Medium CVSS 5.5

A vulnerability in the logging feature of Cisco NX-OS Software for Cisco Nexus 3000 Series Switches, Cisco Nexus 9000 Series Switches in standalone NX-OS mode, Cisco UCS 6400 Fabric Interconnects, Cisco UCS 6500 Series Fabric Interconnects, and Cisco UCS 9108 100G Fabric Interconnects could allow an authenticated, local attacker access to sensitive information. This vulnerability is due to improper logging of sensitive information. An attacker could exploit this vulnerability by accessing log files on the file system where they are stored. A successful exploit could allow the attacker to access sensitive information, such as stored credentials.

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.
