The web browser plug-in in IcedTea-Web 1.0.x before 1.0.6 and 1.1.x before 1.1.4 allows remote attackers to bypass the Same Origin Policy (SOP) and execute arbitrary script or establish network connections to unintended hosts via an applet whose origin has the same second-level domain, but a different sub-domain than the targeted domain.

Security readout for executives and security teams

CVE-2011-3377 affects the IcedTea-Web browser plug-in. A malicious Java applet could bypass browser same-origin protections between related subdomains, allowing script execution or network connections to hosts the user did not intend to reach. Exposure is most likely on legacy desktops or servers using affected IcedTea-Web browser plug-in versions with Java applet support enabled. Modern environments that removed browser Java plug-ins are less likely exposed. Treat as a legacy exposure cleanup item. Prioritize environments that still support Java applets, especially managed desktops or internal applications relying on old browser plug-ins. Mitigation focus: Upgrade IcedTea-Web to 1.0.6, 1.1.4, or distro-patched packages.; Apply vendor updates from Red Hat, Debian, Ubuntu, or openSUSE where applicable.; Disable or remove the IcedTea-Web browser plug-in if applets are unnecessary..
