Cisco Webex Network Recording Player and Cisco Webex Player Remote Code Execution Vulnerabilities
Description
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.

Cisco Webex Network Recording Player for Windows improperly validates ARF/WRF files, allowing arbitrary code execution via a malicious file.
Vulnerability
A vulnerability exists in Cisco Webex Network Recording Player for Windows and Cisco Webex Player for Windows due to improper validation of Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. Affected versions include those prior to the fixed releases identified in Cisco Security Advisory cisco-sa-20181003-webex-rce [1]. The issue arises when the software parses specially crafted ARF or WRF files.
Exploitation
An attacker can exploit this vulnerability by sending a user a malicious ARF or WRF file via a link or email attachment and persuading the user to open it with the affected software [1]. No additional privileges or authentication are required beyond user interaction to open the file.
Impact
Successful exploitation allows the attacker to execute arbitrary code on the affected system, potentially gaining full control over the target machine. This results in complete compromise of confidentiality, integrity, and availability [1].
Mitigation
Cisco has released free software updates to fix this vulnerability. Users should upgrade to the fixed versions as specified in the advisory [1]. No workarounds are available; updating is the only mitigation.
