Name of the Vulnerable Software and Affected Versions Cisco DNA Center Software (affected versions not specified)

Description A vulnerability in the web-based management interface could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack, manipulating an authenticated user into executing malicious actions without their awareness or consent. The issue is due to insufficient CSRF protections. An attacker could exploit this by persuading a user to follow a specially crafted link, potentially allowing them to perform arbitrary actions on the device, including modifying the device configuration, disconnecting the user's session, and executing Command Runner commands.
