# FOSS Gallery Admin Version <= 1.0 / Remote Arbitrary Upload Vulnerability
# -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
# Program: FOSS Gallery Admin Version
# Version: <= 1.0
# File affected: processFiles.php
# Download: http://sourceforge.net/projects/fossgallery/

#
# Upload images is only allowed to the admin but the process to upload has
# 3 steps (with 3 pages). only the first page check the user permissions.
#
# STEPS:
# uploadForm1.php -> ask for the number of files you wish to upload
# uploadForm2.php -> ask for the files to upload
# processFiles.php -> process the file(s)
#
# Also image format is not validated and you can upload any file.
#
# You can POST directly in the 3th step (processFiles.php):
# - uploadNeed = 1 ... we only need to upload 1 file
# - uploadFile0 = shell.php ... the file to upload
