Summary
Cisco Firepower Threat Defense Software Command Injection Vulnerabilities

Notes

Summary
Multiple vulnerabilities in the CLI of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to execute arbitrary commands with root privileges. For more information about these vulnerabilities, see the Details ["#details"] section of this advisory. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. This advisory is part of the October 2021 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: October 2021 Cisco ASA, FMC, and FTD Software Security Advisory Bundled Publication ["https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-74773"].
Vulnerable Products
These vulnerabilities affect Cisco FTD Software. For information about which Cisco software releases are vulnerable, see the Fixed Software ["#fs"] section of this advisory. Determine the Affected FTD Software Configuration In the following table, the left column indicates the Cisco FTD Software configuration and the right column indicates the associated Cisco CVE IDs that are described in the Details ["#details"] section of this advisory. Cisco FTD Configuration Associated CVE IDs Multi-instance1,2 CVE-2021-34755 and CVE-2021-34756 Default CVE-2021-34752 1. The multi-instance configuration is supported as of Cisco FTD Software Release 6.3.0, so earlier releases are not affected by these multi-instance vulnerabilities. 2. The only Cisco FTD Software platforms that support multi-instance operation are: Firepower 4100 Series Security Appliances Firepower 9300 Series Security Appliances Determine the Device Configuration Note: This section applies only to CVE-2021-34755 and CVE-2021-34756, which require multi-instance configuration. To determine whether a device is providing multi-instance services, log in to the Cisco FXOS CLI and use the show app-instance command within the ssa scope. If the Deploy Type field has a value of Container, application instances are present and the device is affected by this vulnerability. The following example shows the command output for an affected device: firepower# scope ssa firepower /ssa # show app-instance App Name Identifier Slot ID Admin State Oper State Running Version Startup Version Deploy Type Turbo Mode Profile Name Cluster State Cluster Role ----- ------- ------ ------ ----- ------- ------- ------ ----- ----- ------- ------- ftd ftd1 1 Enabled Online 6.2.3.14 6.2.3.14 Native No Not Applicable None ftd ftd2-1 2 Enabled Online 6.4.0.4 6.4.0.4 Container No mid Not Applicable None
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by this these vulnerabilities. Cisco has confirmed that these vulnerabilities do not affect Cisco Adaptive Security Appliance (ASA) Software or Cisco Firepower Management Center (FMC) Software.
Details
The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit another vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerabilities. Details about the vulnerabilities are as follows: CVE-2021-34755 and CVE-2021-34756: Cisco FTD Software Command Injection Vulnerabilities Multiple vulnerabilities in the CLI of Cisco FTD Software could allow an authenticated, local attacker to execute arbitrary commands with root privileges on the underlying operating system of an affected device that is running in multi-instance mode. These vulnerabilities are due to insufficient validation of user-supplied command arguments. An attacker could exploit these vulnerabilities by submitting crafted input to the affected command. A successful exploit could allow the attacker to execute commands with root privileges on the underlying operating system. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. Bug ID(s): CSCvx86283 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx86283"], CSCvy16559 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvy16559"] CVE IDs: CVE-2021-34755 and CVE-2021-34756 Security Impact Rating (SIR): High CVSS Base Score: 7.8 CVSS Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H CVE-2021-34752: Cisco FTD Software Command Injection Vulnerability A vulnerability in the CLI of Cisco FTD Software could allow an authenticated, local attacker with administrative privileges to execute arbitrary commands with root privileges on the underlying operating system of an affected device. This vulnerability is due to insufficient validation of user-supplied command arguments. An attacker could exploit this vulnerability by submitting crafted input to the affected commands. A successful exploit could allow the attacker to execute commands with root privileges on the underlying operating system. Cisco has released software updates that address this vulnerability.

Workarounds
There are no workarounds that address these vulnerabilities.
Fixed Software
Cisco has released free software updates that address the vulnerabilities described in this advisory. 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 ["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. When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page ["https://www.cisco.com/go/psirt"], 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 ["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. Fixed Releases In the following table(s), the left column lists Cisco software releases. The center column indicates whether a release is affected by the vulnerability described in this advisory and the first release that includes the fix for this vulnerability. The right column indicates whether a release is affected by any of the vulnerabilities described in this bundle and which release includes fixes for those vulnerabilities.
