[原文]PHP remote file include vulnerability in inc/backend_settings.php in Loudblog 0.4 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the $GLOBALS[path] parameter.


[CNNVD]LoudBlog backend_settings.php远程文件包含漏洞(CNNVD-200602-065)

        Loudblog一款PHP实现的基于Web的内容管理系统,以MySQL作为后台数据库,可以方便地发布音频视频内容。
        Loudblog实现上存在输入验证漏洞,远程攻击者可能利用此漏洞在服务器上执行任意命令。Loudblog的backend_settings.php脚本没有充分对用户提交的请求进行过滤,攻击者可以使脚本包含远程服务器上的文件,通过注入脚本代码在服务器上以Web进程权限执行任意命令。

22921
Loudblog backend_settings.php Multiple Parameter Remote File Inclusion
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Public

- 漏洞描述

Loudblog contains a flaw that may allow an attacker to carry out a remote file inclusion attack. The issue is due to the "loudblog/inc/back-end_settings.php" script not properly sanitizing user-supplied input to the 'GLOBALS[path]' or 'language' variables. This may allow a remote attacker to include a file from a remote host that contains arbitrary commands which will be executed by the vulnerable script.
