Summary
o A vulnerability in the web-based management interface of Cisco Adaptive
Security Appliance (ASA) Software could allow an unauthenticated, remote
attacker to conduct a cross-site request forgery (CSRF) attack on an
affected system.
The vulnerability is due to insufficient CSRF protections for the web-based
management interface on an affected device. An attacker could exploit this
vulnerability by persuading a user of the interface to follow a malicious
link. A successful exploit could allow the attacker to perform arbitrary
actions with the privilege level of the affected user. If the user has
administrative privileges, the attacker could alter the configuration of,
extract information from, or reload an affected device.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
This advisory is available at the following link:
https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-asa-csrf
Affected Products
o Vulnerable Products
This vulnerability affects Cisco products that are running a vulnerable
release of Cisco ASA Software and have web management access enabled.
For information about which Cisco ASA Software releases are vulnerable, see
the Fixed Software section of this advisory.
Determining Whether Web Management Access Is Configured
Administrators can use the show running-config http command to determine
whether web management access is enabled. The following example shows the
output of the command for a device that has the web management feature
enabled and that allows access to the web management feature from the
10.10.10.0/24 network via the Management interface:
ciscoasa# show running-config http
http server enable
http 10.10.10.0 255.255.255.0 Management
Note: The device is vulnerable to requests only when they are sent from an
IP address in the range configured in the http <remote_ip_address>
<remote_subnet_mask> <interface_name> command.
Determining the Cisco ASA Software Release
To determine which Cisco ASA Software release is running on a device,
administrators can log in to the device, use the show version | include
Version command in the CLI, and refer to the output of the command. The
following example shows the output of the command for a device that is
running Cisco ASA Software Release 9.9.2.18:
ciscoasa# show version | include Version
Cisco Adaptive Security Appliance Software Version 9.9.2.18
Device Manager Version 7.4(1)
.
.
.
If a device is managed by using Cisco Adaptive Security Device Manager
(ASDM), administrators can also determine which release is running on a
device by referring to the release information in the table that appears in
the Cisco ASDM login window or the Device Dashboard tab of the Cisco ASDM
Home pane.
