Technical description
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.
Remediation
Check the references section for vendor advisories and patches from oracle. Update jre to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
