A vulnerability in Cisco WebEx Meetings Server could allow an unauthenticated, remote attacker to collect customer files via an out-of-band XML External Entity (XXE) injection. An attacker could exploit this vulnerability to gain information to conduct additional reconnaissance attacks. The vulnerability is due to the ability of an attacker to perform an out-of-band XXE injection on the system, which could allow an attacker to capture customer files and redirect them to another destination address. An exploit could allow the attacker to discover sensitive customer data. Cisco Bug IDs: CSCvg36996.

A vulnerability in Cisco WebEx Meetings Server could allow an authenticated, remote attacker to access the remote support account even after it has been disabled via the web application. The vulnerability is due to a design flaw in Cisco WebEx Meetings Server, which would not disable access to specifically configured user accounts, even after access had been disabled in the web application. An attacker could exploit this vulnerability by connecting to the remote support account, even after it had been disabled at the web application level. An exploit could allow the attacker to modify server configuration and gain access to customer data. Cisco Bug IDs: CSCvg46741.

A Buffer Overflow vulnerability in Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) files could allow a local attacker to execute arbitrary code on the system of a user. The attacker could exploit this vulnerability by sending the user a link or email attachment with a malicious ARF file and persuading the user to follow the link or launch the file. Successful exploitation could allow the attacker to execute arbitrary code on the user's system. This vulnerability affects Cisco WebEx Business Suite meeting sites, Cisco WebEx Meetings sites, Cisco WebEx Meetings Server, and Cisco WebEx ARF players. Cisco Bug IDs: CSCvg78835, CSCvg78837, CSCvg78839.

A vulnerability in Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) files could allow a remote attacker to execute arbitrary code on the system of a targeted user. The attacker could exploit this vulnerability by sending the user a link or email attachment with a malicious ARF file and persuading the user to follow the link or launch the file. Successful exploitation could allow the attacker to execute arbitrary code on the user's system. This vulnerability affects Cisco WebEx Business Suite meeting sites, Cisco WebEx Meetings sites, Cisco WebEx Meetings Server, and Cisco WebEx ARF players. Cisco Bug IDs: CSCvg78853, CSCvg78856, CSCvg78857.

A "Cisco WebEx Network Recording Player Remote Code Execution Vulnerability" exists in Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) and WebEx Recording Format (WRF) files. A remote attacker could exploit this by providing a user with a malicious ARF or WRF file via email or URL and convincing the user to launch the file. Exploitation of this could cause an affected player to crash and, in some cases, could allow arbitrary code execution on the system of a targeted user. Cisco Bug IDs: CSCvf49650, CSCvg54853, CSCvg54856, CSCvf49697, CSCvg54861, CSCvf49707, CSCvg54867.

A vulnerability in Cisco WebEx Meeting Server could allow an unauthenticated, remote attacker to modify the welcome message of a meeting on an affected system. The vulnerability is due to insufficient security settings on meetings. An attacker could exploit this vulnerability by modifying the welcome message to a meeting. A successful exploit could allow the attacker to modify the welcome message of any known meeting. Cisco Bug IDs: CSCvf68695.

A "Cisco WebEx Network Recording Player Denial of Service Vulnerability" exists in Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) and WebEx Recording Format (WRF) files. A remote attacker could exploit this by providing a user with a malicious ARF or WRF file via email or URL and convincing the user to launch the file. Exploitation of this could cause an affected player to crash and, in some cases, could allow arbitrary code execution on the system of a targeted user. Cisco Bug IDs: CSCve11545, CSCve02843, CSCve11548.

A Buffer Overflow vulnerability in Cisco WebEx Network Recording Player for Advanced Recording Format (.arf) files could allow an attacker to execute arbitrary code on a system. An attacker could exploit this vulnerability by providing a user with a malicious .arf file via email or URL and convincing the user to launch the file. Exploitation of this vulnerability could allow arbitrary code execution on the system of the targeted user. This vulnerability affects Cisco WebEx Business Suite meeting sites, Cisco WebEx Meetings sites, Cisco WebEx Meetings Server, and Cisco WebEx ARF players. Cisco Bug IDs: CSCve10729, CSCve10771, CSCve10779, CSCve11521, CSCve11543.
