Description

A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to conduct path traversal attacks and obtain write access to sensitive files on an affected system. The vulnerability is due to insufficient validation of HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to write arbitrary files on the affected system.
