The NeffyLauncher 1.0.5 ActiveX control (NeffyLauncher.dll) in CDNetworks Nefficient Download uses weak cryptography for a KeyCode that blocks unauthorized use of the control, which allows remote attackers to bypass this protection mechanism by calculating the required KeyCode. NOTE: this can be used by arbitrary web sites to host exploit code that targets this control.

Security readout for executives and security teams

This is an old browser-plugin weakness in CDNetworks Nefficient Download’s NeffyLauncher 1.0.5 ActiveX control. A malicious website could calculate a required KeyCode and bypass the control’s intended protection. Business urgency depends on whether legacy Windows/Internet Explorer systems still have this ActiveX control installed and usable. Likely limited to legacy endpoints with CDNetworks Nefficient Download NeffyLauncher 1.0.5 installed and ActiveX execution still possible. Modern environments without Internet Explorer-era ActiveX support are less likely exposed. Address during legacy software risk cleanup, with higher priority if ActiveX-capable browsers remain in use. This is not KEV-listed, but public exploit references make unmanaged legacy exposure avoidable risk. Mitigation focus: Inventory endpoints for Nefficient Download and NeffyLauncher.dll.; Remove the vulnerable ActiveX control where it is not required.; Disable or tightly restrict ActiveX on legacy browsers..
