CVE-2025-5088

Arista CloudVision Exchange (CVX) Cluster Privilege Escalation via MCS Redis Session

State: Published
Severity: 8.7 High
Published: Jun 5, 2026
Updated: Jun 9, 2026
Reserved: May 22, 2025

Description

An authenticated Redis session could be used to obtain full root access to all servers in the CVX cluster. Note that this would require an attacker to have both network access to the Redis service on a CVX server and the Redis password. Please note that all Redis communication, including authentication, occurs over plaintext in the present day. TLS support is tracked under RFE1294850.
