Document ID: 107408


Advisory ID: cisco-sa-20080610-snmpv3

http://www.cisco.com/warp/public/707/cisco-sa-20080610-snmpv3.shtml

Revision 1.4

Last Updated 2009 January 08 1930 UTC (GMT)

For Public Release 2008 June 10 1600 UTC (GMT)

Summary

Multiple Cisco products contain either of two authentication vulnerabilities in the Simple Network Management Protocol version 3 (SNMPv3) feature. These vulnerabilities can be exploited when processing a malformed SNMPv3 message. These vulnerabilities could allow the disclosure of network information or may enable an attacker to perform configuration changes to vulnerable devices. The SNMP server is an optional service that is disabled by default in Cisco products. Only SNMPv3 is impacted by these vulnerabilities. Workarounds are available for mitigating the impact of the vulnerabilities described in this document.

Note:  SNMP versions 1, 2 and 2c are not impacted by these vulnerabilities.

The United States Computer Emergency Response Team (US-CERT) has assigned Vulnerability Note VU#878044 leavingcisco.com to these vulnerabilities.

Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-0960 leavingcisco.com has also been assigned to these vulnerabilities.

This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080610-snmpv3.shtml.

Affected Products

Vulnerable Products

The following Cisco products are vulnerable.

  • Cisco IOS
  • Cisco IOS-XR
  • Cisco Catalyst Operating System (CatOS)
  • Cisco NX-OS
  • Cisco Application Control Engine (ACE) Module
  • Cisco ACE Appliance
  • Cisco ACE XML Gateway
  • Cisco MDS 9000 Series Multilayer Fabric Switches
  • Cisco Wireless LAN Controller (WLC)
  • Cisco Application and Content Networking System (ACNS)
  • Cisco Wide Area Application Services (WAAS)

Note:  The SNMP server is disabled by default. These vulnerabilities only impact devices that are configured for SNMPv3.

To determine the version of SNMP configured in Cisco IOS, CatOS and IOS-XR, log in to the device and issue the show snmp group command. The security model field indicates the version of SNMP configured. The output "usm" is the abbreviation for user-based security model and this indicates SNMPv3 is configured.

Cisco IOS

Cisco CatOS

IronPort

IronPort C-Series, X-Series, and M-Series appliances utilize code covered by this advisory, but are not susceptible to any security risk. IronPort C-Series, X-Series, and M-Series incorporate the libraries under the advisory to provide anonymous read-only access to system health data. There is no risk of escalated authorization privileges allowing a 3rd party to make any configuration changes to the IronPort devices. IronPort S-Series and Encryption Appliances are not affected by this advisory. This announcement has also been posted on the IronPort Support Portal, available to IronPort customers: https://supportportal.ironport.com/irppcnctr/srvcd?u=http://secure-support.soma.ironport.com/announcement&sid=900016 leavingcisco.com

Products Confirmed Not Vulnerable

The following Cisco products are confirmed not vulnerable:

  • Cisco PIX Security Appliances
  • Cisco ASA Security Appliances
  • Cisco Firewall Services Module (FWSM)
  • Cisco Security Monitoring, Analysis, and Response System (MARS)
  • Cisco Network Admission Control (NAC) Appliance
  • CiscoWorks Wireless LAN Solution Engine (WLSE)

No other Cisco products are currently known to be affected by these vulnerabilities.

Details

SNMP defines a standard mechanism for remote management and monitoring of devices in an Internet Protocol (IP) network.

There are three general types of SNMP operations: "get" requests to request information, "set" requests that modify the configuration of a remote device, and "trap" messages that provide a monitoring function. SNMP requests and traps are transported over User Datagram Protocol (UDP) and are received at the assigned destination port numbers 161 and 162, respectively.

SNMPv3 provides secure access to devices by authenticating and encrypting packets over the network. RFC2574 leavingcisco.com defines the use of HMAC-MD5-96 and HMAC-SHA-96 as the possible authentication protocols for SNMPv3.

Vulnerabilities have been identified in the authentication code of multiple SNMPv3 implementations. This advisory identifies two vulnerabilities that are almost identical. Both are specifically related to malformed SNMPv3 packets that manipulate the Hash Message Authentication Code (HMAC). The two vulnerabilities may impact both Secure Hashing Algorithm-1 (SHA-1) and Message-Digest Algorithm 5 (MD5). The vulnerabilities described in this document can be successfully exploited using spoofed SNMPv3 packets.

These vulnerabilities are documented in the following Cisco Bug IDs:

Note:  Although multiple software defects are listed, this advisory only identifies two vulnerabilities. Because different Cisco products require their own fixes, additional Bug IDs have been assigned.

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.

Impact

Successful exploitation of these vulnerabilities could result in the disclosure of sensitive information on a device or allow an attacker to make configuration changes to a vulnerable device that is based on the SNMP configuration.

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.

Each row of the Cisco IOS software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table.
