                   March 8th, 2006

---

Another credentials leak was found in Netcool/NeuSecure Security Information
Management platform which leads to remote backend database access
with administrative privileges by an unauthenticated remote user

Problems :

• Web interface Applet parameters have credentials stored in clear
  which allows access to backend database.
• Version information leak.

Procedure:

Web client mozilla 1.5.0.1
Navigate to company;s Neusecure Server Website:

View source :

<SCRIPT LANGUAGE="JAVASCRIPT">
var ap_width = '';
var ap_height = '';
var paramNameArray = ["ARCHIVE", "CODEBASE", "CODE", "EVENT_LIMIT", "FiresScriptEvents", "MAYSCRIPT", " database.CMS_DBTYPE", "database.CMS_DBNAME", "database.CMSM_DBNAME", "database.CMS_DBHOST", "database.CMS_DBUSER", "database.CMS_DBPASS", "agent_count_limit", " triton.ticket.export", "username", "sessionid", "javaplugin.jre.params", "database.java.connectionURL"];
var paramValueArray = ["JavaClasses.jar", ".", " Triton.TritonApplet.class", "", "true", "true", "mysql", "nsdbp", "nsdbm", "localhost", "ns", " password", "2000", "", "", "fb9ad3ab8968e88e4a576f598b39d6

browser.constructApplet('TritonApplet', paramNameArray, paramValueArray, ap_width, ap_height);
</SCRIPT>

Outcome:

• Default settings for database user [ns] allows connection from any host.
• These credentials are used to connect to NeuSecure backend Mysql database with the following privileges:

Alter Tables To alter the table
Create temporary tables Databases To use CREATE TEMPORARY TABLE
Create Databases,Tables,Indexes To create new databases and tables
Delete Tables To delete existing rows
Drop Databases,Tables To drop databases and tables
File File access on server To read and write files on the server
Grant option Databases,Tables To give to other users those privileges you possess
Index Tables To create or drop indexes
Insert Tables To insert data into tables
Lock tables Databases To use LOCK TABLES (together with SELECT privilege)
Process Server Admin To view the plain text of currently executing queries
References Databases,Tables To have references on tables
Reload Server Admin To reload or refresh tables, logs and privileges
Replication client Server Admin To ask where the slave or master servers are
Replication slave Server Admin To read binary log events from the master
Select Tables To retrieve rows from table
Show databases Server Admin To see all databases with SHOW DATABASES
Shutdown Server Admin To shutdown the server
Super Server Admin To use KILL thread, SET GLOBAL, CHANGE MASTER, etc.
Update Tables To update existing rows
Usage Server Admin No privileges - allow connect only

• Also, under Mozilla client applet renders to provide a Help button which gives out the version
  of the NeuSecure product and it's service pack version.
  So far IE6 does not display applet in a way to glean this information.

Workaround:
One can change access permissions for user ns in the database
to include only valid hosts to prevent direct backend logins.

Conclusion:

• Vendor needs to validate user session before accessing the applet.
• Vendor should not store credential cleartext.

Vendor communication:

Attempt to make the vendor aware of this problem was ignored.
