描述：
--------------------------------------------------------------------------------
phpBB是一款使用多种模块扩展的流行的论坛系统。
phpBB viewtopic.php对用户提交的参数缺少充分过滤，远程攻击者可以利用这个漏洞增加任意拥有管理权限的用户帐户。
viewtopic.php对highlight参数缺少充分检查，提交使用多个char()函数的SQL查询，可在系统中增加管理员权限的用户帐户。
另外附件模块对用户提交给"UPLOAD_DIR"字段数据缺少充分过滤，提交包含多个../字符的数据，可绕过WEB ROOT限制，以进程权限查看系统文件内容。
