IBM Cloud Pak for Security (CP4S) 1.7.0.0, 1.7.1.0, 1.7.2.0, and 1.8.0.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 207320.

Security readout for executives and security teams

Plain-English summary

IBM Cloud Pak for Security versions 1.7.0.0 through 1.8.0.0 used weaker cryptography than expected. If an attacker can meet the high-complexity conditions, highly sensitive information could be decrypted. The business impact is confidentiality loss, not service disruption or data modification, based on the published scoring.

Executive priority

Treat as a planned but important remediation item for affected CP4S environments. It does not have confirmed active exploitation in the provided sources, but it concerns possible decryption of highly sensitive information.

Technical view

CVE-2021-29894 affects IBM CP4S 1.7.0.0, 1.7.1.0, 1.7.2.0, and 1.8.0.0. The CVSS 3.0 vector is network reachable, unauthenticated, high attack complexity, no user interaction, with high confidentiality impact only. IBM X-Force tracks it as ID 207320.

Likely exposure

Exposure is likely limited to organizations running the listed IBM Cloud Pak for Security versions. The source bundle does not identify affected components, default exposure, deployment prerequisites, or specific cryptographic algorithms.

Exploitation context

The CVE is not listed as CISA KEV in the source bundle. The CVSS vector includes exploit maturity as unproven and attack complexity as high, so active exploitation should not be assumed from these sources.

Researcher notes

The public bundle lacks algorithm details, affected modules, proof-of-concept status, and exact fixed versions. Validation should focus on version evidence, vendor advisory review, and whether sensitive data is processed or stored by affected deployments.

Mitigation direction

  • Check IBM advisory 6493729 for the official fixed level or interim guidance.
  • Upgrade or remediate affected CP4S versions according to IBM support instructions.
  • Prioritize systems handling sensitive security telemetry or investigation data.
  • If vendor guidance is unclear, open an IBM support case before accepting risk.

Validation and detection

  • Inventory CP4S deployments and record exact installed versions.
  • Confirm whether any deployment is 1.7.0.0, 1.7.1.0, 1.7.2.0, or 1.8.0.0.
  • Review IBM X-Force ID 207320 and advisory 6493729 for current remediation status.
  • Document compensating controls and residual confidentiality risk until remediation is complete.
