Hello, I have tested the vulnerability and confirmed that it affects ACS 5.2. ACS 5.3 probably runs the same BASH version, so the it is most likely vulnerable. At this point, I would recommend to upgrade to any of the following versions: ACS 5.4 patch 7 ACS 5.5 patch 6 ACS 5.6 patch 1 HTH.

Hello, Well, if the RADIUS debug output does not list the attribute 25 then the server is not sending it. Did you follow the configuration steps indicated in the configuration guide of the RSA AM product? Unfortunately, it sounds like a configuration issue on the server side. HTH.

Hi, So you need to perform MAB authentication. As you mentioned, you will need to create a DB of MAC entries. In order to configure the Windows server (2003 or 2008?) to assign the dynamic VLAN you need to define the Remote Access Policies and create the custom attributes. For example: Tunnel-Medium-Type. Select a value appropriate to the previous selections you have made for the policy. For example, if the network policy you are configuring is a wireless policy, select Value: 802 (Includes all 802 media plus Ethernet canonical format). Tunnel-Pvt-Group-ID. Enter the integer that represents the VLAN number to which group members will be assigned. Tunnel-Type. Select Virtual LANs (VLAN). You can find more information here: Configure a Network Policy for VLANs VLAN Attributes Used in Network Policy 802.1X Authentication Services Configuration Guide, Cisco IOS XE Release 3SE (Catalyst 3850 Switches) HTH.

Hi, Are you connecting to the RSA server over sdi or Radius? If Radius, you could run the "debug radius all" on the ASA to check whether the attribute 25 comes back from the RSA server. HTH.

Oi Nathan, Você está usando RADIUS ou LDAP para autenticar seus usuários? Radius, por padrão, protege a senha, mas não o nome do usuário. Se você estiver usando Radius, eu não esperaria que a senha a ser enviada em texto puro. Portu.

Recently, we have seen many issues with ACS changes not taking effect or wrong policies being hit. This seems to be caused by unsupported web browsers used to manage the ACS view database i.e. make changes through the GUI. The bugs are the following: CSCuo93378 Certain browsers cause ACS database corruption CSCuo88797 ACS 5.x should display message if unsupported browser is used for GUI. I strongly recommend you to use supported web browsers to make any changes. Refer to the next link for further information about your specific ACS version: ACS 5.3 Supported web browsers ACS 5.4 Supported web browsers ACS 5.5 Supported web browsers Best Regards, Javier Portuguez, AAA and VPN engineer.

Sokmeng, To begin with, I think you should open a new case since this one was opened for another reason. Now, if you turn on debugs on the ASA, what do you see? The transform-set may be wrong, make sure you have one in tunnel mode, so the Cisco VPN client uses it to establish the connection. HTH.

It sounds good. Just make sure to install the Pointed patch before upgrading to 5.5. Thanks,
