Introduction

This section contains information about the Cisco AS5300 series universal access servers and Early Deployment (ED) releases for the Cisco AS5300.

Cisco AS5300

The Cisco AS5300 series universal access servers are versatile data communications platforms. Each Cisco AS5300 provides the function of an access server, a router, and a bank of digital modems in a single modular chassis. The access server is intended for Internet service providers (ISPs), telecommunications carriers, and other service providers that offer managed Internet connections, in addition to medium to large sites that provide both digital and analog access to users on an enterprise network. By terminating both analog and digital calls on the same chassis simultaneously, the access server provides a clear, simple, and easy migration path from analog dial-access services to digital dial-access services.

For information on new features and Cisco IOS commands supported by Release 12.0 XI, refer to the "New and Changed Information" section and the "Related Documentation" section.

Early Deployment Releases

These release notes describe only Release 12.0(4)XI for Cisco AS5300 series universal access servers and do not describe features that are available in Release 12.0 or other Release 12.0 Early Deployment (ED) releases. Release 12.0 XI is an Early Deployment (ED) release based on Release 12.0 and announces fixes to software caveats and support for new Cisco hardware.

For information about features in Release 12.0, see Cross-Platform Release Notes for Cisco IOS Release 12.0  on CCO and the Documentation CD-ROM.

For information about features in other ED releases, see Table 1.

For information about features in other platforms, see Release Notes for Cisco IOS Release  12.0 on CCO  and the Documentation CD-ROM.

Determining the Version of Your Software Release

To determine the version of Cisco IOS software running on your Cisco AS5300, log in to the access server and enter the show version EXEC command.

router>show version
Cisco Internetwork Operating System Software
IOS (tm) AS5300 Software (c5300-i-mz), Version 12.0(4)XI, RELEASE SOFTWARE

Upgrading to a New Software Release

For information on upgrading to a new software release, see the product bulletin Cisco IOS Software Release  12.0 T Upgrade Paths and Packaging Simplification (#819: 1/99)   on CCO at:

Service & Support: Product Bulletins: Software

Under Cisco IOS 12.0, click Cisco IOS Software Release 12.0 T Upgrade (#819: 1/99).

Modem Code

Modem code is either stored in Flash memory or bundled in the Cisco IOS software image. Bundling eliminates the need to store separate modem code images. When the Cisco AS5300 starts, the system software unpacks the modem software bundle and loads the proper code on the modem cards.

The show modem mapping command lists all versions of modem code running on the modem modules, residing in system Flash, and bundled with Cisco IOS software. Enter the show modem mapping command to determine if you need to update your modem code files.


Note      You could have received a later version of modem code than the one bundled with the Cisco IOS software. The modem code in Flash memory is mapped to the modems. Unless you fully understand how Cisco IOS software uses modem code, it is important to keep the factory configuration.


The modem code release notes are on CCO and the Documentation CD-ROM:

You can reach the release notes on CCO at:

Service & Support: Documentation Home Page: Access Servers and Access Routers: Access Servers: Cisco AS5300: Modem Information: Firmware/Portware Release Notes

New and Changed Information

The following sections list the new hardware and software features supported by the Cisco AS5300 series universal access servers in Cisco IOS Release 12.0 XI.

New Software Features in Cisco IOS Release 12.0(4)XI

The following software features are supported by the Cisco AS5300 series universal access servers for Release 12.0(4)XI.

Resource Pool Management

The Resource Pool Manager differentiates wholesale dial customers by using configurable Customer Profiles that are based on the dialed number (DNIS) and Call Type determined at the time of an incoming call or by Domain Name after the call is answered. Each configured Customer Profile will include a maximum allowed session value and an overflow value. As sessions are started and ended in the NAS, session counters for each Customer Profile are incremented and decrements in the NAS. Based upon service-level agreements, customers will be given the appropriate call treatment when the session limit is reached.

Important Notes

The following sections contain important notes about Cisco IOS Release 12.0 that might apply to the Cisco AS5300.

Cisco IOS Syslog Failure

Certain versions of Cisco IOS software can fail when they receive invalid User Datagram Protocol (UDP) packets sent to their syslog ports (port 514). At least one commonly used Internet scanning tool generates packets that cause such problems. This fact has been published on public Internet mailing lists, which are widely read both by security professionals and by security crackers. This information should be considered in the public domain.

