- Severity: CVSS 9.1 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2024-02-15 · Updated: 2024-08-15

## Affected

- Dell Dell SmartFabric OS10: 10.5.5.0, 10.5.5.3, 10.5.5.1 (MX), 10.5.5.2 (MX), 10.5.4.x, 10.5.4.6 (MX), 10.5.3.x, 10.5.2.x

## Description

Dell OS10 Networking Switches running 10.5.2.x and above contain a vulnerability with zeroMQ when VLT is configured. A remote unauthenticated attacker could potentially exploit this vulnerability leading to information disclosure and a possible Denial of Service when a huge number of requests are sent to the switch. This is a high severity vulnerability as it allows an attacker to view sensitive data. Dell recommends customers to upgrade at the earliest opportunity.
