Updated: June 27, Also, if you ever ran an earlier ASA version that had a vulnerable configuration, then regardless of the version you are currently running, you should verify that the portal customization was not compromised.

If an attacker compromised a customization object in the past, then the compromised object stays persistent after you upgrade the ASA to a fixed version. Upgrading the ASA prevents this vulnerability from being exploited further, but it will not modify any customization objects that were already compromised and are still present on the system. Configuration Migration for Transparent Mode—In 8.

Once the upgrade is complete, verify that traffic passes, and also reboot the PIX once to verify it comes back up without issue. This vulnerability is experienced in very rare occasions and extremely hard to reproduce. You can trace the lifespan of a packet through the security appliance to see whether the packet is operating correctly with the packet tracer tool.

The packet-tracer command provides detailed information about the packets and how they are processed by the security appliance. If a command from the configuration did not cause the packet to drop, the packet-tracer command will provide information about the cause in an easily readable manner.

You can use this feature to see if the implicit deny on an ACL is not taking effect. These vulnerabilities and their respective workarounds are independent of each other. The override account feature is enabled with the override-account-disable command in tunnel-group general-attributes configuration mode. As a workaround, disable this feature using the no override-account-disable command.

The following example, shows how a trusted host with IP address Temporarily disabling the feature will mitigate this vulnerability. As a workaround, remove the access-group line applied on the interface where the ACL is configured and re-apply it. For example:. In the previous example the access group called acl-inside is removed and reapplied to the inside interface. Alternatively, you can add an explicit deny ip any any line in the bottom of the ACL applied on that interface.

In the previous example, an explicit deny for all IP traffic is added at the end of access-list 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.

The following table contains the first fixed software release of each vulnerability. The "Recommended Release" row indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory.

The file contains a PDF file of the user documentation, a Bourne shell script that can be used to launch the application, and an executable JAR file.

If you must convert the outbound and conduit commands on a Linux or Macintosh workstation, you must use the Output Interpreter. See Converting the conduit and outbound Commands. Step 1 Download the occ Step 2 Unpack the archive to the desired location on your system. Convert the PIX conduit and outbound commands. Optional Configure LAN-based failover if converting from a serial cable failover configuration.

Retrieve the PIX configuration from the source device, and store it on your local file system. You can retrieve a PIX configuration in the following ways:. These commands transfer information in cleartext. Do not use them over insecure networks.

Note The conversion process does not modify the configuration on the source device. The source device can remain in operation on your network while you convert the configuration and apply the configuration to the target device.

Do not use the show config , show running-config , or show running-config all commands to retrieve the configuration. Using those commands may also display the configuration with unwanted line wrapping or the MORE prompt embedded in the output, both of which can introduce errors in the converted configuration. The recommended method for converting conduit and outbound commands is to use the OCC tool.

To convert conduit and outbound commands on Linux or Macintosh, you must use the online Output Interpreter tool. Note Using the Output Interpreter requires you to upload your configuration to a Cisco server. A conduit permits connections from one network interface to access hosts on another. The OCC tool checks for overlaps between the global address of the conduit and each of the following:. Note When a nat 0 command exists on an interface, any conduits matching the nat 0 are converted to ACL entries.

These ACL entries are then applied to all interfaces that have a lower security level, unless a global or static command matches the local addresses in the nat 0 or nat 0 access-list command or it can be determined from the available routing information that the traffic belongs to a particular interface. Note When dhcp setroute or pppoe setroute is applied to the outside interface, a default route to the outside interface is added to the routing information.

An outbound list is based on the source IP address, the destination IP address, and the destination port or protocol, as specified by the access rules. Outbound lists control Internet use by specifying the following:.

The PIX security appliance uses an algorithm to determine which outbound command to apply to a given incoming packet. The OCC tool considers an outbound command with a narrower address mask to be a better match, regardless of the service.

If the address masks are equal, a more specific service is a better match. To convert conduit and outbound commands using the OCC tool, perform the following steps:. Step 1 Open a command prompt Windows or xterm Solaris window. Step 2 Change directory to the path from which you extracted the OCC tool. Step 3 Enter the following command:. The tool creates a new configuration file with the outbound and conduit commands converted to the appropriate ACL configurations.

Use this new configuration file for the rest of the conversion process. The CLI enables the same capabilities, but it gives administrators the ability to create scripts to easily perform bulk migrations. This tool helps to expedite the migration process and to prevent administrators from making common mistakes when performing manual migrations.

Unlike the command line tool, all GUI interface configuration input and output occurs through files, rather than process standard input, output, and error output. Step 1 Launch the GUI:. Step 2 Specify the location of the input and output files. See Figure 1.

Click the Select source button to choose the source PIX configuration file, or type the full path to the file in the source field. After a source configuration file is specified, the content of the file is scanned. Note If you change the source configuration file, you must click the Rescan source configuration button so that the new file is scanned. Click the Select target button to choose the target device configuration filename or directory. Use a different filename for the target from the source.

When specifying a folder for the target location, the filename of the converted configuration will be the same as the source filename unless it resides in the same folder as the source file. In that case, an error message will be shown. After a target is specified, the target filename is verified to be different from the source name.

