CVE-2023-28078 — Dell OS10 Networking Switches running 10.5.2.x and above contain a vulnerability with zeroMQ when VLT is configured

Critical CVSS 9.1

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.

Matched remediation archetype

Information disclosure and sensitive data exposure

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
  • Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
  • Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

  • Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
  • Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
  • Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
