8.1 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
Summary
A vulnerability in the web UI of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to gain read and write access to information that is stored on an affected system. The vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by persuading a user to import a crafted XML file with malicious entries. A successful exploit could allow the attacker to read and write files within the affected application.
