Release Notes for Cisco BBSM 5.1 Microsoft Data Access Components Buffer Overrun Patch
These release notes describe the Cisco Building Broadband Service Manager (BBSM) 5.1 Microsoft Data Access Components (MDAC) Buffer Overrun patch (MDACBufferOverrun.exe), which is also known as Patch 5208.
Note The most current Cisco documentation for released products is available on Cisco Connection Online (CCO) at http://www.cisco.com. Online documents may contain updates and modifications made after the paper documents are printed.
The purpose of this patch is to eliminate a buffer overrun security vulnerability, which allows an attacker to compromise Microsoft Windows-based systems. MDACBufferOverrun.exe can be installed on BBSM 5.2, build 1.0 and any build of BBSM 5.1 with any level of patches applied.
It is possible that an attacker who successfully exploits this vulnerability can gain complete control over an affected system, which could include creating, modifying, or deleting data on the system, reconfiguring it, reformatting the hard drive, or running programs of the attacker's choice on it. This vulnerability poses a risk to both web servers and web clients. Microsoft recommends that all users take action immediately to ensure that their systems are protected against it.
For additional information, refer to Microsoft Security Bulletin MS02-065 at this website:
BBSM service packs and patches can be installed locally onto any BBSM server with Internet access. Alternatively, BBSM service packs and patches can also be installed onto multiple BBSM servers from another computer in a remote location.
Caution We recommend terminating all client sessions during BBSM service pack and patch upgrades and installations.
Follow these steps to install this patch onto your BBSM server:
Step 1 Using the Internet Explorer (IE) web browser, go to the Cisco BBSM 5.1 Software Download website:
Note Because of some known issues and incompatibilities with Netscape Navigator, you must use the IE browser when using the WEBpatch feature.
Step 2 Download MDACBufferOverrun.exe to a temporary location on your computer.
•For a local BBSM installation, go to Step 5.
•For a remote BBSM installation, continue with Step 3.
Step 3 In the IE browser Address field, type http://<ext_NIC_addr>:9488/www, where <ext_NIC_addr> is the external NIC address of the remote BBSM server. For example, type http://10.10.1.2:9488/www, and press Enter.
Step 4 Log on with your username and password. The remote BBSM Dashboard appears.
Note You must have administrator privileges to log on. Do not enter any information in the Domain field.
Step 5 From the BBSM Dashboard, use the WEBpatch utility to install this patch.
Note Refer to the Cisco BBSM 5.1 Software Configuration Guide for instructions on installing and transferring BBSM patches. After you install the patch, wait for the BBSM server to reboot.

Technical Assistance Center
The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.
Cisco TAC inquiries are categorized according to the urgency of the issue:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.
The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.
Cisco TAC Web Site
You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:
All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:
If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:
Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
