The (1) Upsell.htm, (2) Main.html, and (3) Custsupport.html components in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.5, and RealPlayer Enterprise 2.1.2 and 2.1.3 allow remote attackers to inject code into the RealOneActiveXObject process, and consequently bypass intended Local Machine Zone restrictions and load arbitrary ActiveX controls, via unspecified vectors.

Security readout for executives and security teams

This older RealPlayer issue could let a remote attacker make certain bundled RealPlayer HTML components bypass Windows Local Machine Zone restrictions and load ActiveX controls. That creates business risk mainly on legacy Windows systems where affected RealPlayer versions remain installed or usable through legacy browser paths. Exposure is most plausible on legacy Windows endpoints with affected RealPlayer or RealPlayer Enterprise versions installed, especially where ActiveX and legacy browser components remain enabled. Modern environments without these products are unlikely to be exposed based on the source bundle. Prioritize as a legacy-software cleanup and endpoint hardening item. It is not KEV-listed in the provided data, but the described impact crosses browser trust boundaries and can load ActiveX controls, which warrants timely removal or vendor-guided remediation where affected versions remain. Mitigation focus: Inventory endpoints for the affected RealPlayer and RealPlayer Enterprise versions.; Check RealNetworks security guidance for fixed versions or vendor-recommended actions.; Remove affected legacy RealPlayer software where no business need remains..
