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 buffer overflows in the Cisco WebEx Recording Format (WRF) and Advanced Recording Format (ARF) Players T27LB before SP21 EP3 and T27LC before SP22 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted (1) .wrf or (2) .arf file, related to atas32.dll, a different vulnerability than CVE-2010-3042, CVE-2010-3043, and CVE-2010-3044.

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

Multiple buffer overflow vulnerabilities exist in the atas32.dll library used by Cisco WebEx WRF and ARF Players (T27LB before SP21 EP3 and T27LC before SP22). Attackers can exploit these by tricking users into opening specially crafted .wrf or .arf files, potentially leading to arbitrary code execution or denial of service.

MitigationApply vendor-supplied patches (T27LB SP21 EP3 or later, T27LC SP22 or later) and exercise caution when opening recording files from untrusted sources.

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 WRF or ARF Player is installed
    Check for the presence of Cisco WebEx player software in Program Files (e.g., C:\Program Files\WebEx\WebEx Recording Format Player or similar paths), or look in Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for WebEx entries
    Affected if No WebEx player software is found, then the system is not affected by this specific vulnerability
  2. Locate the atas32.dll library
    Search for atas32.dll in the WebEx player installation directory (commonly C:\Program Files\WebEx\ or subdirectories). Use command: dir /s C:\ProgramFiles\atas32.dll or review the application's installation folder
    Affected if The atas32.dll file does not exist, the vulnerable library is not present
  3. Determine atas32.dll version
    Right-click atas32.dll, select Properties, then look at the Version tab to find the File Version. Alternatively, use a tool like sigcheck or PowerShell: (Get-Item 'C:\Path\to\atas32.dll').VersionInfo
    Affected if The file version matches 26.49, 27.10, 27.11.0.3328, 27.12, or 27.13, indicating a vulnerable version
  4. Determine WebEx player version
    Open the installed WebEx Recording Format Player or ARF Player, go to Help > About, or check the registry under HKLM\SOFTWARE\WebEx for version entries
    Affected if The player version is T27LB before SP21 EP3, or T27LC before SP22, or matches versions 26.49, 27.10, 27.11.0.3328, 27.12, or 27.13

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

Apply vendor-supplied patches (T27LB SP21 EP3 or later, T27LC SP22 or later) and exercise caution when opening recording files from untrusted sources.

Recommended fix High confidence

T27LB SP21 EP3 or later / T27LC SP22 or later

  1. 1. Identify the exact Cisco WebEx Player version installed (T27LB or T27LC build)
  2. 2. For T27LB users: Obtain and apply Service Pack 21 EP3 (SP21 EP3) or later from Cisco
  3. 3. For T27LC users: Obtain and apply Service Pack 22 (SP22) or later from Cisco
  4. 4. Verify the patch was applied successfully by checking the player version
  5. 5. Restart any running WebEx player instances
  6. 6. Test with a legitimate WRF/ARF file to confirm functionality
Caveat Patching may require administrative privileges; test in non-production environment first
