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 stack-based buffer overflows in WebGate eDVR Manager allow remote attackers to execute arbitrary code via unspecified vectors to the (1) Connect, (2) ConnectEx, or (3) ConnectEx2 function in the WESPEvent.WESPEventCtrl.1 control; (4) AudioOnlySiteChannel function in the WESPPlayback.WESPPlaybackCtrl.1 control; (5) Connect or (6) ConnectEx function in the WESPPTZ.WESPPTZCtrl.1 control; (7) SiteChannel property in the WESPPlayback.WESPPlaybackCtrl.1 control; (8) SiteName property in the WESPPlayback.WESPPlaybackCtrl.1 control; or (9) OpenDVrSSite function in the WESPPTZ.WESPPTZCtrl.1 control.

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 stack-based buffer overflows in WebGate eDVR Manager's ActiveX controls (WESPEvent.WESPEventCtrl.1, WESPPlayback.WESPPlaybackCtrl.1, WESPPTZ.WESPPTZCtrl.1) allow remote attackers to execute arbitrary code by sending specially crafted input to various functions (Connect, ConnectEx, AudioOnlySiteChannel, OpenDVrSSite) and properties (SiteChannel, SiteName).

MitigationDisable the vulnerable ActiveX controls in Internet Explorer, apply vendor security updates/patches to WebGate eDVR Manager, and implement network filtering to block external connections to untrusted DVR management interfaces.

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 WebGate eDVR Manager installation
    Look for WebGate eDVR Manager in Add/Remove Programs (Windows) or check for installation directories typically under Program Files containing 'WebGate' or 'eDVR' in the folder name
    Affected if The software is installed on the system
  2. Check for vulnerable ActiveX control CLSIDs in registry
    Examine Windows registry under HKCR\CLSID for the following ProgIDs: WESPEvent.WESPEventCtrl.1, WESPPlayback.WESPPlaybackCtrl.1, WESPPTZ.WESPPTZCtrl.1. Use regedit or command 'reg query HKCR\WESPEvent.WESPEventCtrl.1' to check registration
    Affected if Any of these three ActiveX controls are registered on the system
  3. Confirm ActiveX controls are enabled in Internet Explorer
    In Internet Explorer, go to Tools > Internet Options > Security > Custom Level, and check the 'ActiveX controls and plugins' section for settings that allow initialization and scripting of ActiveX controls
    Affected if ActiveX controls are allowed to run in Internet Explorer for the relevant security zone
  4. Identify systems with eDVR management interfaces exposed
    Review network configuration for any exposed DVR management ports or web interfaces associated with WebGate eDVR Manager. Check for listening services on common DVR management ports
    Affected if The eDVR Manager management interface is accessible from network locations

A system is affected if WebGate eDVR Manager is installed with any of the three vulnerable ActiveX controls (WESPEvent, WESPPlayback, WESPPTZ) registered and Internet Explorer is used to access management interfaces.
