Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-94

The application evaluates attacker-influenced input as code, handing them a way to run logic inside the process. Depending on the runtime this can escalate directly to remote code execution. Remediation means removing dynamic evaluation of untrusted input and replacing it with safe, data-driven alternatives.

Recommended fix High confidence

Fujitsu Software Linux openFT version 12.1D00 or later / Fujitsu Software Oracle Solaris openFT version 12.1D00 or later

  1. Identify the Fujitsu openFT installation on the system (Linux or Oracle Solaris) using package manager or filesystem inspection
  2. Backup current openFT configuration files and data according to Fujitsu backup procedures
  3. Upgrade Fujitsu Software Linux openFT to version 12.1D00 or later, or Fujitsu Software Oracle Solaris openFT to version 12.1D00 or later, using Fujitsu's official upgrade documentation
  4. Verify the upgrade was successful by checking the installed version matches or exceeds 12.1D00
  5. Restart openFT services as specified in Fujitsu post-upgrade documentation
  6. Validate that openFT functionality is working correctly
