Unspecified vulnerability in Java Web Start (JWS) and Java Plug-in with Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier allows untrusted JWS applications to perform network connections to unauthorized hosts via unknown vectors, aka CR 6727079.

Security readout for executives and security teams

This CVE affects old Sun Java Web Start and Java browser plug-in deployments. A malicious or untrusted Java Web Start application could make network connections to hosts it should not be allowed to reach. The sources do not provide CVSS, detailed root cause, or active exploitation evidence. Exposure is most likely on legacy desktops, servers, appliances, or managed workstations still running the listed Java runtimes with Java Web Start or browser plug-in functionality available. Modern environments that removed Java browser plug-ins and retired old JREs are less likely exposed. Treat this as a legacy exposure discovery item, not a confirmed active emergency. It deserves priority where old Java is still present on systems with internal network reach, because the flaw weakens Java sandbox network restrictions. Mitigation focus: Inventory systems for Java versions at or below the listed affected releases.; Retire or upgrade affected JDK, JRE, SDK, and JWS deployments.; Disable Java Web Start and Java browser plug-ins where not required..
