SA14348

VERIFY ADVISORY:
http://secunia.com/advisories/14348/

CRITICAL:
Less critical

IMPACT:
Exposure of system information

WHERE:
>From remote

SOFTWARE:
Tarantella Enterprise 3.x
http://secunia.com/product/1692/
Secure Global Desktop 3.x
http://secunia.com/product/4683/
Secure Global Desktop 4.x
http://secunia.com/product/4004/

DESCRIPTION:
A security issue has been reported in Secure Global Desktop
Enterprise Edition and Tarantella Enterprise, which can be exploited
by malicious people to enumerate valid user accounts and disclose
some system information.

The error message returned for failed logins discloses if the user
account exists and if RSA SecurID authentication is in use.

Successful exploitation requires that RSA SecurID is enabled and that
users share the same username.

The following products are reportedly affected:
* Secure Global Desktop Enterprise Edition, version 4.00
* Secure Global Desktop Enterprise Edition, version 3.42
* Tarantella Enterprise 3, version 3.40
* Tarantella Enterprise 3, version 3.30

SOLUTION:
Ensure that no RSA username is mapped to more than one ENS user
object.

The security issue will reportedly be fixed in releases later than
4.00.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Eliot Mansfield.
