CVE-2021-29667: IBM Spectrum Scale 5.0.0 through 5.0.5.6 and 5.1.0 through 5.1.0.2 is potentially vulnerable to CSV Injection.

IBM Spectrum Scale 5.0.0 through 5.0.5.6 and 5.1.0 through 5.1.0.2 is potentially vulnerable to CSV Injection. A remote attacker could execute arbitrary commands on the system, caused by improper validation of csv file contents. IBM X-Force ID: 199403.

Security readout for executives and security teams

Plain-English summary

IBM Spectrum Scale versions 5.0.0 through 5.0.5.6 and 5.1.0 through 5.1.0.2 can mishandle CSV content. If an attacker gets malicious CSV content processed and a user interaction occurs, commands could run on a system. This is high risk, but public evidence here does not show active exploitation.

Executive priority

Treat as a high-priority product remediation item for affected Spectrum Scale environments. It is not currently evidenced as actively exploited, but the potential impact includes command execution and loss of confidentiality, integrity, and availability.

Technical view

The issue is CSV injection from improper validation of CSV file contents in IBM Spectrum Scale. The CVSS 3.0 score is 7.0 with high confidentiality, integrity, and availability impact, high attack complexity, no privileges required, and user interaction required. The source bundle does not provide detailed trigger conditions or exploit mechanics.

Likely exposure

Exposure is limited to organizations running the listed IBM Spectrum Scale 5.0.x or 5.1.0.x versions. Risk depends on whether CSV content can be influenced by an attacker and later handled in a way that triggers the injection condition.

Exploitation context

CISA KEV status is false, and the CVSS exploit maturity is unproven. The bundle supports potential arbitrary command execution but does not cite public exploitation, exploit availability, or confirmed in-the-wild activity.

Researcher notes

The public bundle is sparse. The CVSS vector indicates local attack vector and user interaction, while the description mentions a remote attacker. Validate exposure through product versioning and data-flow review rather than assuming internet-reachable exploitability.

Mitigation direction

  • Inventory IBM Spectrum Scale versions across all clusters and management hosts.
  • Check IBM advisory guidance for the supported fix or upgrade path.
  • Prioritize remediation for systems processing CSV content from external or semi-trusted sources.
  • Restrict who can submit, import, or influence CSV content until remediated.
  • Avoid opening untrusted CSV outputs in formula-capable spreadsheet tools.

Validation and detection

  • Confirm whether any deployed version falls within 5.0.0-5.0.5.6 or 5.1.0-5.1.0.2.
  • Map workflows where Spectrum Scale creates, imports, exports, or displays CSV content.
  • Verify remediation status against IBM’s advisory and installed package versions.
  • Review administrative procedures for handling CSV files from untrusted sources.
  • Document compensating controls if vendor remediation cannot be applied immediately.
