The following sections list the new hardware and software features supported by the Cisco 1400 series for Release 12.0 T:
The following new software enhancements are supported by the Cisco 1400 series for Release 12.0(7)T and later releases.
One new feature set has been created for the Cisco 1400 series in Release 12.0(7)T:
Multicast Source Discovery Protocol (MSDP) connects multiple PIM sparse-mode (SM) domains. MSDP allows multicast sources for a group to be known to all rendezvous points (RPs) in different domains. Each PIM-SM domain uses its own RPs and need not depend on RPs in other domains. An RP runs MSDP over TCP to discover multicast sources in other domains.
An RP in a PIM-SM domain has an MSDP peering relationship with MSDP-enabled routers in another domain. The peering relationship occurs over a TCP connection, where primarily a list of sources sending to multicast groups is exchanged. The TCP connections between RPs are achieved by the underlying routing system. The receiving RP uses the source lists to establish a source path.
The purpose of this topology is to have domains discover multicast sources in other domains. If the multicast sources are of interest to a domain that has receivers, multicast data is delivered over the normal, source-tree building mechanism in PIM-SM.
MSDP is also used to announce sources sending to a group. These announcements must originate at the domain's RP.
MSDP depends heavily on (M)BGP for interdomain operation. You should run MSDP in your domain's RPs that act as sources, sending to global groups for announcement to the Internet.
The following new hardware enhancements are supported by the Cisco 1400 series for Release 12.0(5)T and later releases.
The Cisco 1417 is one in a family of low-end routers providing Ethernet-based CPE devices with an ADSL link to a telco Central Office. It is designed to provide high speed WAN access over regular copper phone lines for small remote branch offices or home offices; it provides data communications services for one or more Ethernet nodes, while at the same time allowing voice communications to a telephone. The Cisco 1417 is the second of the Cisco 1400 family of CPE routers. It is based on the Cisco 1401 1E1ATM25, and incorporates the ADSL interface using an Alcatel chip set.
There are no new features supported by the Cisco 1400 series in Cisco IOS Release 12.0(4)T.
The following new software enhancement is supported by the Cisco 1400 series for Release 12.0(3)T and later releases.
The following feature set is now available for the Cisco 1400 series in Release 12.0(3)T:
|
Note This feature set is available for the Cisco 1401 router beginning in Release 12.0(2)T. |
The following new software enhancement is supported by the Cisco 1401 router for Release 12.0(2)T and later releases.
One new feature set is now available for the Cisco 1401 router only in Release 12.0(2)T and later releases:
There are no new features supported by the Cisco 1400 series in Cisco IOS Release 12.0(1)T.
The following sections contain important notes about Cisco IOS Release 12.0 that can apply to the Cisco 1400 series.
Cisco IOS Release 12.0(6)T has been renamed 12.0(7)T to align this release with the 12.0(7) mainline release. The closed caveats for Release 12.0(7)T are identical to the caveats closed in the 12.0(7) mainline release. There was no change in the feature content of the renamed release--the features in 12.0(6)T are the same as 12.0(7)T. Release 12.0(7)T is the last maintenance release of the 12.0 T release train.
Customers needing closure of caveats for the 12.0 T features should migrate to the 12.1mainline release, which has the complete feature content of Release 12.0 T and will eventually reach General Deployment (GD). Release 12.0 T is a super set of the 12.0 mainline release, so all caveats closed in the 12.0 mainline are also closed in 12.0 T.
Certain versions of Cisco IOS software may fail or hang 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 have been observed to hang instead of failing when attacked. These devices do not recover until they are manually restarted by reset or power cycling. An administrator must personally visit an attacked, hung 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 may indicate that they were "restarted by power-on," even when that is not the case.
Assume that any potential attacker is likely to know that 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:
Vulnerable devices and software versions are specified in Table 4, Affected and Repaired Software Versions. 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 4. Cisco is correcting the problem in certain special releases and will correct it in future maintenance and interim releases. See Table 4, Affected and Repaired Software Versions for details. Cisco intends to provide fixes for all affected IOS variants.
