Arista Networks CloudVision Portal vulnerabilities

A missing input validation vulnerability in the Fileserver upload API allows an authenticated attacker with file upload privileges to execute stored cross-site scripting (XSS). Successful exploitation could enable the attacker to hijack another CloudVision user's web session, potentially granting full access to their account and administrative permissions.

An authenticated remote attacker with specific permissions can read or write files on the platform filesystem beyond the intended scope through specially crafted requests and/or crafted file uploads to the Network Provisioning Image Repository.

On affected versions of CloudVision Portal (on-premises) or CloudVision Sensor, a path traversal vulnerability exists. An authenticated user with sufficient high privileges could exploit this to extract unintended data from the Sensor.

Insufficient validation in the Single Sign-On (SSO) login flow could allow a remote, unauthenticated attacker to craft a URL that, when clicked by a user, causes the identity provider (IdP) to deliver authentication material to an attacker-controlled URL instead of to CloudVision.
