CVE-2019-1925
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 · uneditedMultiple vulnerabilities in Cisco Webex Network Recording Player for Microsoft Windows and Cisco Webex Player for Microsoft Windows could allow an attacker to execute arbitrary code on an affected system. The vulnerabilities exist because the affected software improperly validates Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. 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.

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.
-
Check if Webex player is installedOpen Windows Control Panel > Programs and Features, or run 'Get-ItemProperty' in PowerShell for registry key 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*' to list installed programs. Look for 'Cisco Webex Network Recording Player' or 'Cisco Webex Player' or 'Webex' in the name.Affected if Either application appears in the installed programs list
-
Identify the installed Webex player versionIn Programs and Features, click on the Webex player entry and view the Version field, or right-click the player executable (typically at C:\Program Files\Webex\Webex Player\*.exe or similar path) and select Properties > Details to see the File Version.Affected if The version displayed is lower than 39.5.5 for Business Suite, lower than 1.3.43 for Meetings Online, or exactly 2.8, 3.0, 3.0mr2, or 4.0 for Meetings Server
-
Confirm the affected product lineCross-reference the installed product name (Webex Business Suite, Webex Meetings Online, or Webex Meetings Server) with the version found in step 2 using the affected version ranges provided.Affected if The product is Webex Business Suite with version < 39.5.5, Webex Meetings Online with version < 1.3.43, or Webex Meetings Server version 2.8, 3.0, 3.0mr2, or 4.0
-
Verify the player handles ARF/WRF filesConfirm the installation includes support for Advanced Recording Format (ARF) and Webex Recording Format (WRF) file handlers, which is the default behavior for these players.Affected if The player is configured to open ARF or WRF files (default state) and the version is in the affected range
The environment is affected if Cisco Webex Network Recording Player or Webex Player for Windows is installed with a version matching the affected ranges, as the vulnerability triggers when processing malicious ARF or WRF files.
