Descriptions

A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to read arbitrary files on the underlying filesystem of the device. The vulnerability is due to insufficient file scope limiting. An attacker could exploit this vulnerability by creating a specific file reference on the filesystem and then accessing it through the web-based management interface. A successful exploit could allow the attacker to read arbitrary files from the filesystem of the underlying operating system.
