Cisco Unified MeetingPlace Application Server contains an authentication bypass vulnerability and Cisco Unified MeetingPlace Web Conferencing Server contains an arbitrary login vulnerability. For both vulnerabilities, successful exploitation could allow an unauthenticated, remote attacker to impersonate a legitimate user and send arbitrary commands to the affected system with the privileges of that user.
Cisco has released software updates that address these vulnerabilities. A workaround is available for the Cisco Unified MeetingPlace Web Conferencing Server Arbitrary Login Vulnerability. This advisory is available at the following link:

The following versions of Cisco Unified MeetingPlace Application Server software are affected by the Cisco Unified MeetingPlace Application Server Authentication Bypass Vulnerability:
Cisco Unified MeetingPlace Application Server Version Affected Prior to 7.0 No 7.0 Yes 7.1 Yes 8.0 Yes 8.5 Yes
Cisco Unified MeetingPlace Application Server is not affected by the Cisco Unified MeetingPlace Web Conferencing Server Arbitrary Login Vulnerability.
The following versions of Cisco Unified MeetingPlace Web Conferencing Server software are affected by the Cisco Unified MeetingPlace Web Conferencing Server Arbitrary Login Vulnerability:
Cisco Unified MeetingPlace Web Conferencing Server Version Affected Prior to 7.0 No 7.0 Yes 7.1 Yes 8.0 Yes 8.5 Yes
Cisco Unified MeetingPlace Web Conferencing Server is affected by this vulnerability only if the Remember Me authentication option is enabled. To determine whether the option is enabled, navigate to Home > Administration > Web Server. If the value of Allow Remember Me under Web Server Customization Values section is set to Yes, then the Remember Me option is enabled and the system is vulnerable.
The Remember Me authentication option is enabled by default.
Cisco Unified MeetingPlace Web Conferencing Server is not affected by the Cisco Unified MeetingPlace Application Server Authentication Bypass Vulnerability.
Note: Cisco Unified MeetingPlace Application Server and Cisco Unified MeetingPlace Web Conferencing Server software versions prior to 7.0 reached end of software maintenance. Customers with devices running versions prior to 7.0 should contact their Cisco support team for assistance in upgrading to a supported version.

Cisco Unified MeetingPlace is an on-premises conferencing solution that allows organizations to host integrated voice, video, and web conferencing. The solution is integrated directly into an organization's private voice/data networks and enterprise applications. Cisco Unified MeetingPlace servers can be deployed so that the server is accessible from the Internet, allowing external parties to participate in meetings.
Cisco Unified MeetingPlace Application Server is the core of the Cisco Unified MeetingPlace solution and provides voice and video services, and general support to other components of the solution. Cisco Unified MeetingPlace Web Conferencing Server is a component of the Cisco Unified MeetingPlace solution that allows users to manage meetings and share applications and presentations.
Cisco Unified MeetingPlace Application Server Authentication Bypass Vulnerability
A vulnerability in the authentication code of the webserver component of Cisco Unified MeetingPlace Application Server could allow an unauthenticated, remote attacker to take over a user session after the user has logged out from the affected system.
The vulnerability is due to the affected system not invalidating a user's session when the user logs out. An attacker could exploit this vulnerability by crafting an HTTP GET or POST request and sending it to the affected system. To succeed, the attacker must know the session cookie value from a user that has previously logged out. The Cisco Unified MeetingPlace Application Server will automatically invalidate the session cookie after 30 minutes; therefore the attacker has 30 minutes to perform attack. An exploit could allow the attacker to impersonate a legitimate user and compromise the confidentiality, integrity and availability of the affected system with the privileges of that user.
This vulnerability is documented in Cisco bug ID CSCuc64885 (registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2013-1168.
Cisco Unified MeetingPlace Web Conferencing Server Arbitrary Login Vulnerability
A vulnerability in the authentication code of the Cisco Unified MeetingPlace Web Conferencing Server could allow an unauthenticated, remote attacker to impersonate a legitimate user and issue arbitrary commands to the affected system.
The vulnerability is due to insufficient verification of the user cookies when the Remember Me option is configured on the affected system. An attacker could exploit this vulnerability by crafting a login request and send it to the affected system. The attacker must know a valid user name to execute the attack. An exploit could allow the attacker to impersonate a legitimate user and compromise the confidentiality, integrity and availability of the affected system with the privileges of that user.
Note: this vulnerability affects only Cisco Unified MeetingPlace Web Conferencing servers that are configured with the Remember Me option. Microsoft Outlook Integration is using the Cisco Unified MeetingPlace Application Server for authentication services, and it is not affected by this vulnerability.
This vulnerability is documented in Cisco bug ID CSCuc64846 (registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2013-1169.
