Vendor Confirmed:  Yes  

Description:   Multiple vulnerabilities were reported in Cisco WebEx Training Center. A remote user can conduct cross-site scripting attacks. A remote user can conduct cross-site request forgery attacks. A remote user can obtain sensitive information. A remote user can access sessions.

A remote user can send a specially crafted URL to obtain the registration ID of other users [CVE-2013-6973]. The vendor has assigned bug ID CSCul57121 to this vulnerability.

A remote user can view the session number for trainings that require host approval before the host approves the attacker as an attendee [CVE-2013-6972]. The vendor has assigned bug ID CSCul57126 to this vulnerability.

A remote user can cause the target user to be redirected to an arbitrary URL [CVE-2013-6971]. The vendor has assigned bug ID CSCul57140 to this vulnerability.

A remote user can view registration error messages to determine if the target email address has already been specified by another registered attendee [CVE-2013-6968]. The vendor has assigned bug ID CSCul36003 to this vulnerability.

A remote user can cause the target user to be redirected to an arbitrary URL [CVE-2013-6966]. The vendor has assigned bug ID CSCul36031 to this vulnerability.

The system discloses the training session information URL prior to confirmation. A remote user can attend the audio conference for a training session without having to confirm the email address [CVE-2013-6965]. The vendor has assigned bug ID CSCul36183 to this vulnerability.

The software does not properly filter HTML code from user-supplied input before displaying the input [CVE-2013-6963]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the WebEx Training Center interface and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user. The vendor has assigned bug ID CSCul36207 to this vulnerability.

The system discloses the training session information URL prior to confirmation. A remote user can obtain the training session access code and password and join the audio conference [CVE-2013-6709]. The vendor has assigned bug ID CSCul57111 to this vulnerability.

The web framework does not properly validate user-supplied requests. A remote user can conduct cross-site request forgery (CSRF) attacks to take actions as the target user [CVE-2013-6710]. The vendor has assigned bug ID CSCul25567 to this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the WebEx Training Center interface, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can obtain sensitive information.

A remote user can access sessions.
