FreeBSD : mysql -- GRANT access restriction problem (01c231cd-4393-11d9-8bb9-00065be4b5b6)
Medium Nessus Plugin ID 18817
The remote FreeBSD host is missing one or more security-related updates.
When a user is granted access to a database with a name containing an underscore and the underscore is not escaped then that user might also be able to access other, similarly named, databases on the affected system. The problem is that the underscore is seen as a wildcard by MySQL and therefore it is possible that an admin might accidentally GRANT a user access to multiple databases.
