Impact
======

An attacker with knowledge of the Default Usernames and Passwords
Vulnerability accounts could modify the device configuration and, in
certain instances, gain user access to the host operating system.

An exploit of the Privilege Escalation Vulnerability could allow an
authenticated attacker to execute host operating system
administrative commands.

Successful exploitation of the Crafted SSH Packet Vulnerability,
Crafted SNMPv2 Packet Vulnerability, and Crafted SNMPv3 Packet
Vulnerability may cause a reload of the affected device. Repeated
exploitation could result in a sustained DoS condition.

Workarounds
===========

This Security Advisory describes multiple distinct vulnerabilities.
These vulnerabilities and their respective workarounds are
independent of each other.

Default Usernames and Passwords
+------------------------------

To change the default administrative password, use the username
command in configuration mode. The syntax of this command is as
follows:

username admin [password [0 | 5] {password}]

The keywords, arguments, and options are:

admin--Specifies the default administrative user name.

password--(Optional) Keyword that indicates that a password follows.

0--(Optional) Specifies a clear text password.

5--(Optional) Specifies an MD5-hashed strong encryption password.

password--The password in clear text, encrypted text, or MD5 strong
encryption, depending on the numbered option (0 or 5) that you enter.
If you do not enter a numbered option, the password is in clear text
by default. Enter a password as an unquoted text string with a
maximum of 64 characters.

For example, to create a user named admin that uses the clear text
password my_super_secret_88312, enter the following command:

ACE(config)# username admin password 0 my_super_secret_88312

Note: This process can also be followed to change the www user
account credentials. The dm user is for accessing the Device Manager
GUI and cannot be modified or deleted. The dm user is an internal
user required by the Device Manager GUI; it is hidden on the ACE CLI.
For more information refer to:
http://www.cisco.com/en/US/docs/app_ntwk_services/data_center_app_services/ace_appliances/vA3_1_0/configuration/virtualization/guide/config.html

Privilege Escalation Vulnerability
+---------------------------------

There are no workarounds for this vulnerability.

Crafted SSH Packet Vulnerability
+-------------------------------

SSH management traffic that can be received by the ACE is controlled
through the use of class maps, policy maps, and service policies.

This Management Traffic Service example denies unauthorized SSH
packets that are sent to an affected device. In the following
example, 192.168.100.1 is considered a trusted source that requires
SSH access to the affected device. Care should be taken to allow all
required management access to the affected device. An attacker could
exploit this vulnerability using spoofed packets. This workaround
cannot provide complete protection against this vulnerability when
the attack comes from a trusted source address.

The following example demonstrates how SSH access to the ACE is only
allowed from the 192.168.100.1 host:


!-- Configure a class to allow SSH from the trusted source
!

class-map type management match-all Permit_SSH_Class
description Allow SSH from trusted sources Class
match protocol ssh source-address 192.168.100.1 255.255.255.255

!
!-- Configure a management policy that allows ssh from the
!--trusted source configured in the above class
!

policy-map type management first-match Permit_SSH_Policy
description Allow SSH from trusted sources Policy
class Permit_SSH_Class
permit

!
!-- Apply the management policy globally
!

service-policy input Permit_SSH_Policy

Additional information about "Configuring Class Maps and Policy Maps"
is available at:

http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A1/configuration/administration/guide/mapolcy.html

warning Warning: It is possible to easily spoof the sender's IP
address, which may defeat class maps and access control lists (ACLs)
that permit communication to the device from trusted IP addresses.

Crafted SNMPv2 and SNMPv3 Packet Vulnerabilities
+-----------------------------------------------

SNMP management traffic that can be received by the ACE is controlled
through the use of class maps, policy maps, and service policies.

This Management Traffic Service example denies unauthorized SNMP
packets on UDP port 161 that are sent to an affected device. In the
following example, 192.168.100.1 is considered a trusted source that
requires SNMP access to the affected device. Care should be taken to
allow all required management access to the affected device. An
attacker could exploit this vulnerability using spoofed packets. This
workaround cannot provide complete protection against this
vulnerability when the attack comes from a trusted source address.


!-- Configure a class to allow SNMP from the trusted source
!

class-map type management match-all Permit_SNMP_Class
description Allow SNMP from trusted sources Class
2 match protocol snmp source-address 192.168.100.1 255.255.255.255


!
!-- Configure a management policy that allows snmp from the
!--trusted source configured in the above class
!

policy-map type management first-match Permit_SNMP_Policy
description Allow SNMP from trusted sources Policy
class Permit_SNMP_Class
permit

!-- Apply the management policy globally
!

service-policy input Permit_SNMP_Policy
