Dojo #1Can you recover the admin password ?

Last Update: 2/26/2025, 10:46 AM

Exploration### Spelunking the internals Now that you are able to recover any data, try to explore the database. There is an hidden table containing a flag, can you find where it is ? #### Goal: recover the flag from the hidden table.

Last Update: 2/26/2025, 10:42 AM

Filter bypass### Some filter away from SQL injection Here your input is heavily transformed before being injected into the query. While this make the exploitation more difficult, this shouldn't stop you. #### Goal: recover the admin password

Last Update: 2/26/2025, 10:41 AM

First exfiltration### Time to recover some data Bypassing a password check is nice, but being able to read arbitrary data is better. Try to get the admin password. #### Goal: recover the admin password

Last Update: 2/26/2025, 10:40 AM

Simple Login Bypass### The most Basic SQL injection ever Try to find a way to login as the admin. #### Goal: `is_valid_password = 1`

Last Update: 2/26/2025, 10:39 AM

No LIMIT### Limiting the query This query should give us the any password, but the limit 0 prevent it. Can you bypass it ? #### Goal: recover the admin password

Later we had a contact with the Hacker responsible for the breach so we asked him how he had been able to pull this password He replied: "NO COMMENTS, NO PROBLEMS" Will you be 197 enough to build a working injection to recover the admin password from the users table? ### Goal: - Get the password of the user named `admin` - Single Query (not blind)

Dojo #16# Blind SQL Injection hardstuck in the LIMIT statment - DOJO #16 (Until 01/04/2022) Submit your solution [HERE](https://yeswehack.com/programs/dojo) for a chance to win an exclusive swag pack! :D ## Description This code runs a SQL statment where it collects some data from the table `users` with a `LIMIT` statment that is controlled by user input. *What can go wrong* ?! :) ... Most of the time when your able to inject a value inside the `LIMIT` statment. The backend code checks if the user input is an (int) type. Ex: `(int) LIMIT = $nr`. This makes it a lot harder to exploit. Does this code really filter the user input to (int) type values? ;) ## Hint * Space is almost never needed when you got a keyboard full of special chars anyway. You will be suprised how much you can do with the "*limitation*" your facing. *Be creative, your a hacker, aren't you?* Use this when you stuck!

(*"ERROR": "SqliteError: unrecognized token: \"x'$passwd'\"" is **not** a challenge error*) --- ## Story time [DOJO #19...](https://dojo-yeswehack.com/practice/f79d5c5050e2) Developer Jeff returned to the office on Monday after a long weekend of partying and beer. He still has a hangover, but he was strong and managed to secure the SQL statement (*The database only leaked 62 times*.) From now on, Jeff doesn't trust user input and limited the administrator access to **one** employee only.