Note The Allow overwriting target configuration file check box allows the target configuration file to be overwritten if it exists. This check box is disabled by default to prevent the overwriting of an existing target file. If the results of the source configuration file scan contain warnings for unsupported commands, you are not permitted to proceed unless you check the Allow unsupported apply, conduit, and outbound commands button.

Step 3 Specify a target device type from the list box. See Figure 2. Target device types are specified because of the differences in the number of available interfaces. Step 4 Select the interface modules or cards that are installed in each slot. See Figure 3. For each available slot of the device type, the potential interface card names are listed, if any. Cards without external interfaces are not listed.

Note You cannot configure interface cards for certain devices that do not apply. The Cisco ASA has a slot, but no card. The Cisco ASA has a card, but it cannot be changed. Step 5 Specify interface mappings. See Figure 4. Each interface found in the source configuration file is shown with a drop-down list of the target device type interfaces and its interface cards in slots.

An attempt is made to match the fastest source interfaces with the fastest target interfaces in the expected order by listing the potentially fastest interfaces with the lowest port number first. Except for the Cisco ASA , which may be specified only with Management interfaces, Management interfaces are not initially selected because they are not intended for ordinary use for through-the-box traffic.

If the target device does not have enough interfaces to be matched uniquely with source interfaces, any remaining source interfaces are mapped to the last acceptable target interface. In this case, you must explicitly specify which source interfaces will map to either a Management interface or to no target interface.

To avoid possible misconfiguration, an alert appears for duplicate mappings. See Figure 5. Even through the configuration file may not specify a boot image, the ASA ROM configuration may specify a boot image from a previous write memory operation. If the ASA configuration specifies no boot images, the first image found is used while reloading. The log file appears. Note If this is your first conversion, all of the buttons might not be available for you to select.

The View target configuration and View log buttons are available only when the corresponding file exists. Upon your first conversion the buttons are enabled if the files already exist; however, all buttons should be available upon subsequent conversions. See Figure 6. During the conversion a status bar shows the percentage of the configuration that has completed. When conversion has finished, a message appears to inform you that the conversion has completed or has failed with an exception.

If the conversion fails, the exception information is appended to the log. You can view the source configuration, target configuration, and log files if they exist. When the viewing files are opened or reopened, the contents are refreshed from the corresponding file. If you want to convert more than one source configuration file during a session, return to the step that specifies the source file and input a new file.

To migrate a PIX security appliance to an ASA security appliance using the command line interface, use the following command at the command prompt:. If the path contains spaces, enclose the path name in double quotation marks ". Specifies that your source PIX configuration is 7. This information is useful when only interface mapping conversion is necessary.

Specifies the output file to which the converted output is saved. If the output files already exists, it will be overwritten. Specifies the log file to which errors and warnings are redirected. Warnings are generated as inline comments in the converted configuration, as well as in the log file, if specified, for example, if a feature in not supported on the new platform or if functionality has been retired.

This security advisory outlines the details of these vulnerabilities:. The following is a list of the products affected by each vulnerability as described in detail within this advisory. This feature is disabled by default. Only Cisco ASA software versions 8. Customers who use Cisco ASDM to manage their devices can find the software version displayed in the table in the login window or in the upper left corner of the ASDM window. No other Cisco products are currently known to be affected by these vulnerabilities.

This Security Advisory describes multiple distinct vulnerabilities. These vulnerabilities are independent of each other. However, the user must provide the correct credentials in order to login to the VPN. The override account feature is enabled with the override-account-disable command in tunnel-group general-attributes configuration mode, as shown in the following example.

This vulnerability can also be triggered to any interface where ASDM access is enabled. A successful attack may result in a reload of the device. A TCP three-way handshake is needed to exploit this vulnerability. A successful attack may result in a sustained DoS condition.

A Cisco ASA device configured for any of the following features is affected:. Note: This vulnerability may be triggered when crafted packets are sent to any TCP based service that terminates on the affected device. The vulnerability may also be triggered via transient traffic only if the TCP intercept features has been enabled.

A TCP three-way handshake is not needed to exploit this vulnerability. A crafted H. The requirement of a TCP three way handshake significantly reduces the possibility of exploitation using packets with spoofed source addresses. This implicit deny is there by design, does not require any configuration and can be understood as an implicit ACE that denies all traffic reaching the end of the ACL. Note: This behavior only impacts the implicit deny statement on any ACL applied on the device.

Access control lists with explicit deny statements are not affected by this vulnerability. This vulnerability is experienced in very rare occasions and extremely hard to reproduce. You can trace the lifespan of a packet through the security appliance to see whether the packet is operating correctly with the packet tracer tool. The packet-tracer command provides detailed information about the packets and how they are processed by the security appliance. If a command from the configuration did not cause the packet to drop, the packet-tracer command will provide information about the cause in an easily readable manner.

You can use this feature to see if the implicit deny on an ACL is not taking effect. These vulnerabilities and their respective workarounds are independent of each other. The override account feature is enabled with the override-account-disable command in tunnel-group general-attributes configuration mode. As a workaround, disable this feature using the no override-account-disable command.

The following example, shows how a trusted host with IP address Temporarily disabling the feature will mitigate this vulnerability. As a workaround, remove the access-group line applied on the interface where the ACL is configured and re-apply it. For example:. In the previous example the access group called acl-inside is removed and reapplied to the inside interface.
