CVE-2026-14276: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in IBM i Access Family
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 malicious emulator macro RunProgram action.
AI Analysis
Technical Summary
IBM i Access Family versions 1.1.2.0 through 1.1.9.15 contain an OS command injection vulnerability (CWE-78) in the i Access Client Solutions component. This flaw arises from improper neutralization of special elements in user-supplied input within the RunProgram action of an emulator macro. An authenticated user can exploit this to execute arbitrary OS commands with the privileges of the normal user running the application.
Potential Impact
An authenticated attacker can execute arbitrary operating system commands with the privileges of the normal user on the affected system. This can lead to limited confidentiality, integrity, and availability impacts as indicated by the CVSS vector (C:L/I:L/A:L). There is no indication of privilege escalation beyond normal user rights or of exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor IBM's advisories for updates. In the meantime, restrict access to trusted users and avoid running untrusted emulator macros.
