Summary
Cisco HyperFlex Software Static Signing Key Vulnerability

Notes

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. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-hyperflex-secret ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-hyperflex-secret"]
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 ["#vp"] section of this advisory are known to be affected by this vulnerability.
Workarounds
There are no workarounds that address this vulnerability.
Fixed Software
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 ["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 ["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 Cisco fixed this vulnerability in Cisco HyperFlex 3.5(1a). Customers can download software updates from the Software Center ["https://software.cisco.com/download/home"] on Cisco.com by doing the following: Click Browse all. Navigate to Hyperconverged Infrastructure > HyperFlex HX Data Platform. Access releases by using the left pane of the HyperFlex HX Data Platform page.
