New and Changed Information
The following sections list the new hardware and software features supported by the Cisco 4000 series for Release 12.0(15).
New Hardware Features in Release 12.0(15)
There are no new hardware features supported by the Cisco 4000 series in Cisco IOS Release 12.0(15).

There are no new software features supported by the Cisco 4000 series in Cisco IOS Release 12.0(15).
Important Notes
Caveat CSCdr91706 and IOS HTTP Vulnerability
A defect in multiple releases of Cisco IOS software will cause a Cisco router or switch to halt and reload if the IOS HTTP service is enabled, browsing to http://router-ip/anytext?/ is attempted, and the enable password is supplied when requested. This defect can be exploited to produce a denial of service (DoS) attack.
The vulnerability, identified as Cisco bug ID CSCdr91706, affects virtually all mainstream Cisco routers and switches running Cisco IOS software releases 12.0 through 12.1, inclusive. This is not the same defect as CSCdr36952.
The vulnerability has been corrected and Cisco is making fixed releases available for free to replace all affected IOS releases. Customers are urged to upgrade to releases that are not vulnerable to this defect as shown in detail below.
This vulnerability can only be exploited if the enable password is known or not set.
You are strongly encouraged to read the complete advisory, which is available at
http://www.cisco.com/warp/public/707/ioshttpserverquery-pub.shtml.
Ordering Cisco IOS Software
Beginning with Cisco IOS Release 12.0(7)XK, Cisco is changing the product numbers you use to order a specific Cisco IOS software image. In short, Cisco will remove the periods separating the release train, maintenance release, and build number. The following table provides some examples.
MIBs
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. Currently, OLD-CISCO-* MIBs are being converted into more scalable MIBs—without affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 6.
Caveats
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document.
For information on caveats in Cisco IOS Release 12.0, see Caveats for Cisco IOS Release 12.0, which lists severity 1 and 2 caveats and select severity 3 caveats for Release 12.0 and is located on CCO and the Documentation CD-ROM.
Related Documentation
The following sections describe the documentation available for the Cisco 4000 series. These documents consist of hardware and software installation guides, Cisco IOS configuration and command references, system error messages, and other documents.
Documentation is available as printed manuals or electronic documents.
Use these release notes with these documents:

Cisco IOS Software Documentation Set
The Cisco IOS software documentation set consists of the Cisco IOS configuration guides, Cisco IOS command references, and several other supporting documents, which are shipped with your order in electronic form on the Documentation CD-ROM—unless you specifically ordered the printed versions.
Documentation Modules
Each module in the Cisco IOS documentation set consists of two books: a configuration guide and a corresponding command reference. Chapters in a configuration guide describe protocols, configuration tasks, Cisco IOS software functionality, and contain comprehensive configuration examples. Chapters in a command reference provide complete command syntax information. Use each configuration guide with its corresponding command reference.
On CCO and the Documentation CD-ROM, two master hot-linked documents provide information for the Cisco IOS software documentation set.
