TITLE

Cisco Mediator Framework Vulnerabilities that gain access privileges

DESCRIPTION

Cisco Mediator Framework 1.5.1 before 1.5.1.build.14-eng, 2.2 before 2.2.1.dev.1, and 3.0 before 3.0.9.release.1 on the Cisco Network Building Mediator NBM-2400 and NBM-4800 and the Richards-Zeta Mediator 2500 has a default password for the administrative user account and unspecified other accounts, which makes it easier for remote attackers to obtain privileged access, aka Bug ID CSCtb83495. The problem is Bug ID : CSCtb83495 It is a problem.Access rights may be obtained by a third party. Cisco Network Building Mediator (NBM) products are affected by multiple vulnerabilities that could allow an attacker to gain control of a vulnerable device or to cause a denial of service. The Cisco Network Building Mediator is a smart, interconnected building solution that intelligently interconnects and operates heating, ventilation and cooling systems (HVAC), lighting, power, security, and renewable energy systems over IP networks. There are several security vulnerabilities in Cisco Network Building Mediator, as follows: - Default Authentication Credentials (CVE-2010-0595): Multiple predefined users on the device, including administrator user accounts using default authentication information, any network access device Users can log in to the control system as an administrator.-Privilege Escalation (CVE-2010-0596, CVE-2010-0597): Vulnerability allows unauthorized users to read and modify device configurations, malicious users must be able to successfully authenticate, but do not require administrator privileges Or modify the device configuration if you know the administrator to verify the credentials. Both vulnerabilities need to be attacked via HTTP or HTTPS transport protocol. In addition, Cisco bug ID CSCtb83618 (CVE-2010-0597) vulnerability can be used for heavy-duty devices, continuous exploitation of vulnerabilities Can lead to denial of service attacks. - Unauthorized information interception (CVE-2010-0598, CVE-2010-0599): Operator workstation Cisco Network Building Mediator did not protect unauthorized interception of sessions, malicious users could intercept sessions, obtain arbitrary authentication information, and use this information to control devices. CVE-2010-0598 related vulnerabilities allow malicious users to intercept HTTP session access The administrator verifies the credentials. CVE-2010-0599 related vulnerabilities allow malicious users to intercept XML RPC session access administrator authentication credentials. - Unauthorized Information Access (CVE-2010-0600): Malicious users can read system configuration files, configuration files Contains user account information, including passwords. Attackers can perform attacks and read configuration files via XML RPC or XML RCP over the HTTPS protocol. An attacker can exploit this issue to gain unauthorized administrative access to the affected device. Successful exploits will result in the complete compromise of the affected device. These vulnerabilities also affect the legacy Richards-Zeta Mediator products. This security advisory outlines details of the following vulnerabilities: * Default credentials * Privilege escalation * Unauthorized information interception * Unauthorized information access Cisco has released free software updates that address these vulnerabilities. Workarounds that mitigate some of the listed vulnerabilities are available. All Mediator Framework software releases prior to 3.1.1 are affected by all vulnerabilities listed in this security advisory.

Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the software table below names a Mediator Framework software release. If a given software release is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. Cisco recommends upgrading to the latest available release where possible. All vulnerabilities are fixed in Mediator Framework release 3.1.1 and above. Mediator Framework release 3.1.1 is the recommended migration path for all Mediator Framework releases. Vulnerabilities do not affect Mediator Operating Environment. To obtain fixed 1.5.1 and 2.2 Mediator Framework software and configTOOL version 3.1.0b1 contact Cisco TAC. Privilege escalation +------------------- There are no workarounds for these vulnerabilities. Unauthorized information interception +------------------------------------ The following workaround is applicable only to the vulnerability related to HTTP protocol. There is no workaround for the vulnerability that affects XML RPC service. The HTTPS service is enabled and running by default and no further actions are needed to enable it. The HTTP service can be disabled with configTOOL. Inside the Node tree pane, expand theservices tab, and then expand tab the network tab. Click the http_server tab, and then click the Enabled to uncheck it. Unauthorized information access +------------------------------ There is no workaround for this vulnerability. In the following examples it is assumed that the operator console has IP address 192.0.2.1. The 192.0.2.1 address must be changed to match the IP address used by the designated operator console. The following code must be entered on the console. Please refer to section 2.4 in the user guide at http://www.cisco.com/en/US/docs/security/physical_security/cnbm/User/guide/CNBM__UG.pdf for information on how to connect to the serial port using hyper-terminal. # The following rule establishes a default policy for INPUT rule chain. # The default policy is to drop all packets unless they are explicitly # permitted by a rule in the INPUT chain iptables -P INPUT DROP # This rule will allow all traffic from operator console with # IP address of 192.0.2.1 to the Cisco NBM # # Change 192.0.2.1 to match IP address used by your operators console. iptables -I INPUT 1 --source 192.0.2.1 -j ACCEPT # Repeat the previous command if you have more than one operator console. # Increment the number after the "INPUT" keyword for each console you # are adding. # # This command will allow second operator console with IP address # of 192.0.2.2 to access the Cisco NBM iptables -I INPUT 2 --source 192.0.2.2 -j ACCEPT When applying rules form the above example care must be taken to allow access to ports or protocols that are used by sensors and other devices deployed in the system that are monitored and controlled by the Cisco Network Building Mediator. Failure to do so will break connectivity to these sensors and devices. Additional mitigation techniques that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory: http://www.cisco.com/warp/public/707/cisco-amb-20100526-mediator.shtml Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities.
