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
Buffer overflow in the Cisco WebEx Recording Format (WRF) player T27 L through SP11 EP26, T27 LB through SP21 EP10, T27 LC before SP25 EP11, T27 LD before SP32 CP2, and T28 L10N before SP1 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted WRF file, aka Bug ID CSCtz72946.

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

Buffer overflow vulnerability in Cisco WebEx Recording Format (WRF) player allows remote code execution or denial of service via a specially crafted malicious WRF file. The overflow occurs during parsing of WRF file content, leading to memory corruption that can be exploited to execute arbitrary code.

MitigationDeploy vendor-provided patches for affected WebEx player versions (T27 SP11 EP26+, T27 LB SP21 EP10+, T27 LC SP25 EP11+, T27 LD SP32 CP2+, T28 L10N SP1+). Until patched, restrict WRF file handling to trusted sources and consider network-level controls blocking untrusted WRF attachments.

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 WebEx Recording Format Player installation
    Check if Cisco WebEx WRF Player is installed on the system. This may be found in program files, or use system inventory tools to detect WebEx client software.
    Affected if WebEx WRF Player software is present on the system
  2. Determine installed WRF Player version
    Locate the version information for the installed WebEx WRF Player. This is typically available through the player About dialog, installed program properties, or version metadata in the executable.
    Affected if Unable to determine the version prevents accurate vulnerability assessment
  3. Compare version against affected ranges
    Match the installed version number against the following vulnerable ranges: 27.11.0 through 27.11.26, 27.21.0 through 27.21.10, 27.25.0 through 27.25.10, 27.32.0 through 27.32.1, or 28.0.0
    Affected if Installed version falls within any of the affected ranges: 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 28.0.0
  4. Assess WRF file handling exposure
    Determine if users can open or preview WRF files within the player. The vulnerability is triggered when parsing specially crafted WRF file content.
    Affected if Users have the ability to open WRF files from untrusted sources in the WebEx player

A system is affected if the installed WebEx WRF Player version falls within any of the vulnerable ranges (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 28.0.0) and users can open WRF files in the player.

Fixed in 27.25.1127.32.228.0.1
Interim mitigation

Deploy vendor-provided patches for affected WebEx player versions (T27 SP11 EP26+, T27 LB SP21 EP10+, T27 LC SP25 EP11+, T27 LD SP32 CP2+, T28 L10N SP1+). Until patched, restrict WRF file handling to trusted sources and consider network-level controls blocking untrusted WRF attachments.

Recommended fix High confidence

Version 27.11.27+ for T27 L; 27.21.11+ for T27 LB; SP25 EP11+ for T27 LC; SP32 CP2+ for T27 LD; SP1+ for T28 L10N

  1. 1. Identify the current installed version of Cisco WebEx Recording Format (WRF) Player
  2. 2. Based on the installed version line (T27 L, T27 LB, T27 LC, T27 LD, or T28 L10N), determine the minimum fixed version needed
  3. 3. For T27 L (versions 27.11.0-27.11.26): Upgrade to version 27.11.27 or later (SP11 EP27 or subsequent)
  4. 4. For T27 LB (versions 27.21.0-27.21.10): Upgrade to version 27.21.11 or later (SP21 EP11 or subsequent)
  5. 5. For T27 LC (versions 27.25.0-27.25.10): Upgrade to SP25 EP11 or later
  6. 6. For T27 LD (versions 27.32.0-27.32.1): Upgrade to SP32 CP2 or later
  7. 7. For T28 L10N (versions before SP1): Upgrade to SP1 or later
  8. 8. Obtain the update from Cisco's official download site or through your Cisco support contract
Caveat Upgrading WebEx client software may require end-user acceptance of new license terms; ensure compatibility with existing meeting infrastructure before deployment
