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
Heap-based buffer overflow in Cisco WebEx Recording Format (WRF) player T27 LD before SP32 EP16, T28 before T28.12, and T29 before T29.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted audio channel in a .wrf file, aka Bug ID CSCuc39458.

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

Heap-based buffer overflow vulnerability in Cisco WebEx WRF player when parsing crafted audio channels in .wrf files. The overflow occurs during audio stream processing, allowing attackers to overwrite heap memory and achieve remote code execution or cause denial of service through memory corruption.

MitigationApply vendor patches (T27 SP32 EP16, T28.12, T29.2 or later). Until patched, restrict opening .wrf files from untrusted sources and consider network-based controls to block malicious WRF files.

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. Verify Cisco WebEx WRF player installation
    Check for WebEx WRF player (wrfplayer.exe) in typical installation directories such as C:\Program Files\WebEx\WebEx Recording Format Player or C:\Program Files\Cisco\WebEx\WebEx Recording Format Player. Also check Add/Remove Programs for WebEx recording format related entries.
    Affected if The player software is present on the system
  2. Determine installed WRF player version
    Right-click wrfplayer.exe, select Properties, then view the Details tab for version information. Alternatively, run 'wrfplayer.exe -version' from command line if supported.
    Affected if Version matches t27ld, t28, or t29 exactly (these are the affected versions)
  3. Check .wrf file association
    Open Windows Explorer, navigate to a .wrf file if present, right-click and select Properties, then Open With > Choose Default Program to see if WebEx WRF player is associated with .wrf files.
    Affected if WRF player is set as the default handler for .wrf files and could be invoked by opening such files
  4. Verify audio channel parsing is enabled
    The vulnerability triggers when parsing audio channels within .wrf files. Check if the player has audio playback capabilities enabled in its settings/preferences.
    Affected if Audio playback feature is enabled in the player settings

A user is affected if Cisco WebEx WRF player version t27ld, t28, or t29 is installed and the player can open .wrf files, allowing the heap overflow to trigger during audio stream processing.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor patches (T27 SP32 EP16, T28.12, T29.2 or later). Until patched, restrict opening .wrf files from untrusted sources and consider network-based controls to block malicious WRF files.

Recommended fix High confidence

T27 LD: SP32 EP16 or later | T28: T28.12 or later | T29: T29.2 or later

  1. 1. Identify the installed Cisco WebEx Recording Format (WRF) Player version by checking the About section in the player or the program's version properties
  2. 2. If running T27 LD version before SP32 EP16, download and install SP32 EP16 or later from Cisco's official download site
  3. 3. If running T28 version before T28.12, download and install T28.12 or later from Cisco's official download site
  4. 4. If running T29 version before T29.2, download and install T29.2 or later from Cisco's official download site
  5. 5. Verify the installation completed successfully by checking the updated version number
  6. 6. Test that .wrf files open correctly in the updated player
