this vulnerability. An attacker could exploit this vulnerability by sending crafted Smart Install packets to TCP port 4786. The vulnerability is due to incorrect handling of image list parameters. In conclusion, the best way to prevent such vulnerabilities is to implement vulnerability management solutions to detect and fix in real-time such threats caused by device software issues.The Smart Install client feature in Cisco IOS and IOS XE Software contains a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. It has been confirmed that devices in India are prone to these attacks so it may be beneficial to know how to deal with these vulnerabilities. If that option isn’t available, the best option would be to restrict access via an access control list for the interface. One basic safety measure is to run the command “no vstack config” on the affected device. These vulnerabilities will persist for a while so it better to know the safety measures. ![]() This can also lead to denial of service conditions. They can gain control and execute random code on the victim’s router. It has been seen that there are quite a few other vulnerabilities that can be exploited to change the configuration of the router and attack it with malicious code. Though there has been no sign of such crimes yet, it may be wise to be aware of such attacks in case there is a crisis in the future. The vulnerable data may lead up to many more cyber crimes like intellectual property theft, identity theft etc. Therefore the data in the data centres may be in jeopardy. This vulnerability has given access to the inner system infrastructures to the hackers. The web subscribers’ internet connections were cut off due to this flaw in the routers. As a result, this attack affected internet service providers and data centres. The targeted devices were reset and they became unavailable for configuration. ![]() This allows hackers to run arbitrary code on the vulnerable switches, according to a blog by Kaspersky Lab. The attack exploited a vulnerability in software called Cisco Smart Install Client. The attack affected 200,000 router switches all around the world. The data loss and the impact are not completely evident yet. Many countries were affected including Iran, Russia, United States, China, and India. More than 200,000 network switches belonging to the company were hacked. A few days back Cisco faced a massive cyber attack by a group of hackers. Cisco is one of the leading companies in the IT and Networking sector.
