MPSB 04-05 Potential Risk in Dreamweaver Remote Database
Originally posted: April 1, 2004
Last updated: April 1, 2004
Dreamweaver's remote database connectivity for testing
dynamic database-driven websites installs scripts that
may reveal DSNs to outside attackers. A sophisticated
attacker may also be able to use these scripts to send
SQL commands to the server and gain control of the
Customers should not define a database connection using
the driver on a testing server accessible to the public.
To prevent unauthorized access to the database, password-
protect the database. If a database connection has been
defined, use Dreamweaver's Remove Connection Scripts
menu command to remove the files that expose the database.
This issue is described in greater detail in Security
implications of remote database connectivity (TechNote
Macromedia categorizes this issue as a critical update
and recommends affected users immediately remove the
connection scripts from publicly accessible servers.
Affected Software Versions:
Dreamweaver MX 2004 (all versions)
Dreamweaver MX (all versions)
Dreamweaver UltraDev 4 (all versions)
When you specify "Using Driver On Testing Server" or
"Using DSN on Testing Server" in the database connections
dialog box, Dreamweaver automatically uploads a script
file to the testing server that allows Dreamweaver to
manipulate the remote database driver via the HTTP
protocol. This allows Dreamweaver to get the database
information it needs in order to help the user create
their site. However, this file does make it possible to
see the data source names (DSNs) defined on the system.
If the DSNs and databases are not password protected,
the script also enables an attacker to issue SQL commands
to the database.
Macromedia would like to thank David Litchfield of Next
Generation Security Software Limited for reporting this
vulnerability and for working with us to help protect
our customers' security.
