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 Cisco WebEx Recording Format Player is installedOn Windows, check for the presence of 'atgcfgre.dll' or 'WebEx' related DLLs in the system, or look for WebEx recording player entry in Add/Remove Programs. On Mac, check /Applications for WebEx related applications.Affected if The WebEx Recording Format Player software is present on the system
-
Locate the installed WRF player versionOpen the Windows Registry under HKLM\SOFTWARE\Cisco Systems, Inc.\WebEx Recording Format Player, or check the version property of the main player executable file.Affected if Unable to determine the version from registry or file properties
-
Compare your version against affected rangesVersion must fall into one of these ranges to be vulnerable: 27.11.0-27.11.26, 27.21.0-27.21.10, 27.25.0-27.25.10, 27.32.0-27.32.1, or 28.0.0Affected if Installed version matches any of the listed affected version ranges
User is affected if Cisco WebEx Recording Format Player is installed and its version falls within any of the five vulnerable version ranges specified in the CVE.
