CVE:CVE-2006-4893
CNNVD:CNNVD-200609-323
phpBB XS是一款基于PHP的论坛程序
phpBB XS在处理用户请求时存在输入验证漏洞，远程攻击者可能利用此漏洞在服务器上以Web进程权限执行任意命令。
phpBB XS的bb_usage_stats/includes/bb_usage_stats.php脚本没有正确验证phpbb_root_path参数的输入数据，允许攻击者通过包含本地或外部资源的任意文件导致执行任意代码。成功攻击要求打开了register_globals。bb_usage_stats.php中漏洞代码如下： 
line 24 include($phpbb_root_path . 'bb_usage_stats/includes/bb_usage_stats_constants.' . $phpEx); 
line 25 include($phpbb_root_path . 'bb_usage_stats/language/lang_' . $board_config['default_lang'] . '/bb_usage_stats_lang.' . $phpEx); 
line 26 include($phpbb_root_path . 'bb_usage_stats/includes/bb_usage_stats_functions.' . $phpEx);
solution:Upgrade phpbb_xs phpbb_xs to a higher version than 0.58,and avoid the version (,0.58]
