A vulnerability in an API of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against users of the application web-based interface. This vulnerability exists because the API does not properly validate user-supplied input. An attacker could exploit this vulnerability by sending malicious input to the API. A successful exploit could allow the attacker to execute arbitrary script code in the context of the web-based interface or access sensitive, browser-based information. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link:https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-vmanage-xss-eN75jxtW
