TITLE

GNU Bash CVE-2014-6278 Incomplete Fix Remote Code Execution Vulnerability

DESCRIPTION

GNU Bash through 4.3 bash43-026 does not properly parse function definitions in the values of environment variables, which allows remote attackers to execute arbitrary commands via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271, CVE-2014-7169, and CVE-2014-6277. GNU Bash is prone to remote code execution vulnerability. An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition. Note: HP and the switch vendor recommend running an active version of Fabric OS (FOS) listed on the HP Single Point of Connectivity Knowledge (SPOCK) website ( http://h20272.www2.hp.com/ ) and applying the work-around information provided in the MITIGATION INFORMATION section below to protect HP StoreFabric B-series switches from this vulnerability. - Utilize FOS password policy management to strengthen the complexity, age, and history requirements of switch account passwords.

This bulletin will be revised when the update is available. MITIGATION INFORMATION HP recommends the following steps to reduce the risk of this vulnerability: - Place the HP StoreFabric H-series switch and other data center critical infrastructure behind a firewall to disallow access from the Internet. - Change all HP StoreFabric switch default account passwords, including the root passwords, from the default factory passwords. - Examine the list of accounts, including ones on the switch and those existing on remote authentication servers such as RADIUS, LDAP, and TACAS+, to ensure only necessary personnel can gain access to HP StoreFabric H-series switches. Delete guest accounts and temporary accounts created for one-time usage needs. - To avoid possible exploit through the embedded web GUI, QuickTools, disable the web server with the following procedure: NOTE: After completing this procedure, the user will not be able to manage the switch using QuickTools. Login to the Command Line Interface (CLI). Execute the "admin start" command to enter into an admin session. Execute the "set setup services" command and change setting for EmbeddedGUIEnabled to "False".

