Cross-zone scripting vulnerability in the HandleAction method in a certain ActiveX control in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.5, and RealPlayer Enterprise 2.1.2 allows remote attackers to inject arbitrary web script or HTML in the Local Zone by specifying a local file in a NavigateToURL action, as demonstrated by a local skin file.

Security readout for executives and security teams

This is a legacy RealPlayer browser-control issue. A malicious web page could abuse an affected ActiveX control to place script or HTML into the browser’s Local Zone, weakening normal web security boundaries. Business risk is mainly for older Windows environments that still allow RealPlayer ActiveX components. Exposure is likely limited to legacy Windows endpoints with RealPlayer 11.0-11.1, RealPlayer SP 1.0-1.1.5, or RealPlayer Enterprise 2.1.2 and browser ActiveX enabled. Treat this as a targeted legacy-risk cleanup item. It is not KEV-listed in the provided bundle, but affected ActiveX environments can create meaningful browser security exposure. Mitigation focus: Review RealNetworks advisory for the vendor-approved update or mitigation path.; Remove affected RealPlayer versions where there is no business requirement.; Disable or restrict legacy ActiveX browser use where operationally feasible..
