Level 6 Username : natas6 Password : aGoY4q2Dc6MgDq4oL4YtoKtyAg9PeHa1 URL : http://natas6.natas.labs.overthewire.org
To solve this level, we first log into the natas6 application using the credentials provided above.
We can see that the application provides a text box to enter a secret. Presumably, if the secret matches what the application expects, we should get our password for the next round.
Looking at the source code, we can see that the application checks the entered value against a secret obtained from the file ‘ includes/secret.inc ‘. Therefore, if we can find out what that value is, we might be able to obtain the password for the next level.
Upon navigating to http://natas6.natas.labs.overthewire.org/includes/secret.inc, we can see that the application shows the password for the next level in a comment. We can now use that secret in the application and Voila!, the application prints the password for the next level.
