Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Java Secure Socket Extension (JSSE) in the Hitachi Cosminexus Developer's Kit for Java in various Hitachi Cosminexus 7.5 products before 07-50-01, when using JSSE for SSL/TLS support, allows remote attackers to cause a denial of service via certain SSL/TLS handshake requests. NOTE: this may be the same as CVE-2007-3698.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The Java Secure Socket Extension (JSSE) in Hitachi Cosminexus Developer's Kit for Java contains a vulnerability where specially crafted SSL/TLS handshake requests can cause a denial of service. This is a vulnerability in the SSL/TLS handshake processing logic within the JSSE component.

MitigationUpdate Hitachi Cosminexus products to version 07-50-01 or later to obtain the patched JSSE component. If immediate patching is not feasible, consider restricting network exposure of affected SSL/TLS services.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed Hitachi Cosminexus product
    Determine which Cosminexus product is installed (Application Server Enterprise, Application Server Standard, Client, Developer Professional, Developer Standard, Operator, Service Architect, or Service Platform). Check product documentation or installed software list for the exact product name.
    Affected if The installed product matches any of the affected Cosminexus products listed in the CVE.
  2. Determine the installed version number
    Locate the version information for the installed Cosminexus product. This is typically found in the product's version details, about dialog, or installation directory metadata. Record the full version string (e.g., 07_50 or 7_50).
    Affected if The installed version is exactly 07_50 or 7_50 (depending on product naming convention).
  3. Verify SSL/TLS services are active
    Determine whether the affected product is configured to accept SSL/TLS connections. This may involve checking running services, listening ports (common SSL ports include 443, 8443, or product-specific ports), or SSL/TLS configuration settings in the product.
    Affected if SSL/TLS services are enabled and accepting connections; the vulnerability manifests during SSL/TLS handshake processing, so exposed SSL/TLS endpoints are required for exploitation.
  4. Compare version against affected range
    Cross-reference the installed version (07_50 or 7_50) against the CVE-affected versions. The CVE indicates version 07_50 (or 7_50) is affected.
    Affected if The installed version matches 07_50 or 7_50 exactly and SSL/TLS services are exposed.

You are affected if you have any Hitachi Cosminexus product from the list at version 07_50 or 7_50 with SSL/TLS services enabled and exposed to network traffic.

Mitigation

Update Hitachi Cosminexus products to version 07-50-01 or later to obtain the patched JSSE component. If immediate patching is not feasible, consider restricting network exposure of affected SSL/TLS services.
