- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2018-04-18 · Updated: 2024-09-16

## Affected

- Dell EMC ViPR Controller: versions after 3.0.0.38

## Description

Dell EMC ViPR Controller, versions after 3.0.0.38, contain an information exposure vulnerability in the VRRP. VRRP defaults to an insecure configuration in Linux's keepalived component which sends the cluster password in plaintext through multicast. A malicious user, having access to the vCloud subnet where ViPR is deployed, could potentially sniff the password and use it to take over the cluster's virtual IP and cause a denial of service on that ViPR Controller system.
