-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Vulnerabilities in Unified Contact Center Express Administration Pages Advisory ID: cisco-sa-20090715-uccx http://www.cisco.com/warp/public/707/cisco-sa-20090715-uccx.shtml Revision 1.0 For Public Release 2009 July 15 1600 UTC (GMT) Summary ======= Cisco Unified Contact Center Express (Cisco Unified CCX) server contains both a directory traversal vulnerability and a script injection vulnerability in the administration pages of the Customer Response Solutions (CRS) and Cisco Unified IP Interactive Voice Response (Cisco Unified IP IVR) products. Exploitation of these vulnerabilities could result in a denial of service condition, information disclosure, or a privilege escalation attack. Cisco has released free software updates that address these two vulnerabilities in the latest version of Cisco Unified CCX software. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090715-uccx.shtml. Affected Products ================= The Cisco Unified Contact Center Express (Cisco Unified CCX) is a single-server, integrated "contact center in a box" for use in deployments with up to 300 agents. Vulnerable Products +------------------ All versions of Cisco Unified CCX server running the following software may be affected by these vulnerabilities, to include: * Cisco Customer Response Solution (CRS) versions 3.x, 4.x, 5.x, 6.x, and 7.x * Cisco Unified IP Interactive Voice Response (Cisco Unified IP IVR) versions 3.x, 4.x, 5.x, 6.x, and 7.x * Cisco Unified CCX 4.x, 5.x, 6.x, and 7.x * Cisco Unified IP Contact Center Express versions 3.x, 5.x, 6.x, and 7.x * Cisco Customer Response Applications versions 3.x * Cisco IP Queue Manager (IP QM) versions 3.x Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= Cisco Unified Contact Center Express (Cisco Unified CCX) servers may be affected by both a directory traversal vulnerability and a script injection vulnerability. The directory traversal vulnerability may allow authenticated users to view, modify, or delete any file on the server through the Customer Response Solutions (CRS) Administration interface. This vulnerability is documented in Cisco Bug ID CSCsw76644 and has been assigned Common Vulnerability and Exposures (CVE) ID CVE-2009-2047. The script injection vulnerability may allow authenticated users to enter JavaScript into the Cisco Unified CCX database. The stored script could be executed in the browser of the next authenticated user. This vulnerability is documented in Cisco Bug ID CSCsw76649 and has been assigned CVE ID CVE-2009-2048. 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. * Incomplete input validation allows modification of OS files/directories (CSCsw76644) 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 - 8.7 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * script injection vulnerability in admin interface pages (CSCsw76649) CVSS Base Score - 5.5 Access Vector - Network Access Complexity - Low Authentication - Single Confidentiality Impact - None Integrity Impact - Partial Availability Impact - Partial CVSS Temporal Score - 4.5 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the directory traversal vulnerability may result in read and write access to files on the underlying operating system. Successful exploitation of the script injection vulnerability may result in the execution of JavaScript of authenticated users and prevent server pages from displaying properly. Software Versions and Fixes =========================== The fixes for these vulnerabilities are included in CRS version 7.0(1)SR2 and are available as a hotfix for customers running versions 5.x and 6.x. The hotfixes are crs5.0.2sr2es09 and crs6.0.1sr1es05.
