TITLE

Cisco Unified Communications Manager In SQL Injection vulnerability

DESCRIPTION

Multiple SQL injection vulnerabilities in xmldirectorylist.jsp in the embedded Apache HTTP Server component in Cisco Unified Communications Manager (aka CUCM, formerly CallManager) 6.x before 6.1(5)su3, 7.x before 7.1(5)su4, 8.0 before 8.0(3a)su2, and 8.5 before 8.5(1)su1 allow remote attackers to execute arbitrary SQL commands via the (1) f, (2) l, or (3) n parameter, aka Bug ID CSCtj42064. The problem is Bug ID CSCtj42064 It is a problem.By a third party (1) f , (2) l Or (3) n Any via parameter SQL The command may be executed. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Call Manager component. The system exposes an Apache webserver which contains a JSP script vulnerable to SQL injection. A remote attacker can abuse this to inject SQL statements to be evaluated by the underlying database. Exploiting this issue could allow an authenticated attacker to compromise the affected device, access or modify data, or exploit latent vulnerabilities in the underlying database. This issue is tracked by Cisco Bug ID CSCtj42064. A workaround exists only for the SIP DoS vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110427-cucm.shtml. Customers who are using Cisco Unified Communications Manager 5.x versions should contact your Cisco support team for assistance in upgrading to a supported version of Cisco Unified Communications Manager. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= Cisco Unified Communications Manager is the call processing component of the Cisco IP Telephony solution that extends enterprise telephony features and functions to packet telephony network devices such as IP phones, media processing devices, VoIP gateways, and multimedia applications. Each vulnerability is triggered by a malformed SIP message that could cause a critical process to fail, resulting in the disruption of voice services. All SIP ports (TCP ports 5060 and 5061 and UDP ports 5060 and 5061) are affected. The first SIP DoS vulnerability is documented in Cisco Bug ID CSCti42904 and has been assigned Common Vulnerabilities and Exposures (CVE) identifier CVE-2011-1604. An authenticated, remote attacker with the ability to intercept a packet to the affected device could specify a different location or filename, which may result in the upload of a malicious file. * The second vulnerability could allow an unauthenticated, remote attacker to modify system configuration; create, modify, and delete users; or modify the configuration of Cisco Unified Communications Manager. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS).

In the case of DoS attacks, the affect Cisco Unified Communications Manager processes will restart, but repeated attacks may result in a sustained DoS condition. 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. When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +------------------------------------------------------------+ | Cisco Unified Communications Manager | Recommended | | Version | Releases | |----------------------------------------+-------------------| | 6.x | 6.1(5)SU3 | |----------------------------------------+-------------------| | 7.x | 7.1(5b)SU4 | |----------------------------------------+-------------------| | 8.0 | 8.0(3a)SU2 | |----------------------------------------+-------------------| | 8.5 | 8.5(1)SU1 | +------------------------------------------------------------+ Note: The 7.1(5b)SU4 release of Cisco Unified Communications Manager is expected to be available by the end of April 2011. Workarounds =========== A workaround exists only for the SIP DoS vulnerabilities. Cisco Unified Communications Manager versions 6.1(4), 7.1(2), and 8.0(1) introduced the ability to disable SIP processing. SIP processing is enabled by default. Customers who do not use SIP processing can use the following instructions to disable SIP processing: * Step 1: Log into the Cisco Unified Communications Manager Administration web interface. * Step 3: Change the "SIP Interoperability Enabled" parameter to False, and click "Save". Note: For a SIP processing change to take effect, the Cisco CallManager Service must be restarted. For information on how to restart the service, refer to the "Restarting the Cisco CallManager Service" section of the document at the following location: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/7_1_2/ccmcfg/b03dpi.html#wp1075124 It is possible to mitigate these vulnerabilities by implementing filtering on screening devices and permitting access to TCP ports 5060 and 5061 and UDP ports 5060 and 5061 only from networks that require SIP access to Cisco Unified Communications Manager servers. Additional mitigations that can be deployed on Cisco devices in the network are available in the companion document "Cisco Applied Mitigation Bulletin: Identifying and Mitigating Exploitation of the Multiple Vulnerabilities in Cisco Unified Communications Manager" which is available at the following location: http://www.cisco.com/warp/public/707/cisco-amb-20110427-cucm.shtml Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities.
