CVE-2019-1641
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA 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 email attachment and persuading the user to open the file with the affected software. Successful exploitation could allow the attacker to execute arbitrary code on the affected system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Webex Player is installedCheck for presence of 'Cisco Webex Network Recording Player' or 'Cisco Webex Player' in Windows Programs and Features, or search for executable files such as 'atgpcex.exe' or 'WebexPlayer.exe' in Program Files directoriesAffected if Either Cisco Webex Network Recording Player or Cisco Webex Player for Windows is installed on the system
-
Identify the exact version numberRight-click the installed Webex Player executable, select Properties, then view the Details tab for the Product Version; alternatively, open the player and check Help > AboutAffected if The installed version matches one of the affected versions: 1.3.33, 1.3.39, t32.9, t33.3.5, t33.5.1 (for Webex Meetings Online) or 3.0mr2, t31 (for Webex Meetings Server)
-
Verify the ARF/WRF file handling feature is presentCheck if the player supports opening ARF or WRF file types by attempting to open a test .arf or .wrf file, or check file association registrations for these extensions in the Windows registry under HKCR\.arf and HKCR\.wrfAffected if ARF or WRF file associations exist and the player can process these recording file formats
-
Review recent playback activity for vulnerable file typesSearch the system for recently opened .arf or .wrf files in user directories, or check Windows Event Logs for application events related to Webex Player file operationsAffected if The system has processed ARF or WRF files, indicating active use of the vulnerable file parsing component
The environment is affected if Cisco Webex Network Recording Player or Cisco Webex Player for Windows is installed with a version matching 1.3.33, 1.3.39, t32.9, t33.3.5, t33.5.1, 3.0mr2, or t31, and the system handles ARF or WRF recording files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataAvoid opening untrusted or unexpected ARF/WRF files; apply vendor patches from Cisco when released; consider endpoint detection capabilities for suspicious file handling.
