Security Bulletin TYPO3-20051114-7: fileadmin/_temp_/
Component Type: Core
Affected Components: File Editor in Install Tool
Versions: TYPO3 3.8.0 and earlier
Vulnerability Type: Information Disclosure
Severity: High
Problem Description:
Situations are imaginable where sensitive information gets stored in the fileadmin/_temp_/ directory. If misconfigured in your web server, this directory can be browsable and therefore expose that information.
Solution:
Generally, please make sure to configure your web server to not allow directory indexing (or limit it to directories where you really want it).
Furthermore, we recommend to create a .htaccess file in fileadmin/_temp_/ that contains the lines
Order deny,allow
Deny from all
From TYPO3 3.8.1 on, full installation packages ("Dummy", "Quickstart" etc.) contain this .htaccess file by default.
