Aruba Networks Security Advisory

Title: Aruba Mobility Controller TACACS User Authentication and Cross
Site Scripting Vulnerabilities

Aruba Advisory ID: AID-051408
Revision: 1.0

For Public Release on 05/14/2008


+----------------------------------------------------

1.)

TITLE:  Mobility Controller TACACS User Authentication Vulnerability


SUMMARY

A user authentication vulnerability was discovered during standard bug
reporting procedures in the Aruba Mobility Controller.  This
vulnerability only affects customers using TACACS authentication for
Controller management users.

AFFECTED ArubaOS VERSIONS

~ 3.1.1.x, 3.2.0.x, 3.3.1.x and 3.1.1FIPS


DETAILS

Aruba Mobility Controllers may use external authentication methods to
authenticate users. A vulnerability in the TACACS authentication
component may allow unauthorized web UI/ssh/telnet access to the Aruba
Mobility Controller. TACACS is not the default authentication method and
must be configured as an authentication method for users before it will
be used. By default, user accounts and passwords are kept in a local
database which is not vulnerable to this issue.  Other authentication
methods supported by the Aruba Mobility Controller are not vulnerable to
this issue.






IMPACT

An attacker with web UI/ssh/telnet access to the Aruba Mobility
Controller may be able to gain unauthorized access to the administration
account of an Aruba Mobility Controller.


CVSS BASE METRIC SCORE: 10


WORKAROUNDS

Aruba Networks recommends that all customers apply the appropriate
patch(es) as soon
as practical.  However, in the event that a patch cannot immediately be
applied, the
following steps will help to mitigate the risk:

- -  Disable TACACS authentication for all accounts until such time as the
patches can be applied.

- - Do not expose the Mobility Controller administrative interface to
untrusted networks
such as the Internet.


SOLUTION

Aruba Networks recommends that all customers apply the appropriate
patch(es) as soon as practical.  However, in the event that a patch
cannot immediately be applied, the workaround steps will help to
mitigate the risk.

+----------------------------------------------------

2.)

TITLE:  Mobility Controller Web UI Cross Site Scripting Vulnerabilities


SUMMARY

Cross-site scripting vulnerabilities were discovered during standard bug
reporting procedures in the Aruba Mobility Controller. Certain malformed
inputs to the web UI allow the injection of cross-site scripting (XSS)
components, leading to a potential compromise of client web session
integrity.




AFFECTED ArubaOS VERSIONS

~ 2.5.5.x, 2.5.6.x, 2.4.8.x-FIPS, 3.1.1.x, 3.1.1.x-FIPS, 3.2.0.x, 3.3.1.x


DETAILS

Aruba Mobility Controllers may present a web-based management and
captive portal interface.  Providing malformed input to the web UI may
result in the presentation of that input to the user. Malicious XSS
injection via the web UI may not require action to be taken by the victim.


IMPACT

An attacker with web UI access to the Aruba Mobility Controller may be
able to compromise the integrity of a client web session or subvert the
authentication exchange content to retrieve administrator authentication
credentials to the Aruba Mobility Controller.


CVSS BASE METRIC SCORE: 10


WORKAROUNDS

Aruba Networks recommends that all customers apply the appropriate
patch(es) as soon
as practical.  However, in the event that a patch cannot immediately be
applied, the
following steps will help to mitigate the risk:

- - Do not expose the Mobility Controller administrative interface to
untrusted networks
such as the Internet.


SOLUTION

Aruba Networks recommends that all customers apply the appropriate
patch(es) as soon as practical.  However, in the event that a patch
cannot immediately be applied, the workaround steps will help to
mitigate the risk.
