Otkrivene su dvije ranjivosti u softveru CiscoWorks LAN Management Solution paketu. Riječ je o integriranom programskom skupu upravljačkih funkcija koje pojednostavljuju konfiguriranje, administriranje, nadgledanje i pronalaženje grešaka u mreži. Uzrok ranjivosti nije naveden u preporuci, no poznato je da ranjivosti omogućuju neautenticiranom udaljenom napadaču izvršavanje proizvoljnog programskog koda na pogođenim poslužiteljima. Ranjivosti mogu biti pokrenute slanjem niza posebno oblikovanih paketa prema pogođenim poslužiteljima preko TCP porta 9002. Ranjive inačice softvera su 3.1, 3.2 i 4.0, s time da su prve dvije inačice ranjive jedino ako se instalira Device Fault Management (DFM) komponenta. Korisnicima se savjetuje instalacija Cisco Prime LAN Management Solution softvera inačice 4.1, koja sadrži potrebne ispravke.

Revision 1.0
For Public Release 2011 September 14 1600 UTC (GMT)
+-----------------------------------------------------------------
Summary
=======
Two vulnerabilities exist in CiscoWorks LAN Management Solution
software that could allow an unauthenticated, remote attacker to
execute arbitrary code on affected servers.
Cisco has released free software updates that address these
vulnerabilities.
There are no workarounds available to mitigate these vulnerabilities.
This advisory is posted at:
http://www.cisco.com/warp/public/707/cisco-sa-20110914-lms.shtml
Note: Cisco Unified Service Monitor and Cisco Unified Operations
Manager are also affected by these vulnerabilities. A separate
advisory for Cisco Unified Service Monitor and Cisco Unified
Operations Manager is available at:
http://www.cisco.com/warp/public/707/cisco-sa-20110914-cusm.shtml
Affected Products
=================
Vulnerable Products
+------------------
CiscoWorks LAN Management Solution software releases 3.1, 3.2, and
4.0 are affected by this vulnerability.
Cisco LAN Management Solution versions 3.1 and 3.2 are vulnerable
only if the Device Fault Management component (DFM) is installed.
Cisco LAN Management Solution versions 4.0 and later are vulnerable
regardless of the options selected during installation.
Note: Cisco Unified Service Monitor and Cisco Unified Operations
Manager are also affected by these vulnerabilities.
Products Confirmed Not Vulnerable
+--------------------------------
No other Cisco products other than the Cisco Unified Service Monitor
and Cisco Unified Operations Manager are currently known to be
affected by these vulnerabilities.
Details
=======
CiscoWorks LAN Management Solution is an integrated suite of
management functions that simplifies the configuration,
administration, monitoring, and troubleshooting of a network.
Two vulnerabilities exist in CiscoWorks LAN Management Solution
software that could allow an unauthenticated, remote attacker to
execute arbitrary code on affected servers.
Note: These vulnerabilities can be triggered by sending a series of
crafted packets to the affected server over TCP port 9002.
Both vulnerabilities are documented in Cisco bug ID CSCtn64922 (
registered customers only) and have been assigned CVE ID
CVE-2011-2738.
Vulnerability Scoring Details
+----------------------------
Cisco has provided scores for the vulnerabilities in this advisory
based on the Common Vulnerability Scoring System (CVSS). The CVSS
scoring in this 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
* CSCtn64922 - Cisco Unified Service Monitor Remote Code Execution
CVSS Base Score - 10
Access Vector - Network
Access Complexity - Low
Authentication - None
Confidentiality Impact - Complete
Integrity Impact - Complete
Availability Impact - Complete
CVSS Temporal Score - 8.3
Exploitability - Functional
Remediation Level - Official-Fix
Report Confidence - Confirmed
Impact
======
Successful exploitation of these vulnerabilities could allow an
unauthenticated, remote attacker to execute arbitrary code on
affected servers.
Software Versions and Fixes
===========================
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.
These vulnerabilities have been corrected in Cisco Prime LAN
Management Solution Software version 4.1.
Cisco Prime LAN Management Solution Software can be downloaded from
the following link:
http://www.cisco.com/cisco/software/navigator.html?mdfid=283427841&i=rm
Workarounds
===========
There are no workarounds available to mitigate these vulnerabilities.
Additional mitigations that can be deployed on Cisco devices within
the network are available in the Cisco Applied Mitigation Bulletin
companion document for this advisory, which is available at the
following link:
http://www.cisco.com/warp/public/707/cisco-amb-201100914-cusm-lms.shtml
Obtaining Fixed Software
========================
Cisco has released free software updates that address these
vulnerabilities. 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:

software upgrades.
Customers with Service Contracts
+-------------------------------
Customers with contracts should obtain upgraded software through
their regular update channels. For most customers, this means that
upgrades should be obtained through the Software Center on Cisco's
worldwide website at http://www.cisco.com
Customers using Third Party Support Organizations
+------------------------------------------------
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 without Service Contracts
+----------------------------------
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.
* +1 800 553 2447 (toll free from within North America)
