CVE-2011-2547

TITLE

Cisco SA 500 series security appliances Vulnerable to arbitrary command execution

DESCRIPTION

The web-based management interface on Cisco SA 500 series security appliances with software before 2.1.19 allows remote authenticated users to execute arbitrary commands via crafted parameters to web forms, aka Bug ID CSCtq65681. The attacker can obtain root privileges. An authenticated attacker can exploit this issue to execute arbitrary commands with root-level privileges on the underlying operating system. This issue is being tracked by Cisco bug ID CSCtq65681. The following devices are affected: Cisco SA520 Cisco SA520W Cisco SA540. An attacker must have valid credentials for an affected device to exploit one vulnerability; exploitation of the other does not require authentication. Both vulnerabilities can be exploited over the network. Cisco has released free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20110720-sa500.shtml Affected Products ================= Vulnerable Products +------------------ These vulnerabilities affect the following devices running a software version prior to the first fixed release documented in the Software Versions and Fixes section of this advisory: * Cisco SA520 * Cisco SA520W * Cisco SA540 There are multiple methods to determine the version of system software that is running on a device. At the device web login screen, the system software version is displayed under the "Security Appliance Configuration Utility" heading. Administrators can also log in to a device through the web management interface and navigate to Administration > Firmware & Configuration > Network. The Primary Firmware field appears below Status Information. The number directly beside the Primary Firmware field is the system software version. Alternately, after logging in to the device, administrators can click on the About link on top right side of the screen. The system software version will be displayed below the "Security Appliance Configuration Utility" heading. An example of the system firmware version is 2.1.18. Products Confirmed Not Vulnerable +--------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities. This vulnerability is documented in Cisco bug ID CSCtq65681 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-2547 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 * CSCtq65669 - SQL injection vulnerability CVSS Base Score - 5.0 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Partial Integrity Impact - None Availability Impact - None CVSS Temporal Score - 4.1 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCtq65681 - Privilege escalation vulnerability CVSS Base Score - 9.0 Access Vector - Network Access Complexity - Low Authentication - Single Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 7.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the SQL injection vulnerability could allow the retrieval of usernames and passwords. 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 Small Business Support Center or your contracted maintenance provider for assistance. These vulnerabilities have been corrected in software versions 2.1.19 and later. If administrators of SA 500 Series Security Appliances have configured the Check for New Firmware notification under Administration > Firmware & Configuration > Network, a message regarding new firmware that is available on Cisco.com will be displayed at the next log in to the appliance. Note: the SA 500 will not perform an automatic upgrade to version 2.1.19. The upgrade must be performed by an administrator. The latest software for SA 500 Series Security Appliances can be downloaded at: http://www.cisco.com/cisco/software/navigator.html?mdfid=282414017 Workarounds =========== The following mitigations help limit the exposure to these vulnerabilities. * Disable Remote Management Caution: Do not disable remote management if administrators manage devices via the WAN connection. This action will result in a loss of management connectivity to the device. Several features also require remote management to be enabled, including SSL VPN access and the Cisco Quick Virtual Private Network (QVPN) Utility. Remote Management is disabled by default. Administrators can disable this feature by choosing Network Management > Remote Management. Change the setting for this field to Disabled. Disabling remote management limits exposure because the vulnerabilities can then be exploited from the inter-LAN network only. Disabling remote management limits the exposure as the vulnerabilities can then only be exploited from the inter LAN network. * Limit Remote Management Access to Specific IP Addresses If remote management is required, secure the device so that it can be accessed by certain IP addresses only, rather than the default setting of All IP Addresses. After choosing Network Management > Remote Management, an administrator can change the Remote IP Address field to ensure that only devices with specified IP addresses can access the device. 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: 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 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 If the information is not clear, please contact the Cisco Small Business Support Center or your contracted maintenance provider for assistance. Small Business Support Center contacts are as follows. +1 866 606 1866 (toll free from within North America) +1 408 418 1866 (toll call from anywhere in the world) Customers should have their product serial number available.

This can be exploited to manipulate SQL queries by injecting arbitrary SQL code. 2) Certain unspecified input passed to the web management interface is not properly sanitised before being used. This can be exploited to inject and execute arbitrary shell commands. PROVIDED AND/OR DISCOVERED BY: The vendor credits Michal Sajdak, Securitum.
