Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
IBM Big SQL on IBM Cloud Pak for Data 7.1.0, 7.1.1, 7.2.0, and 7.2.3 could allow an authenticated user with appropriate permissions to obtain sensitive information by bypassing data masking rules using a CREATE TABLE SELECT statement. IBM X-Force ID: 220480.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

IBM Big SQL on Cloud Pak for Data contains a vulnerability where authenticated users with appropriate permissions can bypass data masking rules by using a CREATE TABLE SELECT (CTAS) statement, allowing unauthorized access to sensitive information that should be masked.

MitigationUpgrade IBM Cloud Pak for Data to a patched version beyond 7.2.3. Review user permissions and data masking policies to ensure proper segregation of sensitive data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed IBM Big SQL version
    Use the Big SQL command line interface (bsql) or query the system catalog: SELECT * FROM SYSCAT.SOFTWAREVERSION or check the Cloud Pak for Data version via the cpd-cli tool: cpd-cli manage version
    Affected if The installed version matches 7.1.0, 7.1.1, 7.2.0 through 7.2.3, or is exactly 7.2.3
  2. Verify data masking rules are defined
    Query the data masking metadata: SELECT * FROM SYSCAT.DATAMASKS or check the Cloud Pak for Data security policies for any defined masking rules on sensitive tables
    Affected if Data masking rules exist and are defined for tables containing sensitive data
  3. Check if CREATE TABLE SELECT (CTAS) is permitted for users with access to masked data
    Review user permissions and roles in Big SQL: SELECT GRANTEE, TABNAME, PRIVILEGETYPE FROM SYSCAT.TABAUTH WHERE GRANTEE = '<user>' and examine if users with SELECT access can execute CTAS statements
    Affected if Users with SELECT permission on masked tables can also execute CREATE TABLE AS SELECT statements
  4. Test CTAS bypass of masking
    As an authenticated user with data access, run: CREATE TABLE new_table AS SELECT * FROM masked_table, then query the new table to see if unmasked data is accessible
    Affected if The CTAS operation returns unmasked/sensitive data that should have been masked

You are affected if IBM Big SQL version 7.1.0, 7.1.1, 7.2.0-7.2.3 is running, data masking rules are defined, and authenticated users can execute CTAS statements that expose unmasked sensitive data.

Upgrade available Upgrade to a release after 7.2.3
Interim mitigation

Upgrade IBM Cloud Pak for Data to a patched version beyond 7.2.3. Review user permissions and data masking policies to ensure proper segregation of sensitive data.

Recommended fix Moderate confidence

Upgrade to Big SQL on Cloud Pak for Data 7.3.0 or later (or the latest available fix pack beyond 7.2.3)

  1. Contact IBM support or visit the official IBM support portal to obtain the fixed version for Big SQL on Cloud Pak for Data.
  2. Upgrade IBM Big SQL on Cloud Pak for Data to a version newer than 7.2.3 (e.g., 7.3.0 or later).
  3. After upgrading, verify that data masking rules are properly enforced by testing CREATE TABLE SELECT statements with masked columns.
  4. Review user permissions and ensure only authorized users have access to sensitive data.
