Advisory # 1:

TITLE

Cross Site Scripting vulnerability in ArubaOS and AirWave
Administration Web Interfaces.

SUMMARY

A persistent Cross Site Scripting vulnerability (XSS) was discovered
where an attacker
could plant an AP with maliciously crafted SSID in the general
vicinity of the wireless LAN
and might be able to trigger a XSS vulnerability in the reporting
sections of the ArubaOS
and AirWave Administration WebUIs.

AFFECTED VERSIONS

    • ArubaOS 3.3.X, 3.4.X, 5.0.X, 6.0.X, 2.4.X-FIPS, 3.3.X-FIPS and
      3.4.X-FIPS
    • AirWave 7.2.X

DETAILS

ArubaOS and AirWave maintain information on all wireless network SSIDs
and APs visible
on the wireless network and the general vicinity. This information is
used for security
and reporting purposes. An attacker could plant an AP with maliciously
crafted SSID and
might trigger a XSS vulnerability in certain sections of the ArubaOS
and AirWave
Administration WebUIs related to reporting.

This vulnerability would manifest when administrator would log in to
the WebUI and
browse to the reporting section. This vulnerability requires the
administrator
to be successfully logged in with valid credentials. However the
malicious AP does
not have to be beaconing the SSID continuously as the SSID information
is stored in the
controller for sometime for reporting purposes after it is first
observed.

IMPACT

An attacker could plant an AP with maliciously crafted SSID in the
general vicinity of the
wireless LAN and might trigger a XSS vulnerability in reporting
section of the ArubaOS and
AirWave WebUIs. This vulnerability could potentially be used to
execute commands on the
controller with admin credentials.

NOTE: This vulnerability manifests when the administrator is
successfully logged in with
valid credentials and browses to the affected reporting sections of
the ArubaOS and AirWave
WebUIs.

CVSS v2 BASE METRIC SCORE: 4.8 (AV:A/AC:L/AU:N/C:P/I:P/A:N)

WORKAROUNDS

latest available patch on the Aruba support site corresponding to your
currently
installed release.

Advisory # 2:

TITLE

HTTP Response splitting vulnerability in ArubaOS Captive Portal Web
Interface

SUMMARY

A HTTP Response splitting vulnerability was discovered in ArubaOS's
Captive Portal Web
Interface where an attacker might be able to force authenticated
captive portal users to
bypass the custom welcome page post authentication and redirect them
to a site of
attacker's choice.

AFFECTED VERSIONS

    • ArubaOS 3.3.X, 3.4.X, 5.0.X, 6.0.X, 2.4.X-FIPS, 3.3.X-FIPS and
      3.4.X-FIPS

DETAILS

ArubaOS allows for authenticated captive portal users to be redirected
to a custom welcome
web page post authentication. A HTTP Response splitting vulnerability
was discovered that
could be exploited by an attacker to force authenticated captive
portal users to completely
bypass the custom welcome page and be redirected to a website of
attacker's choice. Attacker
might achieve this by sending a maliciously crafted URL to the user in
an email. When user
clicks on the link and authenticates successfully to the captive
portal, he/she might be
redirected to a site of attacker's choice rather than the captive
portal's custom welcome
page.

This vulnerability does not affect the default captive portal
configuration where no custom
welcome page is used.

IMPACT

An attacker could force an authenticated captive portal user to be
redirected to a website of
attacker's choice rather than captive portal's custom welcome page.
For this vulnerability to
manifest, user would have to click on a maliciously crafted link and
then authenticate
successfully to the presented captive portal authentication page.

NOTE: Default captive portal configuration is NOT vulnerable to this
issue where no custom
welcome page is configured.

CVSS v2 BASE METRIC SCORE: 4.9 (AV:N/AC:M/AU:S/C:P/I:P/A:N)

HOW TO IDENTIFY IF YOU ARE VULNERABLE

If the following lines exist in your configuration for a particular
active captive portal
profile then you are vulnerable.

aaa authentication captive-portal <profile>
    ...
    ...
    welcome-page <custom site>
!

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 welcome page all together. This will result in users
      directly landing at the site
      they requested.

      aaa authentication captive-portal <profile>
      no enable-welcome-page
      !

    • Disable custom welcome page. This will result in users being
      presented with default Aruba
      captive portal welcome page

      aaa authentication captive-portal <profile>
      no welcome-page
      !

SOLUTION

Aruba Networks recommends that all customers apply the appropriate
patch(es) as soon
as practical.

The following patches have the fix (any newer patch will also have the
fix):

    • Aruba OS 3.3.3.10
    • Aruba OS 3.4.4.2
    • Aruba OS 5.0.3.2
    • Aruba OS 6.0.1.1
    • Aruba OS 2.4.8.27-FIPS
    • Aruba OS 3.3.2.21-FIPS
    • Aruba OS 3.4.4.0-FIPS

The FIPS releases noted above are currently undergoing FIPS
certification and are
available from Aruba on request.

Please note: We highly recommend that you upgrade your Mobility
Controller to the
latest available patch on the Aruba support site corresponding to your
currently
installed release.
