Assume I have dumped MySQL user list using
SELECT user, host, password, ssl_type FROM mysql.user;
The result looks like this:
+------------------+-----------+-------------------------------------------+----------+
| user | host | password | ssl_type |
+------------------+-----------+-------------------------------------------+----------+
| admin | % | *blablablablablablablablablablablablablaa | ANY |
+------------------+-----------+-------------------------------------------+----------+
Should this information be considered sensitive? Can an attacker use the password information to access the MySQL database? It seems the password is hashed, therefore it is not directly usable, but perhaps it can be still exploited somehow, e.g. to help creating rainbow tables for my server, or something like this?
