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
Unspecified vulnerability in Hitachi EUR Form Client before 05-10 -/D 2010.11.15 and 05-10-CA (* 2) 2010.11.15; Hitachi EUR Form Service before 05-10 -/D 2010.11.15; and uCosminexus EUR Form Service before 07-60 -/D 2010.11.15 on Windows, before 05-10 -/D 2010.11.15 and 07-50 -/D 2010.11.15 on Linux, and before 07-50 -/C 2010.11.15 on AIX; allows remote attackers to execute arbitrary code via unknown attack vectors.

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

Critical remote code execution vulnerability in Hitachi EUR Form Client and Service products across Windows, Linux, and AIX platforms. The vulnerability is described as 'unspecified' with unknown attack vectors, but CVSS 10 indicates trivial exploitability and complete compromise of the affected system.

MitigationApply vendor patches (05-10-/D 2010.11.15 and later for Client/Service, 07-60-/D for uCosminexus) or implement network segmentation/compensating controls if patches unavailable; verify exposure and disable affected services if possible.

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. Locate Hitachi EUR Form installations
    Search common installation directories for Hitachi EUR Form Client, Service, or uCosminexus EUR Form Service directories on Windows (Program Files), Linux (/opt, /usr/local), or AIX (/usr/opt). Also check for process names related to these products using commands like 'ps aux | grep -i eur' or 'tasklist | findstr -i eur' on Windows.
    Affected if Any Hitachi EUR Form Client, Service, or uCosminexus EUR Form Service installation is found on the system
  2. Identify installed product versions
    Examine version information in installed product directories, check product README files, or run product-specific version inquiry commands if available. Look for version strings matching patterns like 01-00, 01-05, 05-00, 05-10-a, 05-10-b, 05-10-c, 05-10-aa, 07-50, 07-60, or 05-05.
    Affected if The installed version matches or falls within the affected version ranges: Client (01-00, 01-05-/*, 05-00, 05-10-/*, 05-10-a, 05-10-aa, 05-10-b, 05-10-c), Service (01-00, 01-05(*1*), 05-00, 05-10-/*b*), or uCosminexus (07-50, 07-60-/*c*, 05-05, 05-10-/*b*, 07-50-/*c)
  3. Verify if EUR Form services are running
    On Windows, check running services using 'services.msc' or 'sc query' for EUR Form services. On Linux/AIX, check running processes for EUR Form daemons using 'ps aux' or 'lssrc -a' on AIX.
    Affected if Any EUR Form Client, Service, or uCosminexus service is currently running (required for remote exploitation)
  4. Check network exposure
    Review firewall rules and listening ports to determine if EUR Form services are exposed to network access. Use 'netstat -an' or 'ss -tulpn' to identify ports associated with EUR Form services.
    Affected if EUR Form services are listening on network-accessible ports, especially those exposed to untrusted networks

A system is affected if it has any Hitachi EUR Form Client, Service, or uCosminexus EUR Form Service installed with a version matching the affected ranges and the service is running and network-accessible.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor patches (05-10-/D 2010.11.15 and later for Client/Service, 07-60-/D for uCosminexus) or implement network segmentation/compensating controls if patches unavailable; verify exposure and disable affected services if possible.

Recommended fix High confidence

Hitachi EUR Form Client 05-10-/D 2010.11.15 or later; Hitachi EUR Form Service 05-10-/D 2010.11.15 or later; uCosminexus EUR Form Service 07-60-/D (Windows), 05-10-/D (Linux), or 07-50-/C (AIX) 2010.11.15 or later

  1. Identify the specific Hitachi EUR Form product and version currently installed (Client or Service)
  2. Identify the operating system platform (Windows, Linux, or AIX)
  3. Upgrade to Hitachi EUR Form Client version 05-10-/D 2010.11.15 or later (or 05-10-CA version 2010.11.15)
  4. Upgrade to Hitachi EUR Form Service version 05-10-/D 2010.11.15 or later
  5. Upgrade to uCosminexus EUR Form Service version 07-60-/D 2010.11.15 or later for Windows
  6. Upgrade to uCosminexus EUR Form Service version 05-10-/D 2010.11.15 or later for Linux
  7. Upgrade to uCosminexus EUR Form Service version 07-50-/C 2010.11.15 or later for AIX
  8. Verify the upgrade was successful and test that the application functions normally
Caveat As this is a version upgrade from 2010, ensure compatibility with any dependent systems and perform thorough testing in a non-production environment first
