-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: A Default Username and Password in WLSE and HSE Devices Revision 1.0 Last Updated For Public Release 2004 April 07 1600 UTC (GMT) - ------------------------------------------------------------------------- Summary ======= A default username/password pair is present in all releases of the Wireless LAN Solution Engine (WLSE) and Hosting Solution Engine (HSE) software. A user who logs in using this username has complete control of the device. This username cannot be disabled. There is no workaround. This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20040407-username.shtml. Affected Products ================= * The affected software releases for WLSE are 2.0, 2.0.2 and 2.5. * The affected software releases for HSE are 1.7, 1.7.1, 1.7.2 and 1.7.3. Details ======= A hardcoded username and password pair is present in all software releases for all models of WLSE and HSE devices. This vulnerability is documented in the Cisco Bug Toolkit as Bug ID CSCsa11583 (registered customers only) for the WLSE and CSCsa11584 (registered customers only) for the HSE. CiscoWorks WLSE provides centralized management for the Cisco Wireless LAN infrastructure. It unifies the other components in the solution and actively employs them to provide continual "Air/RF" monitoring, network security, and optimization. The CiscoWorks WLSE also assists network managers by automating and simplifying mass configuration deployment, fault monitoring and alerting. Cisco Hosting Solution Engine is a hardware-based solution to monitor and activate a variety of e-business services in Cisco powered data centers. It provides fault and performance information about the Layer 2-3 hosting infrastructure and Layer 4-7 hosted services. Impact ====== Any user who logs in using this username has complete control of the device. One can add new users or modify details of the existing users, and change the device's configuration. Here are some more concrete examples of possible actions: * For WLSE this means that an adversary can hide the presence of a rogue Access Point or change the Radio Frequency plan, potentially causing system-wide outages. The first action may cause long term loss of information confidentiality and integrity. The second action can yield Denial-of-Service (DOS). * For HSE this may lead up to illegal re-directing of a Web site with the ultimate loss of revenue. * In both cases the device itself may be used as a launching platform for further attacks. Such attacks could be directed at your organization, or towards a third party. Software Versions and Fixes =========================== For WLSE, users need to install the WLSE-2.x-CSCsa11583-K9.zip patch. The patch can be downloaded from http://www.cisco.com/cgi-bin/tablebuild.pl/wlan-sol-eng (registered customers only) This patch is applicable to WLSE 1130 software releases 2.0, 2.0.2 and 2.5. For HSE, users need to install the HSE-1.7.x-CSCsa11584.zip patch. The patch can be downloaded from http://www.cisco.com/cgi-bin/tablebuild.pl/1105-host-sol (registered customers only). This patch is applicable to HSE 1105 for versions 1.7, 1.7.1, 1.7.2, and 1.7.3. Obtaining Fixed Software ======================== Customers with Service Contracts As the fix for this vulnerability is a default configuration change, and a workaround is available, a software upgrade is not required to address this vulnerability. However, if you have a service contract, and wish to upgrade to unaffected code, you may obtain upgraded software through your regular update channels once that software is available. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's Worldwide Web site at http://www.cisco.com. Customers using Third-party Support Organizations Customers whose Cisco products are provided or maintained through prior or existing agreement with third-party support organizations such as Cisco Partners, authorized resellers, or service providers should contact that support organization for assistance with the upgrade, which should be free of charge. Customers without Service Contracts Customers who purchase direct from Cisco but who do not hold a Cisco service contract and customers who purchase through third-party vendors but are unsuccessful at obtaining fixed software through their point of sale should get their upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows. * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac@cisco.com Please have your product serial number available and give the URL of this notice as evidence of your entitlement to a free upgrade. Free upgrades for non-contract customers must be requested through the TAC. Please do not contact either "psirt@cisco.com" or "security-alert@cisco.com" for software upgrades. If you need assistance with the implementation of the workarounds, or have questions on the workarounds, please contact the Cisco Technical Assistance Center (TAC). * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac@cisco.com See http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml for additional TAC contact information, including special localized telephone numbers and instructions and e-mail addresses for use in various languages. Customers may only install and expect support for the feature sets they have purchased.
