CVE-2021-29892: IBM Cognos Controller information disclosure

IBM Cognos Controller 11.0.0 and 11.0.1 could allow a remote attacker to obtain sensitive information, caused by the failure to properly enable HTTP Strict Transport Security. An attacker could exploit this vulnerability to obtain sensitive information using man in the middle techniques.

Security readout for executives and security teams

Plain-English summary

IBM Cognos Controller 11.0.0 and 11.0.1 may fail to enforce HTTP Strict Transport Security, increasing the chance that sensitive information could be exposed if an attacker can intercept traffic.

Executive priority

Treat as a moderate confidentiality risk. It is not reported as actively exploited, but financial or governance data in Cognos Controller may justify timely validation and remediation.

Technical view

The issue is CWE-319, cleartext transmission exposure, from improper HSTS enablement. CVSS 3.1 is 5.9 with network attack vector, high attack complexity, no privileges, no user interaction, and high confidentiality impact only.

Likely exposure

Exposure appears limited to IBM Cognos Controller versions 11.0.0 and 11.0.1. Systems are most relevant if reachable over networks where interception or downgrade risks exist.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. Exploitation is described as requiring man-in-the-middle techniques, which raises attack complexity.

Researcher notes

Evidence identifies affected versions, weakness class, CVSS vector, and MITM-based impact. The provided bundle does not include a specific patched version or confirmed workaround.

Mitigation direction

  • Review IBM advisory for vendor-supported fixes or configuration guidance.
  • Prioritize affected internet-facing or partner-accessible Cognos Controller deployments.
  • Ensure Cognos Controller access is HTTPS-only where vendor-supported.
  • Validate HSTS enforcement through approved configuration or front-end controls.
  • Reduce exposure on untrusted networks until vendor guidance is applied.

Validation and detection

  • Inventory IBM Cognos Controller versions across production and disaster recovery.
  • Confirm whether any deployment runs version 11.0.0 or 11.0.1.
  • Check HTTPS responses for expected HSTS enforcement.
  • Review proxy, load balancer, and application TLS termination points.
  • Document network paths where traffic interception risk is plausible.
