MariaDB and MySQL Authentication Bypass Exploit

JohnBert writes "A security bug in MariaDB and MySQL has been revealed, allowing a known username and password to access the master user table of a MySQL server and dump it into a locally-stored file. By using a tool like John the Ripper, this file can be easily cracked to reveal text passwords that can provide further access. By committing a threaded brute-force module that abuses the authentication bypass flaw to automatically dump the password database, you can access the database using the cracked password hashes even if the authentication bypass vulnerability is fixed."
