Description
A vulnerability in the web UI of Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, could allow an unauthenticated, remote attacker to read arbitrary files that are stored in an affected system. The attacker does not need to have valid user credentials. This vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing an XML file. An attacker could exploit this vulnerability by sending a crafted request to an affected system. A successful exploit could allow the attacker to read arbitrary files that are stored in the affected system.
