No other Cisco products are currently known to be affected by this
vulnerability.
CiscoWorks Common Services is a set of management services that are
shared by network management applications in a CiscoWorks solution set.
CiscoWorks Common Services provides the foundation for CiscoWorks
applications to share a common model for data storage, login, user role
definitions, access privileges, security protocols, and navigation. It creates
a standard user experience for all management functions. It also provides the
common framework for all basic system level operations such as installation,
data management (including backup-restoration and importing-exporting), event
and message handling, job and process management, and software updates.
Exploitable buffer overflows exist in the Cisco developed
authentication code in the web server module of CiscoWorks Common Services,
which can be exploited remotely without authentication.
A successful exploit could cause the web server to crash or allow the
attacker to execute arbitrary code on the server. Any code would execute with
system administrative privileges.
The vulnerability could be exploited over TCP port 443 or 1741.
Note: The default HTTP and HTTPS ports can be
reconfigured on the server.
The vulnerability affects both CiscoWorks Common Services for Oracle
Solaris and Microsoft Windows.
This vulnerability is documented in Cisco bug ID
CSCti41352
(
registered customers only)
.
This vulnerability has been assigned Common Vulnerabilities and
Exposures (CVE) ID CVE-2010-3036.
Cisco has provided scores for the vulnerability in this advisory based
on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this
Cisco Security Advisory is done in accordance with CVSS version 2.0.
CVSS is a standards-based scoring method that conveys
vulnerability severity and helps determine urgency and priority of response.
Cisco has provided a base and temporal score. Customers can
then compute environmental scores to assist in determining the impact of the
vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions
regarding CVSS at
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html .
Cisco has also provided a CVSS calculator to help compute
the environmental impact for individual networks at
http://intellishield.cisco.com/security/alertmanager/cvss .

Successful exploitation of this vulnerability could allow a remote
unauthenticated attacker to execute arbitrary code on the CiscoWorks server
machine with the privileges of the system administrator.
Cisco has released free software updates that address this
vulnerability. Prior to deploying software updates, customers should consult
their maintenance provider or check the software for feature set compatibility
and known issues specific to their environment.
This vulnerability has been resolved in CiscoWorks Common Services
version 4.0.

These CiscoWorks Common Services patches can be downloaded from
http://www.cisco.com/cisco/software/navigator.html?mdfid=268439477&i=rp.
Navigate through the tree to "Routing and Switching Management > CiscoWorks
LAN Management Solution Products > CiscoWorks Common Services Software >
CiscoWorks Common Services Software <appropriate version>." Choose
Solaris or Windows, depending on your operating system.
When considering software upgrades, also consult
http://www.cisco.com/go/psirt
and any subsequent advisories to determine exposure and a complete upgrade
solution.
In all cases, customers should exercise caution to be certain the
devices to be upgraded contain sufficient memory and that current hardware and
software configurations will continue to be supported properly by the new
release. If the information is not clear, contact the Cisco Technical
Assistance Center (TAC) or your contracted maintenance provider for assistance.
Filters such as transit access control lists (tACLs) can be used to
allow access to the Administration Workstation only from trusted hosts. This
mitigation limits the attack surface of the vulnerability.
Filters that deny HTTPS packets using TCP port 443 and TCP port 1741
should be deployed throughout the network as part of a tACL policy to protect
the network from traffic that enters at ingress access points. This policy
should be configured to protect the network device where the filter is applied
and other devices that are behind it. Filters for HTTPS packets that use TCP
port 443 and TCP port 1741 should also be deployed in front of vulnerable
network devices so that only traffic from a trusted client is allowed.
Note: Additional information about tACLs is available
in "Transit Access Control Lists: Filtering at Your Edge" at the following
link:
http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801afc76.shtml
Additional mitigations that can be deployed on Cisco devices within the
network are available in the Cisco Applied Intelligence companion document for
this Advisory:
http://tools.cisco.com/security/center/content/CiscoAppliedMitigationBulletin/cisco-amb-20101027-cs.
Cisco has released free software updates that address this
vulnerability. Prior to deploying software, customers should consult their
maintenance provider or check the software for feature set compatibility and
known issues specific to their environment.
Customers may only install and expect support for the
feature sets they have purchased. By installing, downloading, accessing or
otherwise using such software upgrades, customers agree to be bound by the
terms of Cisco's software license terms found at
http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html
, or as otherwise set forth at Cisco.com Downloads at
http://www.cisco.com/public/sw-center/sw-usingswc.shtml
.
Do not contact psirt@cisco.com or security-alert@cisco.com
for software upgrades.
Customers with contracts should obtain updated patches through their
regular update channels. For most customers, this means that patches should be
obtained through the Software Center on Cisco's worldwide website at

Customers whose Cisco products are provided or maintained through prior
or existing agreements with third-party support organizations, such as Cisco
Partners, authorized resellers, or service providers should contact that
support organization for guidance and assistance with the appropriate course of
action in regards to this advisory.
The effectiveness of any workaround or fix is dependent on
specific customer situations, such as product mix, network topology, traffic
behavior, and organizational mission. Due to the variety of affected products
and releases, customers should consult with their service provider or support
organization to ensure any applied workaround or fix is the most appropriate
for use in the intended network before it is deployed.
Customers who purchase direct from Cisco but do not hold a Cisco
service contract, and customers who purchase through third-party vendors but
are unsuccessful in obtaining fixed software through their point of sale should
acquire upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC
contacts are as follows.
