CVE-2000-1099: Java Runtime Environment in Java Development Kit (JDK) 1.2.2_05 and earlier can allow an untrusted Java cla...

Security readout for executives and security teams

This legacy Java flaw could let untrusted Java code break out of Java’s sandbox and perform unauthorized actions. The source bundle identifies JDK 1.2.2_05 and earlier. Evidence is old and incomplete, with no CVSS score and no KEV listing, so urgency depends on whether these obsolete runtimes still exist in your environment. Exposure is most likely in legacy systems, embedded appliances, old Unix workstations, or archived business applications still using JDK 1.2.2_05 or earlier. Modern standard Java deployments are unlikely to run these versions, but asset inventories often miss bundled runtimes. Treat this as a legacy exposure check, not an internet-wide emergency. If affected Java runtimes are still present, prioritize removal because sandbox escapes undermine a core containment boundary and the software is far beyond normal support expectations. Mitigation focus: Check Sun and HP vendor advisories for original remediation guidance.; Inventory servers, desktops, appliances, and application bundles for JDK 1.2.2_05 or earlier.; Retire or replace affected runtimes where business dependencies allow..
