Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 21 and earlier, 6 Update 45 and earlier, and 5.0 Update 45 and earlier, and OpenJDK 7, allows remote attackers to affect integrity via vectors related to JMX. NOTE: the previous information is from the June 2013 CPU. Oracle has not commented on claims from another vendor that this issue is due to an incorrect implementation of "certain class checks" that allows remote attackers to bypass intended class restrictions.

Security readout for executives and security teams

This issue affects older Oracle Java and OpenJDK runtimes. A remote attacker could affect integrity through JMX-related behavior, but the public record does not provide a CVSS score, detailed impact chain, or confirmed exploitation. Exposure is most likely where legacy Java runtimes remain on servers, desktops, application stacks, or distributions that shipped affected Oracle Java or OpenJDK 7 packages. Prioritize remediation if legacy Java is still present, especially on systems handling sensitive business workflows. The age of the CVE makes unmanaged legacy runtime exposure the main business risk. Mitigation focus: Apply Oracle June 2013 CPU guidance or relevant downstream vendor errata.; Upgrade affected Oracle Java SE and OpenJDK packages to vendor-fixed releases.; Retire unsupported Java 5, 6, and 7 runtimes where still present..
