X509TrustManager in (1) Java Secure Socket Extension (JSSE) in SDK and JRE 1.4.0 through 1.4.0_01, (2) JSSE before 1.0.3, (3) Java Plug-in SDK and JRE 1.3.0 through 1.4.1, and (4) Java Web Start 1.0 through 1.2 incorrectly calls the isClientTrusted method when determining server trust, which results in improper validation of digital certificate and allows remote attackers to (1) falsely authenticate peers for SSL or (2) incorrectly validate signed JAR files.

Security readout for executives and security teams

This is an old Java trust-validation flaw. Affected Java SSL and signed-JAR components could make the wrong certificate trust decision, letting a remote party appear trusted or causing signed JAR validation to succeed incorrectly. Business risk is highest where legacy Java 1.3/1.4, JSSE, Plug-in, or Web Start still exists. Likely exposure is limited to legacy Java runtimes, applet/plugin deployments, Web Start applications, or embedded systems that still include the affected components. Modern estates should verify old dependencies, bundled JREs, and vendor appliances rather than assume absence. Treat this as a legacy-risk cleanup item with high impact if present. It is not supported by KEV evidence in the bundle, but broken certificate trust can undermine secure communications and code trust in affected Java deployments. Mitigation focus: Inventory systems using affected Java, JSSE, Plug-in, or Web Start versions.; Apply vendor guidance from Sun/Oracle, HP, or affected platform vendors.; Remove or isolate obsolete Java Plug-in and Web Start dependencies where possible..
