CVE-2012-1337
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 · uneditedBuffer overflow in the Cisco WebEx Recording Format (WRF) player T27 L through SP11 EP26, T27 LB through SP21 EP10, T27 LC before SP25 EP10, and T27 LD before SP32 CP1 allows remote attackers to execute arbitrary code via a crafted WRF file, a different vulnerability than CVE-2012-1335 and CVE-2012-1336.
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 confidenceBuffer overflow vulnerability in Cisco WebEx Recording Format (WRF) player allows remote attackers to execute arbitrary code via specially crafted WRF files. The vulnerability affects multiple version branches (T27 L through SP11 EP26, T27 LB through SP21 EP10, T27 LC before SP25 EP10, T27 LD before SP32 CP1) and is distinct from related CVEs-1335 and CVE-1336.

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.
-
Verify WebEx WRF Player installationOn Windows, open Control Panel > Programs and Features or use 'Get-ItemProperty' in PowerShell for installed programs containing 'WebEx' or 'WRF'. On Mac, check /Applications folder for WebEx-related applications.Affected if Cisco WebEx Recording Format Player is not found in the system, the system is not affected.
-
Locate the installed WRF player versionIn Windows, right-click the WebEx player in Programs and Features, select Properties, and view the Version field. Alternatively, use command: reg query 'HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall' /s /f WebEx or inspect the player executable directly.Affected if Unable to determine the version number, manual verification of the player executable may be required.
-
Compare version against affected rangesMatch your installed version (format 27.xx.x) against: 27.11.0 through 27.11.26, 27.21.0 through 27.21.10, 27.25.0 through 27.25.9, or 27.32.0 through 27.32.0. If the version matches any of these ranges, the installation is vulnerable.Affected if Installed version falls within any of the four affected ranges listed above.
-
Confirm WRF file handling capabilityCheck if the player is configured to automatically open .wrf files or if users have the ability to open WRF files. This can be verified by checking file association settings or recent file access logs for .wrf extensions.Affected if The player is present and capable of processing WRF files, making it exploitable if the version is vulnerable.
A system is affected if Cisco WebEx Recording Format Player is installed with a version number matching any of the four vulnerable ranges (27.11.0-27.11.26, 27.21.0-27.21.10, 27.25.0-27.25.9, or 27.32.0-27.32.0) and the player can open WRF files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data27.25.1027.32.1
Update Cisco WebEx WRF player to patched versions: T27 LC to SP25 EP10 or later, T27 LD to SP32 CP1 or later, and ensure T27 L and T27 LB branches are at their respective patched releases to prevent code execution via malicious WRF files.