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 issue the show version command. Cisco IOS software will identify itself simply as "IOS" or "Internetwork Operating System Software". Other Cisco devices will not have the show version command, or they will 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.
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 4 gives Cisco's projected fix dates.
Make sure 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 (say, from 11.2[11]P to 11.2[17]P), but it is often a factor when you upgrade between major releases (say, from 11.2 P to 11.3 T).
Because fixes will be available for all affected releases, this vulnerability will rarely, if ever, require an upgrade to a new major release. Cisco recommends very careful planning 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:
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 obtain only the bug fixes; free upgrades are restricted to the minimum upgrade required to resolve the defects. In general, you will be restricted to upgrading within a single row of Table 4, 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. Non-contract customers must request free updates through the TAC. Please do not contact either "psirt@cisco.com" or "security-alert@cisco.com" for software updates.
You can work around this vulnerability by preventing any affected Cisco IOS device from receiving or processing UDP datagrams addressed to its port 514. This can be done 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 that list to all interfaces to which attackers may be able to send datagrams. Interfaces include--not only physical LAN and WAN interfaces--but 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 is of interest.
No single input access list works in all configurations. 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 vulnerability:
! 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 do the detailed filtering. Because input access lists impact system performance, install them with caution--especially on systems running very near their capacity.
Many Cisco software images have been or will be specially reissued to correct this vulnerability. For example, regular released version 12.0(2) is vulnerable, as are interim versions 12.0(2.1) through 12.0(2.3). The first fixed interim version of 12.0 mainline software is 12.0(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 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 12.0(2a). Release 12.0(2a) is a "code branch" from the 12.0(2) base, which will merge back into the 12.0 mainline at 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 from12.0(2a) is to 12.0(3).

When using a multipartition flash card, the various flash partitions are referred to as "flash:1:", "flash:2:", etc. If you specify only "flash" in a multipartition flash, the parser assumes "flash:1:." For example, if you enter show flash all the parser defaults to "show flash:1: all" and only the flash information for the first partition displays. To see information for all flash partitions, enter show flash ?. This will list all of the valid partitions. Then enter show flash:xx: all on each valid partition.
On the ATM25 interface of the Cisco 1400 series there are two types of traffic shaping: hardware-based and software-based. Hardware-based traffic shaping is provided by the ATM SAR chip and is enabled on a per-pvc basis by one of the following IOS PVC configuration commands:
ubr <peak-cell-rate>
ubr+ <peak-cell-rate> <minimum-guaranteed-cell-rate>
vbr-nrt <peak-cell-rate> <sustainable-cell-rate> <maximum-burst-size>
The SAR chip has "rate counters" that control the rate at which the current buffer up for segmentation is going to be transmitted. Ideally, the SAR chip could be programmed with values for all of the above command parameters. Unfortunately, it only has the rate counters, which specify a divisor of the basic line rate of 25 Mbps and which really sets the maximum transmission rate (peak-cell-rate) for the channel. Note that with the ubr and ubr+ commands, the rate counter for the PVC is obtained from the <peak-cell-rate> parameter. With the vbr-nrt command, the rate counter is obtained from the <sustainable-cell-rate> parameter. While the <minimum-guaranteed-cell-rate> parameter in the ubr+ command and the <peak-cell-rate> parameter in the vbr-nrt command can be specified by the user, they are ignored by the ATM25 driver.
Software-based traffic shaping is enabled on a per-interface basis via the traffic-shape interface configuration command. For performance reasons, and since for ATM interfaces you most likely want to do shaping on a per-pvc basis, the ATM driver does not support software-based traffic shaping while fastswitching. However, if fast-switching is disabled and the traffic-shape interface configuration command is enabled, then software traffic shaping will occur. (See CSCdk28377 for more information.)
Cisco IOS Release 12.0(4)XI was deferred to Release 12.0(4)XI1 on all software images for the Cisco 1417, uBR7200, and uBR924.
For the Cisco 1417 router, the IP/IPX/FW Plus feature set, c1400-nosy-mz, was deferred due to the firewall not working. This image is now available in Release 12.0(5)T.
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 T are also in Release 12.0.
