Medium severity, CVSS 6.1. EPSS: 1.7% chance of exploitation in the next 30 days.

A vulnerability in the WebVPN web-based management interface of Cisco Adaptive Security Appliance could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device.
