Cisco HyperFlex Software Static Signing Key Vulnerability
Priority: High
Advisory ID: cisco-sa-20181003-hyperflex-secret
First Published: 2018 October 3 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCvj95632, CSCvk22858
CVE-2018-15382
CWE-642
CVSS Score: Base 8.6
CVSS: 3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H/E:X/RL:X/RC:X
Summary
A vulnerability in Cisco HyperFlex Software could allow an unauthenticated,
remote attacker to generate valid, signed session tokens.
The vulnerability is due to a static signing key that is present in all
Cisco HyperFlex systems. An attacker could exploit this vulnerability by
accessing the static signing key from one HyperFlex system and using it to
generate valid, signed session tokens for another HyperFlex system. A
successful exploit could allow the attacker to access the HyperFlex Web UI
of a system for which they are not authorized.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.

https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-hyperflex-secret
Affected Products
o Vulnerable Products
This vulnerability affects Cisco HyperFlex Software releases prior to 3.5
(1a).
Determining the HyperFlex Software Release
To determine the installed release of Cisco HyperFlex Software an
administrator may use either the CLI or the GUI.
Using the CLI, the administrator can issue the stcli about command. The
following example shows the output of the command for a device that is
running Cisco HyperFlex Software Release 3.0(1d):
root@hxcluster:~# stcli about
serviceType: stMgr
instanceUuid: c4f0441c-xxxx-xxxx-xxxx-xxxxxxxxxxxx
name: HyperFlex StorageController
locale: English (United States)
serialNumber: WZP#####OCD,WZP#####OG9,WZP########
apiVersion: 0.1
modelNumber: HX240C-M5L
build: 3.0.1d-29754 (internal)
displayVersion: 3.0(1d)
fullName: HyperFlex StorageController 3.0.1d
productVersion: 3.0.1d-29754
Using the GUI, the administrator can click the About link on the bottom
left of the page after logging in to HXConnect.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by 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 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 and Alerts 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
Cisco fixed this vulnerability in Cisco HyperFlex 3.5(1a).
Customers can download software updates from the Software Center on
Cisco.com by doing the following:
1. Click Browse all.
2. Navigate to Hyperconverged Infrastructure > HyperFlex HX Data Platform.
3. Access releases by using the left pane of the HyperFlex HX Data
Platform page.
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 vulnerability that is
described in this advisory.
Source
o This vulnerability was found during internal security testing.
