  Content Service Switch Web Management HTTP Processing Vulnerabilities
------------------------------------------------------------------------

SUMMARY

The Cisco Content Service Switch (CSS) 11000 series switches are
susceptible to a soft reset caused by improper handling of HTTP POST
requests to the web management interface.

These vulnerabilities are documented as Cisco bug ID's CSCdx41911 and
CSCdw26696.

DETAILS

Affected Products:
The CSS 11000 series switches (formerly known as Arrowpoint), consist of
the CSS 11050, CSS 11150 and CSS 11800 hardware platforms. They run the
Cisco WebNS Software.

All CSS 11000 series switches running the following WebNS software
revisions are affected by these vulnerabilities.

 * 04.01.053s and earlier
 * 05.00.038s and earlier
 * 05.01.012s and earlier
 * 05.02.005s and earlier

The CSS 11500 Series switches running the following WebNS software
revisions are affected by these vulnerabilities:

 * 05.10.0.01

No other Cisco product is currently known to be affected by these
vulnerabilities.

To determine your software revision, type version at the command line
prompt on your Content Service Switch.

Details:
CSCdw26696
The CSS formerly used TCP port 8081 for its web management interface. The
web server that listens on port 8081 did not understand XML data and in
trying to process the incoming request would result in a soft reset of the
device. Currently all web management interface traffic should be directed
over SSL or "https".
 
CSCdx41911
The CSS may be forced to reboot by sending an HTTPS post request to the
web management interface of the device. This may occur even if the sender
of the request is not yet authenticated to the device.

Impact:
Both defects may reboot the device resulting in a Denial of Service (DoS)
due to decreased availability.

Software Versions and Fixes:
Cisco WebNS Software

Version Affected - Fixed Regular Release. Fix carries forward into all
later versions.
4.01 - 5.00.045 (available 2002/06/04)
5.0 - 5.00.045 (available 2002/06/04)
5.01 - 5.03
5.02 - 5.03
5.10 - TBD

Obtaining Fixed Software:
Cisco is offering free software upgrades to address this vulnerability for
all affected customers. Customers may only install and expect support for
the feature sets they have purchased.

Customers with service contracts should contact their regular update
channels to obtain any software release containing the feature sets they
have purchased. For most customers with service contracts, this means that
upgrades should be obtained through the Software Center on Cisco's
Worldwide Web site at <http://www.cisco.com> http://www.cisco.com.

Customers whose Cisco products are provided or maintained through a prior
or existing agreement with third-party support organizations such as Cisco
Partners, authorized resellers, or service providers should contact that
support organization for assistance with obtaining the free software
upgrade(s).

Customers who purchased directly from Cisco but who do not hold a Cisco
service contract, and customers who purchase through third party vendors
but are unsuccessful at obtaining fixed software through their point of
sale, should obtain fixed software by contacting the Cisco Technical
Assistance Center (TAC) using the contact information listed below. In
these cases, customers are entitled to obtain an upgrade to a later
version of the same release or as indicated by the applicable row in the
Software Versions and Fixes table (noted above).

Cisco TAC contacts are as follows:
 * +1 800 553 2447 (toll free from within North America)
 * +1 408 526 7209 (toll call from anywhere in the world)

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml for additional
TAC contact information, including special localized telephone numbers and
instructions and e-mail addresses for use in various languages.

Please have your product serial number available and give the URL of this
notice as evidence of your entitlement to a free upgrade.

Please do not contact either "psirt@cisco.com" or
"security-alert@cisco.com" for software upgrades.

Workarounds:
