Network World - Wed, 01/20/2021 - 10:21pm

Cisco has noted and fixed two critical and a number of high-degree vulnerabilities in its SD-WAN software portfolio.

Most of the vulnerabilities could let an authenticated attacker execute command injection attacks against an affected device, which could let the attacker utilize root privileges on the device.

The first critical problem–with a Common Vulnerability Scoring System rating of 9.9 out of 10–is  vulnerability in the web-based management interface of Cisco SD-WAN vManage Software. 

“This vulnerability is due to improper input validation of user-supplied input to the device template configuration,” Cisco stated. “An attacker could exploit this vulnerability by submitting crafted input to the device template configuration. A successful exploit could allow the attacker to gain root-level access to the affected system.”

Wi-Fi Protected Access 3 (WPA3) has brought significant security improvements to Wi-Fi networks, particularly WPA-3Enterprise, which includes tweaks to make authenticating to the network more secure. One of these is has to do with 802.1x authentication that is used to determine whether Wi-Fi clients will be granted access to the enterprise network.

Wi-Fi resources

The enterprise mode of WPA has always allowed you to give each user a unique username/password to login to the Wi-Fi or to utilize unique digital certificates for each user to install on devices for even more security. Now with WPA3-Enterprise, the security is increased as clients are now required to make sure it’s communicating with the real authentication server before sending login credentials. That verification was optional with the earlier two versions of WPA.
