TITLE

Cisco Security Agent of Management Console Vulnerabilities in arbitrary file creation

DESCRIPTION

The Management Console (webagent.exe) in Cisco Security Agent 5.1, 5.2, and 6.0 before 6.0.2.145 allows remote attackers to create arbitrary files and execute arbitrary code via unspecified parameters in a crafted st_upload request. Authentication is not required to exploit this vulnerability. The flaw exists within the webagent.exe component which is handed requests by an Apache instance that listens by default on TCP port 443. When handling an st_upload request the process does not properly validate POST parameters used for a file creation. The contents of this newly created file are controllable via another POST variable. Successful exploits will allow attackers to modify agent policies and system configuration and perform other administrative tasks, resulting in the complete compromise of an affected device. Failed exploit attempts will result in a denial-of-service condition. This issue is tracked by Cisco Bug ID CSCtj51216. Malicious attackers can exploit these to exploit vulnerable systems. Cisco has released free software updates that address this vulnerability. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110216-csa.shtml. Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by this vulnerability. Details ======= Cisco Security Agent provides threat protection for server and desktop computing systems. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerability 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. Software Versions and Fixes =========================== When considering software upgrades, 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. Cisco Security Agent software can be downloaded from the following link: http://tools.cisco.com/support/downloads/go/Redirect.x?mdfid=278065206 Workarounds =========== The following policy can be configured as a workaround to mitigate this vulnerability. Create a New Application Class +----------------------------- Step 1. Specify the name of the application class as 'CSA MC - all applications but not its descendants'. Step 2. Select when created from one of the following executables in the Add Process to application class area and specify @(regpath HKLM\ SOFTWARE\Cisco\CSAMC60\ProductRootDir default=**\CSAMC*)\**\*.exe as the value. Step 3. Ensure that the Only this process option is selected. Step 4. Click Save. Create a priority deny Application Control Rule +---------------------------------------------- Step 1. Name the APCR as CSAMC applications invoking non-CSAMC applications for better readability. Step 2. Enable logging. Step 3. For Current applications in any of the following selected classes select the application class created under "Create a New Application Class." For the But not option, select <none>. Step 4. For New applications in any of the following selected classes select <All Applications>. For the But not option, select the new application class created under "Create a New Application Class." Step 5. Click Save. Obtaining Fixed Software ======================== 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 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) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac@cisco.com Customers should have their product serial number available and be prepared to give the URL of this notice as evidence of entitlement to a free upgrade. Free upgrades for non-contract customers must be requested through the TAC. Refer to http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html for additional TAC contact information, including localized telephone numbers, and instructions and e-mail addresses for use in various languages.
