Description

A vulnerability in the web management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to conduct directory traversal attacks and obtain read and write access to sensitive files on a targeted system. The vulnerability is due to a lack of proper validation of files that are uploaded to an affected device.
