Cisco Firepower Management Center Software and Firepower Threat Defense
Software Directory Traversal Vulnerability

Priority:        High

Advisory ID:     cisco-sa-ftdfmc-dirtrav-NW8XcuSB

First Published: 2020 October 21 16:00 GMT

Version 1.0:     Final

Workarounds:     No workarounds available

Cisco Bug IDs:   CSCvp56744

CVE-2020-3550    

CWE-22

CVSS Score:
8.1  AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N/E:X/RL:X/RC:X

Summary

  o A vulnerability in the sfmgr daemon of Cisco Firepower Management Center
    (FMC) Software and Cisco Firepower Threat Defense (FTD) Software could
    allow an authenticated, remote attacker to perform directory traversal and
    access directories outside the restricted path.

    The vulnerability is due to insufficient input validation. An attacker
    could exploit this vulnerability by using a relative path in specific sfmgr
    commands. An exploit could allow the attacker to read or write arbitrary
    files on an sftunnel-connected peer device.

    Cisco has released software updates that address the vulnerability
    described in this advisory. 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-ftdfmc-dirtrav-NW8XcuSB

    This advisory is part of the October 2020 Cisco ASA, FMC, and FTD Software
    Security Advisory Bundled Publication, which includes 17 Cisco Security
    Advisories that describe 17 vulnerabilities. For a complete list of the
    advisories and links to them, see Cisco Event Response: October 2020 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 FMC or FTD Software. Devices that are running Cisco FTD
    Software are affected only if they are registered to a Cisco FMC.

    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 or Cisco Firepower Device Manager (FDM)
    Software.

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 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.

    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.

    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

Cisco Firepower Management Center Software and Firepower Threat Defense
Software sftunnel Pass the Hash Vulnerability

Priority:        High

Advisory ID:     cisco-sa-ftdfmc-sft-mitm-tc8AzFs2

First Published: 2020 October 21 16:00 GMT

Version 1.0:     Final

Workarounds:     No workarounds available

Cisco Bug IDs:   CSCvp56719

CVE-2020-3549    

CWE-326

CVSS Score:
8.1  AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:X/RL:X/RC:X

Summary

  o A vulnerability in the sftunnel functionality of Cisco Firepower Management
    Center (FMC) Software and Cisco Firepower Threat Defense (FTD) Software
    could allow an unauthenticated, remote attacker to obtain the device
    registration hash.

    The vulnerability is due to insufficient sftunnel negotiation protection
    during initial device registration. An attacker in a man-in-the-middle
    position could exploit this vulnerability by intercepting a specific flow
    of the sftunnel communication between an FMC device and an FTD device. A
    successful exploit could allow the attacker to decrypt and modify the
    sftunnel communication between FMC and FTD devices, allowing the attacker
    to modify configuration data sent from an FMC device to an FTD device or
    alert data sent from an FTD device to an FMC device.

    Cisco has released software updates that address the vulnerability
    described in this advisory. There are no workarounds that address this
    vulnerability.
