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 was determined in hcr707305003 shiroiAdmin 1.1/1.3. Affected is the function FileController::upload of the file app/common/controller/FileController.php. Executing a manipulation of the argument File can lead to unrestricted upload. The attack may be launched remotely. The exploit has been publicly disclosed and may be utilized. Upgrading to version 1.4 is able to address this issue. This patch is called 3ecde28ea8a20a3840dbfefd6d6863ee79a83e70. It is suggested to upgrade the affected component. The vendor was contacted early about this disclosure but did not respond in any way.

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-284

The application fails to correctly restrict what a user can do or reach, so functions or resources are available to people who should not have them. Attackers simply probe for the paths where the check is missing or wrong. The fix is to enforce access-control decisions consistently on every request, evaluated against the acting user rather than assumed from context.

Recommended fix High confidence

version 1.4

  1. Create a complete backup of the current application files and database before proceeding with any changes
  2. Download shiroiAdmin version 1.4 from the official repository at github.com/hcr707305003/shiroiAdmin
  3. Replace the existing application files with the new version 1.4 files, ensuring the FileController.php (app/common/controller/FileController.php) is updated with the patched version
  4. If using git, you can alternatively run 'git pull' or checkout to the fixed version tag
  5. Review any new configuration files or database migrations that may be required for version 1.4
  6. Restart the web server or PHP-FPM service to ensure the new code is loaded
  7. Test the file upload functionality to verify the vulnerability has been remediated
