Cisco Firepower Management Center Software Command Injection Vulnerabilities
Priority: Medium
Advisory ID: cisco-sa-fmc-cmd-inj-Z3B5MY35
First Published: 2022 November 9 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCwb23029 CSCwb23048
CVE Names: CVE-2022-20925 CVE-2022-20926
CWEs: CWE-77
Summary
o Multiple vulnerabilities in the web management interface of Cisco Firepower
Management Center (FMC) Software could allow an authenticated, remote
attacker to execute arbitrary commands on the underlying operating system.
These vulnerabilities are due to insufficient validation of user-supplied
parameters for certain API endpoints. An attacker could exploit these
vulnerabilities by sending crafted input to an affected API endpoint. A
successful exploit could allow an attacker to execute arbitrary commands on
the device with low system privileges. To successfully exploit these
vulnerabilities, an attacker would need valid credentials for a user who
has Devices permissions. By default, only Administrator, Security Approver
and Network Admin roles have these permissions.
Cisco has released software updates that address these vulnerabilities.
There are no workarounds that address these vulnerabilities.
This advisory is available at the following link:
https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-cmd-inj-Z3B5MY35
This advisory is part of the November 2022 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 2022
Semiannual Cisco ASA, FMC, and FTD Software Security Advisory Bundled
Publication .
Affected Products
o Vulnerable Products
At the time of publication, these vulnerabilities affected Cisco FMC
Software.
For information about which Cisco software releases are vulnerable at the
time of publication, 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 these vulnerabilities.
Cisco has confirmed that these vulnerabilities do not affect the following
Cisco products:
Firepower Threat Defense (FTD) Software
Adaptive Security Appliance (ASA) Software
Workarounds
o There are no workarounds that address these vulnerabilities.
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.
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 (for Cisco ASA and FTD Software only).
4. Enter a release number-for example, 16.2.11 for Cisco ASA Software or
6.6.7 for Cisco FTD Software.
5. Click Check .
Exploitation and Public Announcements
o The Cisco Product Security Incident Response team (PSIRT) is not aware of
any public announcements or malicious use of the vulnerabilities that are
described in this advisory.
Source
o These vulnerabilities were found by Brandon Sakai of Cisco during internal
security testing.
Cisco Security Vulnerability Policy
o To learn about Cisco security vulnerability disclosure policies and
publications, see the Security Vulnerability Policy . This document also
contains instructions for obtaining fixed software and receiving security
vulnerability information from Cisco.
