The Java Plug-in in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 17 and earlier; 6 Update 12 and earlier; and 1.4.2_19 and earlier does not prevent Javascript that is loaded from the localhost from connecting to other ports on the system, which allows user-assisted attackers to bypass intended access restrictions via LiveConnect, aka CR 6724331. NOTE: this vulnerability can be leveraged with separate cross-site scripting (XSS) vulnerabilities for remote attack vectors.

Security readout for executives and security teams

This is an old Java browser plug-in access-control flaw. A user who loads attacker-influenced content could let JavaScript from localhost reach other local ports through LiveConnect. The business risk is mainly legacy desktops, admin workstations, or embedded management environments that still depend on obsolete Java plug-ins. Exposure is most likely where legacy Java browser plug-ins remain installed or enabled. Modern fleets that removed browser Java are unlikely to be affected. Server-side Java alone is not identified in the supplied description as the exposed surface. Treat this as a legacy technology risk, not a current internet-scale emergency based on the provided evidence. Prioritize it in programs eliminating obsolete browser plug-ins, especially on privileged workstations or environments with sensitive local services. Mitigation focus: Inventory and remove obsolete Java browser plug-ins where not business-critical.; Check vendor advisories for corrected Java packages and apply supported updates.; Prioritize legacy admin desktops and systems accessing sensitive local services..
