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 · unedited
Multiple 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 due to insufficient validation of certain elements with a Webex recording stored in either the Advanced Recording Format (ARF) or the Webex Recording Format (WRF). 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 confidence

The vulnerability exists in Cisco Webex Network Recording Player and Cisco Webex Player for Windows due to insufficient validation of certain elements within Webex recording files in ARF or WRF format. An attacker can craft a malicious recording file that, when opened by a user, allows arbitrary code execution with the user's privileges. The attack requires user interaction (opening a file) but succeeds without any other authentication or privileges.

MitigationApply vendor patches from Cisco for the affected Webex Player software; until patches are available, avoid opening untrusted or unexpected ARF/WRF files received via email or links.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check if Cisco Webex Player is installed
    Open Control Panel > Programs and Features, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' in PowerShell to list installed programs. Look for 'Cisco Webex Network Recording Player' or 'Cisco Webex Player' entries.
    Affected if The software is not listed as installed - not affected. If listed, proceed to version check.
  2. Identify the installed version of Cisco Webex Player
    If installed, note the exact version displayed in Programs and Features, or right-click the player executable in its installation directory (commonly in C:\Program Files\Cisco Systems\Webex\ or similar) and select Properties > Details to view the File Version.
    Affected if Version is not displayed or cannot be determined - treat as potentially affected and escalate for further investigation.
  3. Compare installed version against affected ranges
    For Cisco Webex Business Suite player: version must be >= 39.5.12 to be patched. For Cisco Webex Meetings Online player: version must be >= 1.3.44. For Cisco Webex Meetings Server player: version must not equal 3.0mr2, 4.0, or t39.3.
    Affected if Installed version is below 39.5.12 (Business Suite), below 1.3.44 (Meetings Online), or exactly 3.0mr2, 4.0, or t39.3 (Meetings Server) - YOU ARE AFFECTED.
  4. Check for handling of ARF/WRF file associations
    Open Windows Registry editor and navigate to HKCR\.arf and HKCR\.wrf to see which application is registered to open these file types. Confirm the handler points to the Cisco Webex player.
    Affected if ARF/WRF files are associated with the vulnerable Cisco Webex Player - the attack surface exists if you open these files.

You are affected if Cisco Webex Network Recording Player or Cisco Webex Player for Windows is installed AND its version falls within the affected ranges (below 39.5.12 for Business Suite, below 1.3.44 for Meetings Online, or exactly 3.0mr2/4.0/t39.3 for Meetings Server).
