Leak some secret configuration variables. Difficulty: Medium. UnicornBox stores some configuration variables in a config.yml file in a folder separate from the users’ files: The layout of the server storage is as follows: site/ files/ foo1.txt foo2.txt ... config/ config.yml. Your task: Gain access to the secrets stored within config.yml. The backend for this project exclusively uses single quotes for SQL queries. It is possible to select constants in SQL rather than selecting column names. For example, SELECT 1, 'foo', 'evan' will return a single row with 3 columns, with values of 1, 'foo' and 'evan'.$ ssh -t [email protected] \~cs161/proj1/start Replace XXXwith the last three letters of your instructional account, and YYwith the number of a hive machine (1-20).
