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
Fess is a deployable Enterprise Search Server. Prior to version 14.19.2, the createTempFile() method in org.codelibs.fess.helper.SystemHelper creates temporary files without explicitly setting restrictive permissions. This could lead to potential information disclosure, allowing unauthorized local users to access sensitive data contained in these files. This issue primarily affects environments where Fess is deployed in a shared or multi-user context. Typical single-user or isolated deployments have minimal or negligible practical impact. This issue has been patched in version 14.19.2. A workaround for this issue involves ensuring local access to the environment running Fess is restricted to trusted users only.

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.

dbcve analysis
How this class of weakness works · CWE-732

A sensitive file, directory, or resource is created with permissions more open than it needs, so unintended users can read or modify it. Attackers look for exactly these loose defaults. Remediation is assigning the minimum permissions required and verifying them at install time and at runtime.

Recommended fix High confidence

Fess version 14.19.2

  1. 1. Back up the current Fess installation, including all configuration files, data directories, and custom settings.
  2. 2. Download Fess version 14.19.2 from the official GitHub releases page (github.com/codelibs/fess/releases) or the official Fess download location.
  3. 3. Stop the running Fess service to ensure no active file operations during the upgrade.
  4. 4. Replace the existing Fess installation files with the new version 14.19.2 files.
  5. 5. Restore the configuration and data from the backup created in step 1.
  6. 6. Start the Fess service and verify it runs correctly.
  7. 7. Verify that the createTempFile() method now sets restrictive permissions by reviewing the patched code at github.com/codelibs/fess/commit/25b2009fea2a0f6ccd5aa8154aa54b536c08f6c4 or by testing in a controlled environment.
