Technical details

A privilege escalation or improper access control vulnerability exists in Arista CloudVision Portal (CVP) versions prior to 2016.1.2.1. The flaw is located within the management plane and is specifically related to how the system handles requests to the '/web/system/console/bundle' endpoint. A remote attacker with valid low-privileged credentials can send a crafted request to this endpoint to bypass intended access restrictions. Successful exploitation allows the attacker to interact with internal configuration mechanisms, potentially leading to a complete compromise of the CVP instance. The issue is addressed in version 2016.1.2.1 and later.
