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 the SendLogAction method in the UUPlayer ActiveX control 6.0.0.1 in UUSee 2010 6.11.0609.2 might allow remote attackers to execute arbitrary code via a long argument.

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 in the SendLogAction method of the UUPlayer ActiveX control (version 6.0.0.1 in UUSee 2010 6.11.0609.2) allows remote attackers to execute arbitrary code by providing an overly long argument, likely overwriting heap metadata to redirect code execution.

MitigationDisable or unregister the vulnerable UUPlayer ActiveX control on affected systems; if a vendor patch is available, apply it; otherwise remove the UUSee 2010 software entirely. Consider network-level controls to block external vectors targeting this ActiveX component.

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. Check if UUPlayer ActiveX control is registered
    Open Windows Registry Editor and navigate to HKLM\SOFTWARE\Classes\CLSID\ or HKCU\SOFTWARE\Classes\CLSID\, search for CLSIDs containing 'UUPlayer' or '{6A0E}xxx' patterns typically associated with this ActiveX control
    Affected if The UUPlayer ActiveX control CLSID is found in the registry, indicating the vulnerable component is registered on the system
  2. Verify the UUPlayer ActiveX control version
    Locate the UUPlayer DLL file (typically uuplayer.dll or similar in the UUSee installation directory, commonly in Program Files\UUSee or %SystemRoot%\Downloaded Program Files), right-click the file, select Properties, and check the File Version on the Details tab
    Affected if The file version is 6.0.0.1, matching the vulnerable version listed in CVE-2011-2589
  3. Check for UUSee software installation
    Open Control Panel > Programs and Features (or run 'appwiz.cpl'), look for 'UUSee' or 'UUSee 2010' in the installed programs list
    Affected if UUSee 2010 version 6.11.0609.2 or similar is installed, as this bundles the vulnerable UUPlayer ActiveX control
  4. Inspect ActiveX control CLSID in Internet Explorer
    Open Internet Explorer, go to Tools > Manage Add-ons > Enable/Disable Add-ons, look for 'UUPlayer' or 'UUMedia Player' in the list of ActiveX controls and note its CLSID and version if displayed
    Affected if The UUPlayer ActiveX control appears enabled in Internet Explorer with version 6.0.0.1 or unspecified version on UUSee 2010 systems

A system is affected if the UUPlayer ActiveX control (version 6.0.0.1) or UUSee 2010 (version 6.11.0609.2) is installed and the vulnerable ActiveX component is registered on the system.
