Title: Symantec/Axent NetProwler 3.5.x database configuration
Date: 07.04.01
Application: Symantec/Axent NetProwler 3.5.x
Environment: WinNT
Author: Martin O'Neal [martin.oneal@corsaire.com]
Audience: General distribution
-- Scope --
The aim of this document is to clearly define some issues related to
a potentially unsound database configuration within the NetProwler
application environment as provided by Symantec/Axent [1].
-- History --
Vendor notified: 07.04.01
Document released: 09.05.01
-- Overview --
The latest version of the NetProwler intrusion detection product comes
as a three-tiered architecture, consisting of agents, a management
component, and a console. Both configuration and auditing information
is stored within a MySQL database hosted locally on the management tier
of the product. This database is exposed unnecessarily to potential
network scrutiny due to being configured by default to listen to all
local IP addresses.
-- Analysis --
The MySQL database included with the NetProwler product is used to
store both configuration and auditing information on the management tier.
This is accessed via an ODBC connection on the default MySQL port
(TCP/3306).
Because it is possible to connect to the databases remotely, if the
correct access password can be obtained (see Corsaire advisory
010317-001a [2]), it is possible to amend the data contained within them,
or simply delete the databases causing a denial of service in the
management tier.
In theory, using this flaw it is feasible to disable the IDS capabilities
of NetProwler, perform whatever attack is required, and then reconfigure
the host to its prior state.
As a proof of concept, a tool was created that simply deletes the
NetProwler databases causing a denial of service. This was provided to
the vendor, but will not be made freely available..
-- Recommendations --
The MySQL databases do not need to be accessed by remote systems, so the
MySQL engine can be configured to listen to localhost only. To do this,
edit the c:\my.cnf file and add the following line, then restart the host:
[MySQLd]
bind-address=127.0.0.1
