[原文]The "Upload new image" command in the "Manage Images" eFiction 1.1, when members are allowed to upload images, allows remote attackers to execute arbitrary PHP code by uploading a filename with a .php extension that contains a GIF header, which passes the image validity check but executes any PHP code within the file.


[CNNVD]eFiction多个远程输入验证漏洞(CNNVD-200512-212)

        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。

21124
eFiction Image Upload Arbitrary Command Execution
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Public

- 漏洞描述

eFiction contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue occurs because the image upload functionality does not validate file extensions for user-supplied files. If an authenticated user uploads an executable file, it may be possible to execute arbitrary PHP code resulting in a loss of integrity.
