Descriptions

Multiple vulnerabilities in Cisco Webex Network Recording Player for Windows and Cisco Webex Player for Windows could allow an attacker to execute arbitrary code on an affected system. The vulnerabilities are due to insufficient validation of certain elements of a Webex recording that is stored in the Advanced Recording Format (ARF) or Webex Recording Format (WRF). An attacker could exploit these vulnerabilities by sending a user a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file with the affected software on the local system. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the targeted user.

Múltiples vulnerabilidades en Cisco Webex Network Recording Player para Windows y Cisco Webex Player para Windows, podrían permitir a un atacante ejecutar código arbitrario en un sistema afectado. Las vulnerabilidades son debido a una comprobación insuficiente de determinados elementos de una grabación de Webex que es almacenada en Advanced Recording Format (ARF) o Webex Recording Format (WRF). Un atacante podría explotar estas vulnerabilidades al enviar a un usuario un archivo ARF o WRF malicioso por medio de un enlace o archivo adjunto de correo electrónico y persuadiendo al usuario a abrir el archivo con el software afectado en el sistema local. Una explotación con éxito podría permitir al atacante ejecutar código arbitrario en el sistema afectado con los privilegios del usuario apuntado

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Cisco WebEx Network Recording Player. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of ARF files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