CVE identifiers CVE-2014-6271, CVE-2014-7169, CVE-2014-7186, CVE-2014-7187, CVE-2014-6277, and CVE-2014-6278 have been assigned to these vulnerabilities. The CA Technologies Enterprise Information Security team has led a global effort to identify and remediate systems and products discovered with these vulnerabilities. We continue to patch our systems as fixes become available, and we are providing fixes for affected CA Technologies products. CA Technologies continues to aggressively scan our environments (including servers, networks, external facing applications, and SaaS environments) to proactively monitor, identify, and remediate any vulnerability when necessary. Risk Rating High Platform AIX Android (not vulnerable, unless rooted) Apple iOS (not vulnerable unless jailbroken) Linux Mac OS X Solaris Windows (not vulnerable unless Cygwin or similar ported Linux tools with Bash shell are installed) Other UNIX/BSD based systems if Bash is installed Any other OS or JeOS that utilizes Bash Affected Products The following products have been identified as potentially vulnerable, and we have made fixes available for all of these products. CA API Management (Linux appliance only) CA Application Performance Management (TIM is the only affected APM component) CA Application Performance Management Cloud Monitor CA Customer Experience Manager (CEM) Transaction Impact Monitor (TIM) CA Layer 7 products (API Gateway, Mobile Access Gateway, API Management Portal) CA User Activity Reporting Module (Enterprise Log Manager) Note: This security notice will be updated if other CA Technologies products are determined to be vulnerable. In most cases, the Bash vulnerabilities will need to be patched by OS vendors. Exceptions may include CA Technologies appliances, and software products that include Linux, UNIX or Mac OS X based operating systems (that include Bash). Affected Components CentOS Cygwin GNU Bash Red Hat Enterprise Linux SUSE Linux Non-Affected Products IMPORTANT NOTE: This listing includes only a small subset of the unaffected CA Technologies products. We're including unaffected products that customers have already inquired about. While the following CA Technologies products are not directly affected by the Bash vulnerabilities, the underlying operating systems that CA Technologies software is installed on may be vulnerable. We strongly encourage our customers to follow the recommendations provided by their vendors for all operating systems they utilize. All CA SaaS / On Demand products were either not vulnerable or have already been patched. CA AHS / PaymentMinder - AHS App is not vulnerable. The AHS app does not execute CGI scripts, or spawn or execute shell commands from within the app. AHS infrastructure already patched. CA Asset Portfolio Management CA AuthMinder (Arcot WebFort) CA AuthMinder for Business Users CA AuthMinder for Consumers CA AutoSys products - We use the bash shell that comes with the operating system and the customer is responsible for patching their OS. Additionally, the agents themselves do not distribute any scripts that use bash. CA Clarity On Demand CA CloudMinder - CloudMinder does not include the Bash Shell in BoM, or use it, but because we are deployed on RHEL, customers may be indirectly affected. Customers using RHEL should apply patches provided by Red Hat. CA Console Management for OpenVMS - Our OpenVMS products do not bundle bash, and they do not supply bash scripts; we use nothing but the native DCL CLI. CA ControlMinder CA DataMinder (formerly DLP) products – Software and appliance confirmed not vulnerable. Note: Linux Agents shipped, but no public SSH or Web apps are used in these agents. Customers should patch bash shell on any Linux server with DataMinder agents. DataMinder agents should continue to function normally. CA Digital Payments SaaS (previously patched) CA Directory CA eCommerce SaaS / On Demand (previously patched) CA Endevor Software Change Manager CA Federation (formerly SiteMinder Federation) CA GovernanceMinder CA IdentityMinder CA Infrastructure Management CA JCLCheck CA Job Management for OpenVMS - Our OpenVMS products do not bundle bash, and they do not supply bash scripts; we use nothing but the native DCL CLI. CA NetQoS GigaStor Observer Expert CA Network Flow Analysis CA Performance Management for OpenVMS - Our OpenVMS products do not bundle bash, and they do not supply bash scripts; we use nothing but the native DCL CLI. CA RiskMinder CA Service Desk Manager CA Service Operations Insight (SOI) CA SiteMinder CA SOLVE:Access CA Spectrum for Linux - Not vulnerable. Be sure to apply bash fixes from your underlying operating system vendor. CA Strong Authentication CA System Watchdog for OpenVMS - Our OpenVMS products do not bundle bash, and they do not supply bash scripts; we use nothing but the native DCL CLI. CA Top Secret CA Universal Job Management Agent for OpenVMS - Our OpenVMS products do not bundle bash, and they do not supply bash scripts; we use nothing but the native DCL CLI. CA Virtual Assurance for Infrastructure Managers (VAIM) Solution CA Technologies has issued the following fixes to address the vulnerabilities. CA API Management: Patches for Linux appliance are available through CA Support to customers of Gateway (applicable for all versions – 6.1.5, 6.2, 7.0, 7.1, 8.0, 8.1, 8.1.1, 8.1.02). CA Application Performance Management: KB article for APM TIM has been published. APM TIM is the only part of APM that was affected. Refer to TEC618037. CA Application Performance Management Cloud Monitor: New images are available for subscribers. Download the latest OPMS version 8.2.1.5. For assistance, contact CA Support. CA Customer Experience Manager (CEM) Transaction Impact Monitor (TIM): Very low risk. 9.6 is not affected. 9.5 Installation uses Bash. We do not use Bash at all for the CEM operating system that we have shipped in the past. This means that customers who patch the OS will not impact the ability of the CEM TIMsoft from operating. However prior to version 9.6, the TIM installation script does use the bash shell. See new KB article TEC618037 for additional information. CA Layer 7 (API Gateway, Mobile Access Gateway, API Management Portal): Fixes for all Bash vulnerabilities and a security bulletin are available on the Layer 7 Support website. CA User Activity Reporting Module (Enterprise Log Manager): All 12.5 and 12.6 GA versions are potentially affected. Patches provided on 2014-09-30. To get the patch, use the OS update functionality to get the latest R12.6 SP1 subscription update. Note that you can update R12.5 SPx with the R12.6 SP1 OS update. For assistance, contact CA Support. Workaround None To help mitigate the risk, we do strongly encourage all customers to follow patch management best practices, and in particular for operating systems affected by the Bash Shellshock vulnerabilities.

Software Description: - bash: GNU Bourne Again SHell Details: Michal Zalewski discovered that Bash incorrectly handled parsing certain function definitions. If an attacker were able to create an environment variable containing a function definition with a very specific name, these issues could possibly be used to bypass certain environment restrictions and execute arbitrary code. (CVE-2014-6277, CVE-2014-6278) Please note that the previous Bash security update, USN-2364-1, includes a hardening measure that prevents these issues from being used in a Shellshock attack. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: bash 4.3-7ubuntu1.5 Ubuntu 12.04 LTS: bash 4.2-2ubuntu2.6 Ubuntu 10.04 LTS: bash 4.1-2ubuntu3.5 In general, a standard system update will make all the necessary changes. References: http://www.ubuntu.com/usn/usn-2380-1 CVE-2014-6277, CVE-2014-6278 Package Information: https://launchpad.net/ubuntu/+source/bash/4.3-7ubuntu1.5 https://launchpad.net/ubuntu/+source/bash/4.2-2ubuntu2.6 https://launchpad.net/ubuntu/+source/bash/4.1-2ubuntu3.5 . This vulnerability allows users that have been granted access to a shell script to escalate privilege and execute unrestricted commands at the same security level as the Bash script. Customers who need to upgrade the firmware of their Superdome X or HP Converged System 900 for SAP HANA should contact HP Technical Support to obtain the firmware or plan to schedule an onsite visit with an HP Services field service professional. Patch and maintain Lightweight Directory Access Protocol (LDAP) and web servers. Use virus scanners, intrusion detection/prevention systems (IDS/IPS), and vulnerability scanners regularly. NOTE: This vulnerability can only be exploited if the attacker already has valid administrative login credentials
