-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS Secure Copy Authorization Bypass Vulnerability Advisory ID: cisco-sa-20070808-scp http://www.cisco.com/warp/public/707/cisco-sa-20070808-scp.shtml Revision 1.0 For Public Release 2007 August 08 1600 UTC (GMT) - ----------------------------------------------------------------------- Summary ======= The server side of the Secure Copy (SCP) implementation in Cisco Internetwork Operating System (IOS) contains a vulnerability that allows any valid user, regardless of privilege level, to transfer files to and from an IOS device that is configured to be a Secure Copy server. This vulnerability could allow valid users to retrieve or write to any file on the device's filesystem, including the device's saved configuration. This configuration file may include passwords or other sensitive information. The IOS Secure Copy Server is an optional service that is disabled by default. Devices that are not specifically configured to enable the IOS Secure Copy Server service are not affected by this vulnerability. This vulnerability does not apply to the IOS Secure Copy Client feature. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20070808-scp.shtml. Note: The August 08, 2007 publication includes four Security Advisories and one Security Response. The advisories all affect IOS, one additionally affects Cisco Unified Communications Manager as well. Each advisory lists the releases that correct the vulnerability described in the advisory, and the advisories also detail the releases that correct the vulnerabilities in all four advisories. Individual publication links are listed below: * Cisco IOS Information Leakage Using IPv6 Routing Header http://www.cisco.com/warp/public/707/cisco-sa-20070808-IOS-IPv6-leak.shtml * Cisco IOS Next Hop Resolution Protocol Vulnerability http://www.cisco.com/warp/public/707/cisco-sa-20070808-nhrp.shtml * Cisco IOS Secure Copy Authorization Bypass Vulnerability http://www.cisco.com/warp/public/707/cisco-sa-20070808-scp.shtml * Voice Vulnerabilities in Cisco IOS and Cisco Unified Communications Manager http://www.cisco.com/warp/public/707/cisco-sa-20070808-IOS-voice.shtml * Cisco Unified MeetingPlace XSS Vulnerability http://www.cisco.com/warp/public/707/cisco-sr-20070808-mp.shtml Affected Products ================= Vulnerable Products +------------------ Cisco devices running certain 12.2-based IOS releases and configured to offer Secure Copy server functionality are affected by this issue. A device running a vulnerable Cisco IOS 12.2-based is affected if the following command is present in the device configuration: ip scp server enable The IOS Secure Copy server is disabled by default. The Secure Copy server functionality is only available on encryption-capable images. Devices that do not run an encryption-capable images, which contain either k8 or k9 in the image name, are not vulnerable. If a device is running an encryption-capable image, the existence of the "ip scp server enable" command in the configuration will determine whether the device is affected. Please consult the table of fixed software in the Software Version and Fixes section for the specific 12.2-based IOS releases that are affected. To determine the software running on a Cisco product, log in to the device and issue the "show version" command to display the system banner. Cisco IOS software will identify itself as "Internetwork Operating System Software" or simply "IOS". The image name will be displayed between parentheses on the next line of output followed by "Version" and IOS release name. Other Cisco devices will not have the "show version" command or will give different output. The following example identifies a Cisco product running IOS release 12.2(18)SXF10: Cisco Internetwork Operating System Software IOS (tm) s72033_rp Software (s72033_rp-IPSERVICESK9-M), Version 12.2(18)SXF10, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2007 by cisco Systems, Inc. Compiled Fri 13-Jul-07 08:32 by kellythw Additional information about Cisco IOS release naming is available at http://www.cisco.com/warp/public/620/1.html. Products Confirmed Not Vulnerable +-------------------------------- Cisco devices that do not run IOS are not affected. Cisco IOS devices that do not have the Secure Copy server feature enabled are not affected. The following IOS release trains are not affected: * 12.0-based releases * 12.1-based releases * 12.3-based releases * 12.4-based releases Cisco IOS XR is not affected. No other Cisco devices are known to be affected. Details ======= Secure Copy (SCP) is a protocol similar to the Remote Copy (RCP) protocol, which allows for the transfer of files between systems. The main difference between SCP and RCP is that in SCP, all aspects of the file transfer session, including authentication, occur in encrypted form, which makes SCP a more secure alternative than RCP. SCP relies on the Secure Shell (SSH) protocol, which uses TCP port 22 by default. The server side of the Secure Copy implementation in Cisco IOS contains a vulnerability that allows any valid user, regardless of privilege level, to transfer files to and from an IOS device that is configured to be a Secure Copy server. This vulnerability could allow valid users to retrieve or write to any file on the device's filesystem, including the device's saved configuration. This configuration file may include passwords or other sensitive information. This vulnerability does not allow for authentication bypass; login credentials are verified and access is only granted if a valid username and password is provided. This vulnerability may cause authorization to be bypassed. A device with the Secure Copy server enabled is vulnerable regardless of whether Authentication, Authorization, and Accounting (AAA) is enabled. If access control is enabled on the Virtual Terminal (vty) via the "login" command, which allows logins via Virtual Terminals, then the device is affected. This vulnerability is documented in Cisco Bug ID CSCsc19259. Vulnerability Scoring Details +---------------------------- Cisco is providing 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 1.0. Cisco will provide a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco PSIRT will set the bias in all cases to normal. Customers are encouraged to apply the bias parameter when determining the environmental impact of a particular vulnerability. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. 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. CSCsc19259 - "All privilege level users can SCP running config" CVSS Base Score - 6.0 Access Vector - Remote Access Complexity - Low Authentication - Required Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete Impact Bias - Normal CVSS Temporal Score - 5.0 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerability described in this advisory may allow valid but unauthorized users to retrieve or write to any file on the device's filesystem, including the device's saved configuration. This configuration file may include passwords or other sensitive information. 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.

+-------------------------------------------------------------+ Workarounds =========== If the IOS Secure Copy Server functionality is not needed then the vulnerability described in this document can be mitigated by disabling the Secure Copy server. The Secure Copy server can be disabled by executing the following command in global configuration mode: no ip scp server enable If the Secure Copy server cannot be disabled due to operational concerns, then no workarounds exist. The risk posed by this vulnerability can be mitigated by following the best practices detailed in "Improving Security on Cisco Routers" at http://www.cisco.com/warp/public/707/21.html. Please refer to the Obtaining Fixed Software section for appropriate solutions to resolve this vulnerability. Due to the nature of this vulnerability, networking best practices like access control lists (ACLs) and Control Plane Policing (CoPP) that restrict access to a device to certain IP addresses or subnetworks may not be effective. If access is already granted to a specific IP address or subnetwork, a user with low privileges will be able to establish a Secure Copy session with the device, which would allow the user to exploit this vulnerability. Obtaining Fixed Software ======================== Cisco will make free software available to address this vulnerability for affected customers. This advisory will be updated as fixed software becomes available. 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/public/sw-license-agreement.html, or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml. Do not contact either "psirt@cisco.com" or "security-alert@cisco.com" for 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 agreement 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 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 get their upgrades by contacting the Cisco Technical Assistance Center (TAC). 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) * e-mail: tac@cisco.com Have your product serial number available and give the URL of this notice as evidence of your entitlement to a free upgrade.
