Technical description
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.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