Attackers can cause Cisco IOS devices to repeatedly fail and reload, resulting in a completely disabled Cisco IOS device that needs to be reconfigured by its administrator. Some Cisco IOS devices can hang instead of failing when attacked. These devices do not recover until they are manually restarted by reset or power cycling. An administrator must visit the device to restart it, even if the attacker is no longer actively sending any traffic. Some devices have failed without providing stack traces; some devices indicate that they were "restarted by power-on," even when that was not the case.

Assume that any potential attacker knows the existence of this problem and the ways to exploit it. An attacker can use tools available to the public on the Internet and does not need to write any software to exploit the vulnerability. Minimal skill is required and no special equipment is required.

Despite Cisco specifically inviting such reports, Cisco has received no actual reports of malicious exploitation of this problem.

This vulnerability notice was posted on Cisco's World Wide Web site:

http://www.cisco.com/warp/public/770/iossyslog-pub.shtml

This information was also sent to the following e-mail and USENET news recipients:

Affected Devices and Software Versions

Table 6 describes hardware and software that are affected by this problem. Affected versions include Releases 11.3 AA, 11.3 DB, and all 12.0 versions (including 12.0 mainline, 12.0 S, 12.0 T, and any other regular released version whose number starts with 12.0), up to the repaired releases listed in Table 6. Cisco is correcting the problem in certain special releases, will correct it in future maintenance and interim releases, and intends to provide fixes for all affected IOS variants. See Table 6, Affected and Repaired Software Versions for details.

No particular configuration is needed to make a Cisco IOS device vulnerable. It is possible to filter out attack traffic by using access lists. See the "Workarounds" section for techniques. However, except at Internet firewalls, the appropriate filters are not common in customer configurations. Carefully evaluate your configuration before assuming that any filtering you have protects you against this attack.

The most commonly used or asked-about products are listed below. If you are unsure whether your device is running Cisco IOS software, log in to the device and enter the show version command. Cisco IOS software will identify itself simply as "IOS" or "Internetwork Operating System Software." Other Cisco devices do not have the show version command and identify themselves differently in their output. The most common Cisco devices that run Cisco IOS software include the following:

Affected software versions, which are relatively new, are not necessarily available on every device listed above. If you are not running Cisco IOS software, you are not affected by this problem.

The following Cisco devices are not affected:

This vulnerability has been assigned Cisco bug ID CSCdk77426.

Solution

Cisco offers free software updates to correct this vulnerability for all affected customers—regardless of their contract status. However, because this vulnerability information has been disseminated by third parties, Cisco has released this notice before updates are available for all software versions. Table 6 gives Cisco's projected fix dates.

Make sure that your hardware has adequate RAM to support the new software before installing it. The amount of RAM is seldom a problem when you upgrade within a major release, for example, from 11.2[11]P to 11.2[17]P, but it is often a factor when you upgrade between major releases, for example, from 11.2 P to 11.3 T.

Because fixes will be available for all affected releases, this vulnerability will rarely, if ever, require you to upgrade to a new major release. Cisco recommends that you carefully plan for any upgrade between major releases. Make certain no known bugs will prevent the new software from working properly in your environment.

Further upgrade planning assistance is available on Cisco's World Wide Web site at:

http://www.cisco.com

If you have service contracts, you can obtain new software through your regular update channels (generally through Cisco's World Wide Web site). You can upgrade to any software release, but you must remain within the boundaries of the feature sets you have purchased.

If you do not have service contracts, you can upgrade to only obtain the bug fixes; free upgrades are restricted to the minimum upgrade required to resolve the defects. You can only upgrade to the software described in one row of Table 6—except when no upgrade within the same row is available in a timely manner.

Obtain updates by contacting one of the following Cisco Technical Assistance Centers (TACs):

Give the URL of this notice (http://www.cisco.com/warp/public/770/iossyslog-pub.shtml) as evidence for a free update. Customers with no contracts must request for free updates through the TAC. For software updates, please do not contact either "psirt@cisco.com" or "security-alert@cisco.com.

Workarounds

You can work around this vulnerability by preventing any affected Cisco IOS device from receiving or processing UDP datagrams addressed to port 514. You can do this by either using packet filtering on surrounding devices, or by using input access list filtering on the affected IOS device itself.

If you use an input access list, apply it to all interfaces to which attackers can send datagrams. Interfaces include not only physical LAN and WAN interfaces but also virtual subinterfaces of those physical interfaces—as well as virtual interfaces and interface templates corresponding to GRE, L2TP, L2F, and other tunneling protocols.

The input access list must block traffic destined for UDP port 514 at any of the Cisco IOS device's own IP addresses—as well as at any broadcast or multicast addresses on which the Cisco IOS device may be listening. Be sure to block both old-style "all-zeros" broadcasts and new-style "all-ones" broadcasts. It is not necessary to block traffic being forwarded to other hosts—only traffic actually addressed to the Cisco IOS device.

