CVE-2019-1626: Cisco sd-wan firmware permissions and access controls vulnerability

Cisco · Sd Wan Firmware

A vulnerability in the vManage web-based UI (Web UI) of the Cisco SD-WAN Solution could allow an authenticated, remote attacker to gain elevated privileges on an affected vManage device. The vulnerability is due to a failure to properly authorize certain user actions in the device configuration. An attacker could exploit this vulnerability by logging in to the vManage Web UI and sending crafted HTTP requests to vManage. A successful exploit could allow attackers to gain elevated privileges and make changes to the configuration that they would not normally be authorized to make.
