CVE-2026-12943: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in IBM HMC V10.3.1050.0
IBM HMC V10.3.1050.0 through 10.3.1064.0 and IBM HMC V11.1.1110.0 through 11.1.1112.0 Management systems in IBM Power environments (HMC and Novalink) could allow an unauthenticated user to execute arbitrary commands with elevated privileges on the system due to improper validation of user supplied input.
AI Analysis
Technical Summary
CVE-2026-12943 is an OS command injection vulnerability (CWE-78) affecting IBM Hardware Management Console (HMC) versions 10.3.1050.0 through 10.3.1064.0 and 11.1.1110.0 through 11.1.1112.0. The vulnerability arises from improper neutralization of special elements in user input, enabling an unauthenticated attacker to execute arbitrary commands with elevated privileges on the system. This impacts IBM Power environment management systems including HMC and Novalink. The vulnerability is publicly known and assigned a critical severity with a CVSS 3.1 base score of 9.8, indicating high impact on confidentiality, integrity, and availability.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to execute arbitrary OS commands with elevated privileges on affected IBM HMC systems. This can lead to full system compromise, including unauthorized access, data manipulation, and disruption of management operations in IBM Power environments.
Mitigation Recommendations
Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. No official fix or temporary workaround is documented in the provided data. Organizations using affected versions should monitor IBM advisories closely and apply patches or mitigations as soon as they become available.
