Admidio relies on adm_my_files/.htaccess to deny direct HTTP access to uploaded documents. The Docker image ships with AllowOverride None in the Apache configuration, which causes Apache to silently ignore all .htaccess files. As a result, any file uploaded to the
documents module regardless of the role-based permissions configured in the UI, is directly accessible over HTTP without authentication by anyone who knows the file path. The file path is disclosed in the upload response JSON.
File 1: Intended protection (ignored):
adm_my_files/.htaccess
Require all denied
File 2: Apache config that neutralizes it:
docker exec admidio-sec-app cat /etc/apache2/apache2.conf/etc/apache2/apache2.conf (Docker image)
<Directory ${APACHE_DOCUMENT_ROOT}>
AllowOverride None
</Directory>
AllowOverride None instructs Apache to skip .htaccess processing entirely, the deny rule never executes. The upload directory is inside the web root at /opt/app-root/src/adm_my_files/ and returns HTTP 200 for direct requests.
File 3: Upload response leaks the direct URL: system/file_upload.php, upload response JSON:
{
"files": [{
"name": "sensitive_poc.txt",
"url": "http://TARGET/adm_my_files/documents_research/TEST-SENSITIVE/sensitive_poc.txt"
}]
}
Step 1: Admin creates a restricted folder (visible only to Administrator role):
<img width="1161" height="784" alt="imagen" src="https://github.com/user-attachments/assets/25d81e44-9a7c-4991-b72e-6e664d176695" />
modules/documents-files.php→ permissions set to roleAdministratoronly.
Step 2: Admin uploads a file to the restricted folder.
<img width="1239" height="294" alt="imagen" src="https://github.com/user-attachments/assets/84c1bcd1-47d7-4115-ac0f-653b0a6d7301" /> <img width="1051" height="150" alt="imagen" src="https://github.com/user-attachments/assets/1ed7fab7-59cb-4d5b-8c60-12108490d1e4" />Bạn đang dùng một trong các sản phẩm này?

http://TARGET/adm_my_files/documents_research/TEST-SENSITIVE/sensitive_poc.txt
Step 3: Unauthenticated request retrieves the file:
curl -X GET 'http://TARGET/adm_my_files/documents_research/TEST-SENSITIVE/sensitive_poc.txt'
# Response: full file contents — no authentication required
Step 4: Confirm folder is role-restricted:
SELECT fil_name, fol_name, fol_public FROM adm_files JOIN adm_folders ON fil_fol_id = fol_id
ORDER BY fil_id DESC LIMIT 5; -- fol_public = 0, role restricted — yet file is publicly accessible
Option 1 (preferred): Enable AllowOverride in Apache config:
<Directory /opt/app-root/src/adm_my_files>
AllowOverride All
</Directory>
Option 2: Move uploads outside the web root:
Store uploaded files in a directory outside DOCUMENT_ROOT and serve them exclusively through Admidio's download handler (modules/documents-files.php?mode=download), which enforces role checks before serving the file.
Option 3: Apache-level explicit deny (does not require .htaccess):
<Directory /opt/app-root/src/adm_my_files>
Require all denied
</Directory>
The most robust long-term fix is Option 2 — moving uploads outside the web root eliminates the dependency on Apache configuration correctness entirely.
