Important Notes
This section contains the following important notes about Cisco IOS Release 12.0(4)XM1 that apply to the Cisco 805 router:
•
Maximum Speed for Cisco 805 Router Synchronous Interfaces
The Cisco 805 router limits the maximum operating speed of synchronous interfaces to a maximum of 512 K in both DTE mode and DCE mode.When the Cisco 805 router is in DTE mode and the clock rate exceeds 512 K, the serial link is shut down and the following message appears on the console:
WARNING:MAXIMUM INTERFACE SPEED OF 512KB EXCEEDED SHUTTING DOWN INTERFACE.Cisco IOS Syslog Failure
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:

Affected Devices and Software Versions
Vulnerable devices and software versions are specified in , . 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 . Cisco is correcting the problem in certain special releases and will correct it in future maintenance and interim releases. See , 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.
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. 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:
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 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 , 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.
Workarounds
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 by 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 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 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 problem:
! Deny all multicasts, and all unspecified-net broadcasts, to port 514access-list 101 deny udp any 224.0.0.0 31.255.255.255 eq 514! Deny old-style unspecified-net broadcastsaccess-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 514access-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 514access-list 101 deny udp any host 172.16.2.1 eq 514access-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 interfaceinterface ethernet 0ip address 172.16.1.1 255.255.255.0ip access-group 101 ininterface ethernet 2ip address 172.16.2.1 255.255.255.0ip access-group 101 ininterface ethernet 3ip address 172.16.3.3 255.255.255.0ip access-group 101 inListing all possible addresses—especially all possible broadcast addresses—to which attack packets may 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.
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) through 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).
