CVE-2019-1924
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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceMultiple vulnerabilities in Cisco Webex players for Windows stem from improper validation of Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. Attackers can craft malicious ARF or WRF files that, when opened by a user, allow arbitrary code execution 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.
-
Identify if Cisco Webex player is installedCheck the system for Webex player components (such as the Webex ARF/WRF player or Webex Recording Editor). Look in installed programs or check for Webex-related processes/services.Affected if If the Webex player for Windows is present on the system
-
Determine the installed Webex player versionAccess the installed version information through the program's about dialog, installed programs list, or version properties. Compare the found version against the affected ranges.Affected if If the installed version is Cisco Webex Business Suite < 39.5.5, Cisco Webex Meetings Online < 1.3.43, or Cisco Webex Meetings Server versions 2.8, 3.0, 3.0mr2, or 4.0
-
Verify ARF/WRF file handling capabilityConfirm the system has the capability to process Webex recording files (ARF or WRF formats). Check if the Webex player or recording viewer is configured to automatically open these file types.Affected if If the player can open or processes ARF/WRF recording files
A user is affected if they have Cisco Webex Business Suite before 39.5.5, Webex Meetings Online before 1.3.43, or Webex Meetings Server versions 2.8, 3.0, 3.0mr2, or 4.0 installed, and they open malicious ARF or WRF files.

From vendor data1.3.4339.5.5
Apply vendor patches when available. Avoid opening untrusted ARF or WRF files received via email or links. Implement email gateway filtering for these attachment types.
