This vulnerability (CVE-2025-5088) involves improper privilege management (CWE-269) in Arista Networks EOS / CloudVision eXchange (CVX). An attacker with authenticated access to the Redis service on a CVX server can leverage this to gain root access across the CVX cluster. The Redis service transmits data and authentication credentials in plaintext, which may facilitate credential interception. The affected product versions include 4.30.0 through 4.34.0F. The CVSS v3.1 base score is 8.3, indicating high severity with network attack vector, low attack complexity, required privileges of low, no user interaction, and high impact on confidentiality and integrity, with low impact on availability. No vendor advisory or patch information is currently provided.

Successful exploitation grants an attacker full root access to all servers in the CVX cluster, compromising confidentiality and integrity of the system. The plaintext transmission of Redis authentication credentials increases the risk of credential interception. The vulnerability requires network access to the Redis service and knowledge of the Redis password, which limits exposure to attackers with some level of access.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict network access to the Redis service on CVX servers and protect Redis passwords to mitigate risk. Monitor for updates from Arista Networks regarding TLS support for Redis communication and official patches.
