Cisco Firepower Threat Defense Software and Firepower Management Center
Software Code Injection Vulnerability
Priority: High
Advisory ID: cisco-sa-ftd-fmc-code-inj-wSHrgz8L
First Published: 2023 November 1 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCwb42031
CVE Names: CVE-2023-20063
Summary
o A vulnerability in the inter-device communication mechanisms between
devices that are running Cisco Firepower Threat Defense (FTD) Software and
devices that are running Cisco Firepower Management (FMC) Software could
allow an authenticated, local attacker to execute arbitrary commands with
root permissions on the underlying operating system of an affected device.
This vulnerability is due to insufficient validation of user-supplied
input. An attacker could exploit this vulnerability by accessing the expert
mode of an affected device and submitting specific commands to a connected
system. A successful exploit could allow the attacker to execute arbitrary
code in the context of an FMC device if the attacker has administrative
privileges on an associated FTD device. Alternatively, a successful exploit
could allow the attacker to execute arbitrary code in the context of an FTD
device if the attacker has administrative privileges on an associated FMC
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://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-fmc-code-inj-wSHrgz8L
This advisory is part of the November 2023 release of the Cisco ASA, FTD,
and FMC Security Advisory Bundled publication. For a complete list of the
advisories and links to them, see Cisco Event Response: November 2023
Semiannual Cisco ASA, FMC, and FTD Software Security Advisory Bundled
Publication .
Affected Products
o Vulnerable Products
This vulnerability affects Cisco products if they are running a vulnerable
release of Cisco FTD Software or Cisco FMC Software and they are configured
to allow administrators to use expert mode. By default, expert mode is
accessible to any administrator.
For information about which Cisco software releases are vulnerable, see the
Fixed Software section of this advisory.
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 Cisco Adaptive
Security Appliance (ASA) Software .
Details
o The vulnerability described in this advisory presents a considerable
security risk only when the individuals in charge of managing Cisco FTD
devices are different from the individuals in charge of managing the
associated Cisco FMC Software. If the same people have Administrator
privileges over both the Cisco FTD Software and the connected Cisco FMC
Software, an attacker would not gain any additional privileges by
exploiting this vulnerability.
Workarounds
o There are no workarounds that address this vulnerability.
Fixed Software
o Cisco has released free software updates that address the vulnerability
described in this advisory. Customers with service contracts that entitle
them to regular software updates should obtain security fixes through their
usual update channels.
Customers may only install and expect support for software versions and
feature sets for which they have purchased a license. By installing,
downloading, accessing, or otherwise using such software upgrades,
customers agree to follow the terms of the Cisco software license:
https://www.cisco.com/c/en/us/products/end-user-license-agreement.html
Additionally, customers may only download software for which they have a
valid license, procured from Cisco directly, or through a Cisco authorized
reseller or partner. In most cases this will be a maintenance upgrade to
software that was previously purchased. Free security software updates do
not entitle customers to a new software license, additional software
feature sets, or major revision upgrades.
The Cisco Support and Downloads page on Cisco.com provides information
about licensing and downloads. This page can also display customer device
support coverage for customers who use the My Devices tool.
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.
Customers Without Service Contracts
Customers who purchase directly from Cisco but do not hold a Cisco service
contract and customers who make purchases through third-party vendors but
are unsuccessful in obtaining fixed software through their point of sale
should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c
/en/us/support/web/tsd-cisco-worldwide-contacts.html
Customers should have the product serial number available and be prepared
to provide the URL of this advisory as evidence of entitlement to a free
upgrade.
Cisco ASA, FMC, and FTD Software
To help customers determine their exposure to vulnerabilities in Cisco ASA,
FMC, and FTD Software, Cisco provides the Cisco Software Checker . This
tool identifies any Cisco security advisories that impact a specific
software release and the earliest release that fixes the vulnerabilities
that are described in each advisory ("First Fixed"). If applicable, the
tool also returns the earliest release that fixes all the vulnerabilities
that are described in all the advisories that the Software Checker
identifies ("Combined First Fixed").
To use the tool, go to the Cisco Software Checker page and follow the
instructions. Alternatively, use the following form to search for
vulnerabilities that affect a specific software release. To use the form,
follow these steps:
1. Choose which advisories the tool will search-all advisories, only
advisories with a Critical or High Security Impact Rating (SIR) , or
only this advisory.
2. Choose the appropriate software.
3. Choose the appropriate platform.
4. Enter a release number-for example, 9.16.2.11 for Cisco ASA Software or
6.6.7 for Cisco FTD Software.
5. Click Check .
