CVE-2018-20091: An SQL injection vulnerability was found in Cloudera Data Science Workbench (CDSW) 1.4.0 through 1.4.2.

An SQL injection vulnerability was found in Cloudera Data Science Workbench (CDSW) 1.4.0 through 1.4.2. This would allow any authenticated user to run arbitrary queries against CDSW's internal database. The database contains user contact information, encrypted CDSW passwords (in the case of local authentication), API keys, and stored Kerberos keytabs.

Security readout for executives and security teams

Plain-English summary

CVE-2018-20091 is an authenticated SQL injection in Cloudera Data Science Workbench 1.4.0 through 1.4.2. A logged-in user could query the product's internal database, potentially exposing contact information, encrypted local passwords, API keys, and stored Kerberos keytabs.

Executive priority

Treat this as a high-priority credential exposure risk for affected CDSW environments. It is not KEV-listed in the provided data, but the potential impact includes access to API keys and Kerberos keytabs.

Technical view

The CVE describes SQL injection reachable by any authenticated CDSW user, allowing arbitrary queries against the CDSW internal database. Published CVE data does not include CVSS, CWE, exploit details, or a named fixed version in the provided bundle.

Likely exposure

Exposure appears limited to organizations running Cloudera Data Science Workbench versions 1.4.0, 1.4.1, or 1.4.2, especially where many users have CDSW accounts or local authentication, API keys, or Kerberos keytabs are stored.

Exploitation context

The provided sources do not show known active exploitation, and CISA KEV status is false. Risk remains significant because exploitation requires only authenticated access and the described database contents include sensitive credentials and authentication material.

Researcher notes

The source bundle is specific about affected versions and database impact but incomplete on scoring, root-cause details, exploitability nuances, and remediation. Avoid assuming unauthenticated exposure or public exploit availability without additional vendor or threat-intelligence evidence.

Mitigation direction

  • Identify whether CDSW 1.4.0 through 1.4.2 is deployed.
  • Check Cloudera security bulletins and support guidance for fixed versions or workarounds.
  • Restrict CDSW access to trusted users until remediation is complete.
  • Review and rotate exposed API keys or Kerberos keytabs if compromise is suspected.
  • Review CDSW authentication and database access logs for unusual authenticated activity.

Validation and detection

  • Inventory CDSW deployments and record exact product versions.
  • Confirm whether local authentication, API keys, or Kerberos keytabs are used.
  • Check whether affected versions are internet-accessible or broadly reachable internally.
  • Review vendor advisories for remediation status and apply the documented fix.
  • After remediation, verify affected versions are no longer running.
