Command Argument Injection Vulnerability in Cosminexus Component Container

Published Sep 8, 2026 CVSS 3.1 · 9.8 Critical EPSS < 1% KEV · Not listed

Description

Command Argument Injection Vulnerability in Cosminexus Component Container.

This issue affects Cosminexus Component Container: from 11-70-01 before 11-70-03, from 11-60 before 11-60-03, from 11-50 through 11-50-03, from 11-40 through 11-40-03, from 11-30 through 11-30-08, from 11-20 before 11-20-10, from 11-10 through 11-10-11, from 11-00 through 11-00-12, from 09-87 before 09-87-10, from 09-80 through 09-80-04, from 09-70 before 09-70-28, from 09-50 through 09-50-22, and from 09-00 through 09-00-18.

Analysis

Technical impact

A command argument injection flaw in Hitachi Cosminexus Component Container allows an attacker to supply crafted arguments that are directly passed to the operating system shell, enabling execution of arbitrary commands. This weakness, identified as CWE-88, can compromise confidentiality, integrity, and availability by allowing an attacker to run any code with the privileges of the container process. The high CVSS score of 9.8 reflects the criticality of this ability.

Affected Systems

Affected systems are Hitachi Cosminexus Component Container versions ranging from 09-00 through 09-00-18, 09-50 through 09-50-22, 09-70 before 09-70-28, 09-80 through 09-80-04, 09-87 before 09-87-10, 11-00 through 11-00-12, 11-10 through 11-10-11, 11-20 before 11-20-10, 11-30 through 11-30-08, 11-40 through 11-40-03, 11-50 through 11-50-03, 11-60 before 11-60-03, and 11-70-01 before 11-70-03.

Risk and Exploitability

The vulnerability carries a CVSS score of 9.8 and is not listed in the CISA KEV catalog, but the lack of an EPSS value means the current exploitation probability is unknown. The likely attack vector is via network or application interfaces that accept unfiltered command arguments, and an attacker with sufficient network access can exploit the injection to run arbitrary code inside the container environment.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Consult Hitachi’s advisory and apply the latest available patch or upgrade to a version that is not listed as vulnerable (e.g., 11-70-03 or later, 11-60-03 or later, etc.),
Implement strict input validation and sanitization for all command arguments supplied to the Cosminexus Component Container, ensuring that only expected values are allowed; enforce least privilege on the container process to limit potential damage.
Monitor container logs for anomalous command executions and restrict network exposure of the component container to trusted, authenticated sources.
