CVE-2026-16606: CWE-94 in Fujitsu Linux openFT
A vulnerability in Fujitsu Software Linux openFT and Fujitsu Software Oracle Solaris openFT before version 12.1D00 allows for unauthenticated remote code execution (pre-auth RCE) on GNU/Linux or Oracle Solaris. The Fsas Technologies PSIRT obtained that intelligence internally and covers the CVE beyond its CNA scope under existing agreement with Fujitsu Germany.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-16606) affects Fujitsu Software Linux openFT and Oracle Solaris openFT versions prior to 12.1D00. It involves CWE-94, which is improper control over code generation, leading to unauthenticated remote code execution on affected systems. The vulnerability allows attackers to execute arbitrary code remotely without any user interaction or privileges. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. The Fujitsu PSIRT team has acknowledged the issue, but no official remediation or patch has been published yet.
Potential Impact
Successful exploitation of this vulnerability allows unauthenticated attackers to execute arbitrary code remotely on affected Fujitsu Linux openFT and Oracle Solaris openFT systems. This can lead to full system compromise, including unauthorized access, data manipulation, and service disruption. The critical CVSS score reflects the high potential impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict network access to the affected service and monitor for unusual activity. Follow Fujitsu's security advisories for updates on patches or mitigations.
