CVE-2026-14275

IBM i Access Client Solutions (ACS) is Affected By Multiple Vulnerabilities

Published Sep 14, 2026 CVSS 3.1 · 6.3 Medium EPSS < 1% KEV · Not listed

Description

IBM i Access Family 1.1.2.0 through 1.1.9.15 IBM i Access Client Solutions could allow an authenticated user to execute arbitrary commands with normal user privileges on the system due to improper validation of user supplied input in a STRPCCMD CL command.

Analysis

Technical impact

IBM i Access Client Solutions versions 1.1.2.0 through 1.1.9.15 allow an authenticated user to execute arbitrary commands on the system due to improper validation of user-supplied command. The flaw is a classic command injection vulnerability (CWE‑78) that permits a user to run any command that their account is permitted to execute on the target machine.

Affected Systems

The vulnerability affects the IBM i Access Family product line. Any installation of IBM i Access Client Solutions with a version number between 1.1.2.0 and 1.1.9.15 inclusive is impacted. Upgrading to version 1.1.9.16 or later resolves the issue.

Risk and Exploitability

The CVSS score of 6.3 categorizes the vulnerability as medium severity. The exploit probability (EPSS) is currently low at < 1%, and the vulnerability is not listed in the CISA KEV catalog. An attacker who can authenticate to the system can supply malicious input to the STRPCCMD command, causing the system to execute arbitrary commands with the privileges of the authenticated user. This can lead to privilege abuse or facilitate further lateral movement or persistence, depending on the user account’s permissions and other system configurations.

Affected Products

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

OpenCVE Recommended Actions

Upgrade IBM i Access Client Solutions to version 1.1.9.16 or later as supplied by IBM.
If immediate upgrade is not possible, restrict the privileges of accounts that have access to the STRPCCMD command to limit the commands they can run.
Enable auditing of CL command usage and monitor for unexpected STRPCCMD invocations to detect potential exploitation.
