Cisco Adaptive Security Device Manager and Adaptive Security Appliance Software
Client-side Arbitrary Code Execution Vulnerability
Priority: Medium
Advisory ID: cisco-sa-asa-asdm-sig-NPKvwDjm
First Published: 2022 June 22 16:00 GMT
Last Updated: 2022 August 10 15:49 GMT
Version 1.1: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCwb05264 CSCwb05291
CVE Names: CVE-2022-20829
CWEs: CWE-345
Summary
o A vulnerability in the packaging of Cisco Adaptive Security Device Manager
(ASDM) images and the validation of those images by Cisco Adaptive Security
Appliance (ASA) Software could allow an authenticated, remote attacker with
administrative privileges to upload an ASDM image that contains malicious
code to a device that is running Cisco ASA Software.
This vulnerability is due to insufficient validation of the authenticity of
an ASDM image during its installation on a device that is running Cisco ASA
Software. An attacker could exploit this vulnerability by installing a
crafted ASDM image on the device that is running Cisco ASA Software and
then waiting for a targeted user to access that device using ASDM. A
successful exploit could allow the attacker to execute arbitrary code on
the machine of the targeted user with the privileges of that user on that
machine.
Notes:
To successfully exploit this vulnerability, the attacker must have
administrative privileges on the device that is running Cisco ASA
Software.
Potential targets are limited to users who manage the same device that
is running Cisco ASA Software using ASDM.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.

Affected Products
o Vulnerable Products
At the time of publication, this vulnerability affected Cisco devices if
all of the following were true:
The device was running a Cisco ASA Software release earlier than
Release 9.16.3.19, earlier than Release 9.17.1.13, or earlier than
Release 9.18.2.
The device was configured with a Cisco ASDM release earlier than
Release 7.18.1.152.
The Cisco ASDM image was using a Cisco ASDM-IDM Launcher release
earlier than Release 1.9(5).
The device was configured for HTTPS management access.
For information about which Cisco software releases were vulnerable at the
time of publication, see the Fixed Software section of this advisory. See
the Details section in the bug ID(s) at the top of this advisory for the
most complete and current information.
Determine the HTTPS Management Access Configuration
To identify the status of HTTPS management access, use the show
running-config http CLI command. The following example shows the output of
the show running-config http command on a device that has HTTPS management
access enabled on the inside interface:
asa# show running-config http
http server enable
http 0.0.0.0 0.0.0.0 inside
The HTTPS management access is disabled if one of the following is true:
The line starting with http server enable is missing.
The output of the show running-config http command does not include an
HTTP access control list (ACL) that is associated with an interface.
If the output does include an HTTP ACL, the exact value of the ACL does not
affect the vulnerability status of the device. However, potential targets
are limited to users who connect to the HTTPS management server of the
device from an IP address that is permitted by the HTTP ACL.
If the line starting with http server enable does not include a port, as in
the example above, the default port 443 is used. The exact port value does
not affect the vulnerability status of the device.
Determine the ASDM Image Configuration
To determine the configured ASDM image, use the show running-config asdm |
include image CLI command. The following example shows the output of the
show running-config asdm | include image command on a device that is
configured to use the ASDM image named asdm-7181.bin on the disk0:
filesystem:
asa# show running-config asdm | include image
asdm image disk0:/asdm-7181.bin
Empty output of this command indicates that no ASDM image is configured.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
Cisco has confirmed that this vulnerability does not affect the following
Cisco products:
Firepower Management Center (FMC) Software
Firepower Threat Defense (FTD) Software
Next-Generation Intrusion Prevention System (NGIPS) Software
Workarounds
o There are no workarounds that address this vulnerability.
Fixed Software
o When considering software upgrades , customers are advised to regularly
consult the advisories for Cisco products, which are available from the
Cisco Security Advisories page , to determine exposure and a complete
upgrade solution.
In all cases, customers should ensure that the devices to be upgraded
contain sufficient memory and confirm that current hardware and software
configurations will continue to be supported properly by the new release.
If the information is not clear, customers are advised to contact the Cisco
Technical Assistance Center (TAC) or their contracted maintenance
providers.
Fixed Releases
At the time of publication, the release information in the following table
(s) was accurate. See the Details section in the bug ID(s) at the top of
this advisory for the most complete and current information.
The left column lists Cisco software releases, and the right column
indicates whether a release was affected by the vulnerability that is
described in this advisory and which release included the fix for this
vulnerability.
Notes:
Updating both Cisco ASA Software and Cisco ASDM Software is required to
fully fix this vulnerability.
After the ASDM image has been updated on a device that is running Cisco
ASA Software, user machines that are running Cisco ASDM Software will
automatically be updated with the new ASDM release when they first
connect to the device.
Once user machines have successfully updated, they will be running
Cisco ASDM-IDM Launcher Release 1.9(5) or later.
