Descriptions

A vulnerability in the Cisco Webex Network Recording Player for Microsoft Windows and the Cisco Webex Player for Microsoft Windows could allow an attacker to execute arbitrary code on an affected system. The vulnerability exist because the affected software improperly validates Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. An attacker could exploit this vulnerability by sending a user a malicious ARF or WRF file via a link or an email attachment and persuading the user to open the file by using the affected software. A successful exploit could allow the attacker to execute arbitrary code on the affected system.

Una vulnerabilidad en Cisco Webex Network Recording Player para Microsoft Windows y Cisco Webex Player para Microsoft Windows podría permitir que un atacante ejecute código arbitrario en un sistema afectado. La vulnerabilidad existe debido a que el software afectado valida incorrectamente los archivos Advanced Recording Format (ARF) y Webex Recording Format (WRF). Un atacante podría explotar esta vulnerabilidad mediante el envío al usuario de un archivo ARF o WRF mediante un enlace o adjunto de email y persuadiéndolo para que abra el archivo utilizando el software afectado. Una explotación con éxito podría permitir que el atacante ejecute código arbitrario en el sistema afectado.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Cisco WebEx Recorder and 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 processing of WRF files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
