CVE-2019-16003: Cisco UCS Director Information Disclosure Vulnerability

A vulnerability in the web-based management interface of Cisco UCS Director could allow an unauthenticated, remote attacker to download system log files from an affected device. The vulnerability is due to an issue in the authentication logic of the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request to the web interface. A successful exploit could allow the attacker to download log files if they were previously generated by an administrator.

Security readout for executives and security teams

Plain-English summary

CVE-2019-16003 is an information disclosure issue in Cisco UCS Director's web management interface. A remote unauthenticated attacker could obtain system log files, but only if an administrator had previously generated those logs. The known impact is limited confidentiality exposure, not system takeover or service disruption.

Executive priority

Handle as a targeted confidentiality risk. Prioritize internet-exposed or broadly reachable UCS Director systems, especially where logs may contain sensitive infrastructure details. It is not presented as a critical takeover issue, but exposed management logs can still aid follow-on attacks.

Technical view

The flaw is an authentication logic weakness in Cisco UCS Director web UI, mapped to CWE-306. The CVSS 3.0 score is 4.3 with network attack vector and no privileges required. Successful exploitation allows downloading previously generated system log files; affected versions are not specified in the bundle.

Likely exposure

Organizations running Cisco UCS Director with its web-based management interface reachable from untrusted networks have the main exposure. Risk depends on whether administrator-generated system logs exist and what sensitive operational details those logs contain.

Exploitation context

The bundle does not show CISA KEV listing or cited evidence of active exploitation. The described attack is remote and unauthenticated, but the impact is limited to log file disclosure under the stated condition that logs were previously generated by an administrator.

Researcher notes

Evidence is limited to the CVE record and Cisco advisory reference in the bundle. The product versions and fixed releases are not included here, so validation should anchor on Cisco's advisory. Avoid assuming broader Cisco UCS products are affected.

Mitigation direction

  • Review Cisco's advisory for affected and fixed release guidance.
  • Restrict UCS Director management access to trusted administrative networks.
  • Audit whether administrator-generated log files are present on affected systems.
  • Treat exposed logs as potentially sensitive operational data.
  • Monitor vendor guidance for any updated remediation details.

Validation and detection

  • Inventory Cisco UCS Director deployments and management interface exposure.
  • Confirm product versions against Cisco's advisory.
  • Check whether system log files were previously generated by administrators.
  • Review access logs for unusual web interface requests.
  • Assess disclosed logs for credentials, tokens, or internal topology details.
