Summary

• A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software when it is operating in cluster mode could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system.

  This vulnerability is due to insufficient CSRF protections for the web-based management interface on an affected system. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user. These actions could include modifying the system configuration and deleting accounts.

  Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
