Version 1. X releases All 5. No other Cisco products are currently known to be affected by these vulnerabilities. The issues are detailed below: CSCef -- A specifically crafted Transmission Control Protocol TCP connection may cause the ACNS cache process to restart resulting in a loss of cached information and degraded service of web browser content requests. Repeated exploitation could result in a sustained DoS attack against the caching functionality of the device. A reboot of the device is required to recover from the high CPU.

Repeated exploitation could result in a sustained DoS attack. This could result in a denial of service to the affected device and other devices on the same local network segment with the affected device. A reboot of the device is required to recover from this condition.

Repeated exploitation could result in a sustained DoS attack to all devices on the local network segment. CSCef -- The administrative password is set to a default password that is the same in all installations if the ACNS setup dialog has not been previously run or the administrative password has not been manually changed. All enabled services will use the default credential. RealServer RealSubscriber if it is running.

By default the RealServer RealSubscriber is disabled. To verify if the RealServer RealSubscriber is running, use the command show rtsp server real-subscriber. The following output shows an enabled RealServer RealSubscriber: cacheengine show rtsp server Real Subscriber version: ce Estimated 17 days 21 hours left for evaluation.

Real Subscriber license key not installed Real Subscriber bandwidth enforced is kbps To disable the RealServer RealSubscriber, use the command no rtsp server real-subscriber enable while in global configuration mode as shown below: cacheengine configure terminal cacheengine config no rtsp server real-subscriber enable cacheengine config exit The following output shows a disabled RealServer RealSubscriber: cacheengine show rtsp server real-subscriber Real Subscriber version: ce For the potential default password issue CSCef , if the setup dialog has been previously run or the administrative password previously changed the workaround is not required.

If the setup dialog has not been run or the administrative password has not been changed, the workaround is to manually change the admin account password. To change the default password, users should run the username command once they have logged in as the admin user. The following interaction shows an example of a change password dialog on a Content Engine that is performed via the console port: Username: admin Password: System Initialization Finished.

It is available on Cisco routers and firewalls. X releases Upgrade to 5. Cisco Security Vulnerability Policy. Revision 1. Show Less. Legal Disclaimer. Upgrade to 5. Step 6 Click the Edit icon next to the virtual blade that you want to configure, or click the Create button to create a new virtual blade.

The Virtual Blade configuration window appears see Figure 3. Step 7 Configure the virtual blade system parameters as follows:. If you are creating a new virtual blade, type the number of the virtual blade that you want to create in the Blade Number field.

The number of virtual blades that you can configure depends on which model of WAAS appliance you are using and the amount of memory installed in that appliance. Optional In the Description field, type a brief description of the virtual blade. Choose cd-rom the default to boot the virtual blade from a physical CD or a CD image. In the Disk Space field, allocate the amount of WAE hard disk space by specifying up to four disk values separated by a space , in gigabytes, that you want allocated for the virtual blade as shown in Figure 3 , for example.

See Table 2 for disk value descriptions. To configure a virtual blade with two disks, you must configure disk values 1 through 4. For example, the entry 2 20 0 specifies a 2-GB flash, and two disks GB disk00 and GB disk01 for the virtual blade. To create a virtual blade with a single disk, for example, configure only the first two disk values. In the Memory field, allocate the amount of WAE memory, in megabytes, that you want to make available for the virtual blade.

The amount of memory that can be allocated for a virtual blade depends on the amount of memory in your WAE or WAVE appliance, and on the amount of memory that is assigned to other virtual blades. On the CPU Emulation list, choose qemu32 for a bit processor emulator , which is the type of CPU emulation that the virtual blade uses. Step 8 Configure the interface bridge that you want to use between the virtual blade and the physical interfaces on your WAE as follows:.

In the Virtual Interfaces pane, click Add. The Virtual Interface Add pane appears see Figure 4. In the Interface Number field, enter the virtual blade interface to be bridged. Valid values are 1 or 2. In the Bridge Interface list, choose the physical WAE interface that the virtual blade interface is bridged to. Choose either GigabitEthernet or PortChannel. Click Add to List to add the virtual interface to the virtual blade interface list. Step 9 Choose the virtual interface by clicking its radio button on the display.

Step 10 Click Submit. The Virtual Blade Actions window appears see Figure 5. Step 4 In the Virtual Blade list, choose the virtual blade that you want to enable or disable. The status of the virtual blade is displayed in the Status field. The default selection for the Virtual Blade list is All. When All is selected, the Status field displays the current status for all virtual blades.

Step 5 Click Start Virtual Blade to enable the selected virtual blade. Step 6 Optional In the Startup Delay field, enter a startup delay by typing a value, in seconds. The startup delay can be used to give you time to connect a VNC session to the console before the virtual blade boots, so you can observe the initial startup. Step 7 Click Stop Virtual Blade to disable the selected virtual blade.

Step 8 Optional In the Shutdown Timeout field, enter a value, in seconds, to give the virtual blade operating system time to shut down the virtual blade after you click the Stop Virtual Blade button. The shutdown timeout provides a delay period in which the operating system can shut down gracefully. If the operating system has not shut down the virtual blade by the end of this period, WAAS forces the shutdown. To avoid losing data in open programs running on the virtual blade, it is safer to have the operating system perform the shutdown.

Step 9 Click Refresh Status to refresh the status of the virtual blade after you make a change. Note The operating system on your virtual blade does not shut down and restart when you reboot the WAAS device. Step 7 In the Remote Filename field, enter the filename of the disk image. Step 9 In the Local Filename field, enter the full path and filename where the disk image is to be stored on the WAE device.

Step 10 Click Start File Transfer to start the file transfer. Step 1 Once you have started the virtual blade, create a console session to the virtual blade to access the ACNS Installer Menu by using the following command:. Step 3 When the ACNS installation is complete, stop the virtual blade session by using the following command:.

Step 4 After the session stops, change the boot option of the virtual blade to disk by using the following commands:. Step 1 Once you have changed the boot option to disk, restart the virtual blade and then start another session to the virtual blade by using the following commands:. ACNS config cms enable. Verify that the IP address is configured, the interface is up, and the working interface is assigned as the primary interface. For example, enter this URL:.

Step 2 Click Yes to accept the security certificate.