No single input access list works in all configurations. Be sure you know the effect of your access list in your specific configuration before activating it.

The following example shows a possible access list for a three-interface router, along with the configuration commands needed to apply the list. The example assumes input filtering is not needed—other than as a workaround for this problem:

! Deny all multicasts, and all unspecified-net broadcasts, to port 514
access-list 101 deny udp any 224.0.0.0 31.255.255.255 eq 514
! Deny old-style unspecified-net broadcasts
access-list 101 deny udp any host 0.0.0.0 eq 514
! Deny network-specific broadcasts. This example assumes that all of
! the local interfaces are on the class B network 172.16.0.0, subnetted
! everywhere with mask 255.255.255.0. This will differ from network
! to network. Note that we block both new-style and old-style broadcasts.
access-list 101 deny udp any 172.16.0.255 0.0.255.0 eq 514
access-list 101 deny udp any 172.16.0.0 0.0.255.0 eq 514
! Deny packets sent to the addresses of our own network interfaces.
access-list 101 deny udp any host 172.16.1.1 eq 514
access-list 101 deny udp any host 172.16.2.1 eq 514
access-list 101 deny udp any host 172.16.3.3 eq 514
! Permit all other traffic (default would be to deny)
access-list 101 permit ip any any
! Apply the access list to the input side of each interface
interface ethernet 0
ip address 172.16.1.1 255.255.255.0
ip access-group 101 in
interface ethernet 2
ip address 172.16.2.1 255.255.255.0
ip access-group 101 in
interface ethernet 3
ip address 172.16.3.3 255.255.255.0
ip access-group 101 in

Listing all possible addresses—especially all possible broadcast addresses—to which attack packets can be sent is complicated. If you do not need to forward any legitimate syslog traffic received on an interface, you can block all syslog traffic arriving on that interface. Remember that blocking will affect traffic routed through the Cisco IOS device—as well as traffic destined to the device. If the IOS device is expected to forward syslog packets, you will have to filter in detail. Because input access lists impact system performance, install them with caution—especially on systems running very near their capacity.

Software Versions and Fixes

Many Cisco software images have been or will be specially reissued to correct this vulnerability. For example, regular released Cisco IOS version 12.0(2) is vulnerable, as are interim versions 12.0(2.1) to 12.0(2.3). The first fixed interim version of Release12.0 mainline software is Release12.0(2.4). However, a special release, 12.0(2a), contains only the fix for this vulnerability and does not include any other bug fixes from later 12.0 interim releases.

If you are running Release 12.0(2) and want to fix this problem without risking possible instability presented by installing the 12.0(2.4) interim release, you can upgrade to Release 12.0(2a). Release 12.0(2a) is a "code branch" from the Release 12.0(2) base, which will merge back into the Release 12.0 mainline at Release 12.0(2.4).

Special releases, like 12.0(2a), are one-time spot fixes, and they will not be maintained. Thus, the upgrade path from Release 12.0(2a) is to Release 12.0(3).

Caveats

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.

This section only contains open and resolved caveats for the current Cisco IOS maintenance release.

All caveats in Release 12.0 and Release 12.0 T are also in Release 12.0 XI.

For information on caveats in Cisco IOS Release 12.0, see Caveats for Cisco IOS Release  12.0 .

For information on caveats in Cisco IOS Release 12.0 T, see Caveats for Cisco IOS Release  12.0  T, which lists severity 1 and 2 caveats, and is located on CCO and the Documentation CD-ROM.


Note      If you have an account with CCO, you can use Bug Navigator II to find caveats of any severity for any release. You can reach Bug Navigator II on CCO at Service & Support: Online Technical Support: Software Bug Toolkit., or at http://www.cisco.com/support/bugtools.


Open Caveats—Release 12.0(4)XI

This section describes possibly unexpected behavior by Release 12.0(4)XI. Unless otherwise noted, these caveats apply to all 12.0 releases up to and including 12.0(4)XI.

Basic System Services

The following cli command does not function : snmp-server packetsize. The maximum snmp packetsize for 12.0(3)T is fixed at 484. There is no known workaround.

Miscellaneous

When tunneling IPX over an IP tunnel, and when using an extended inbound access list for ip on the tunnel interface, the ipx traffic gets blocked by the access list. As a workaround a "permit gre" statement could be added in the extended access-list.

Resolved Caveats—Release 12.0(4)XI

Because Release 12.0(4)XI is the base release, there are no resolved caveats.
