When you encounter SA injection points, you can execute commands, but the web and database are separated, what do you do? When the database is not connected to the Internet by the server, I just want to do it from the web. This article is reprinted from t00ls. I hope to provide some penetration ideas for database web separation by injecting sa permissions to everyone.SA point, system permission, executable command, web and db separation.

Finally, the encrypted result is calculated with the user's ewh. after the ciphertext in the DB file is compared, the "password entered is inconsistent with the password of the last successful logon. $ 0a is verified on the server
