CVE-2023-29256: IBM Db2 information disclosure

IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 10.5, 11.1, and 11.5 is vulnerable to an information disclosure due to improper privilege management when certain federation features are used. IBM X-Force ID: 252046.

Security readout for executives and security teams

Plain-English summary

IBM Db2 can expose sensitive information when certain federation features are used. An attacker needs network access and a low-privileged account, and exploitation is not described as easy. The business risk is data confidentiality, not service disruption or data tampering.

Executive priority

Treat this as a scheduled confidentiality remediation for affected Db2 environments, with higher urgency where sensitive data, broad database access, or exposed network paths exist.

Technical view

CVE-2023-29256 affects IBM Db2 for Linux, UNIX and Windows, including Db2 Connect Server, versions 10.5, 11.1, and 11.5. It is an improper privilege management issue tied to federation features. CVSS 3.1 is 5.3 with high confidentiality impact, high attack complexity, and low privileges required.

Likely exposure

Exposure is most likely in organizations running affected Db2 versions with federation features enabled or available to low-privileged users. Internet-facing Db2 services or broadly reachable internal database networks increase concern.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. The CVSS vector indicates remote network reachability, low privileges required, no user interaction, and high attack complexity.

Researcher notes

Key unknowns remain in the provided bundle: exact vulnerable fix levels, exploit prerequisites beyond the CVSS vector, and named mitigations. Do not assume exploitability without confirming federation configuration and IBM advisory details.

Mitigation direction

  • Review IBM advisory 7010573 for official fix levels and instructions.
  • Apply IBM-recommended updates or fix packs for affected Db2 deployments.
  • Restrict network access to Db2 services to trusted systems only.
  • Review and minimize low-privileged accounts with access to federation features.
  • Check NetApp advisory if Db2 is used through downstream NetApp-supported products.

Validation and detection

  • Inventory Db2 LUW and Db2 Connect Server versions across production and non-production.
  • Identify systems running versions 10.5, 11.1, or 11.5.
  • Confirm whether Db2 federation features are enabled or in use.
  • Compare installed fix levels against IBM advisory guidance.
  • Review database privileges for users able to access federation functionality.
