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
There exists an openssl.cnf privilege escalation vulnerability in ZTE Cloud PC client uSmartview. An attacker can execute arbitrary code locally and escalate privileges.

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

This is a local privilege escalation vulnerability in ZTE's uSmartview Cloud PC client. The vulnerability stems from an insecure openssl.cnf configuration that allows an attacker with local access to execute arbitrary code with elevated privileges. The CVSS 7.8 score indicates a local attack vector requiring low privileges but achieving high impact on system integrity.

MitigationOrganizations should update uSmartview to the latest patched version provided by ZTE and review openssl.cnf configuration files for insecure settings that could permit privilege escalation.

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 if ZTE uSmartview Cloud PC client is installed
    Check for the presence of uSmartview or Zxcloud Irai software on the system. Look for installation directories (commonly under C:\Program Files\ZTE or C:\Program Files (x86)\ZTE) or check the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for ZTE entries.
    Affected if The software is present on the system
  2. Determine the installed version of Zxcloud Irai
    Check the version of the installed ZTE software. Right-click the uSmartview executable, select Properties, and view the Details tab for version information. Alternatively, query the Windows registry or check the uninstall entry for the version number.
    Affected if The version is 7.23.20 or higher but lower than 7.25.43 (7.23.20 <= version < 7.25.43)
  3. Locate the openssl.cnf configuration file
    Find the openssl.cnf file used by the uSmartview application. Common locations include the application installation directory, system OpenSSL directories, or the user's AppData folder. Check both the application directory and system OpenSSL paths.
    Affected if The openssl.cnf file exists in or alongside the uSmartview installation directory
  4. Inspect openssl.cnf for insecure privilege escalation settings
    Open the openssl.cnf file in a text editor and examine the configuration for settings that could allow privilege escalation. Look for any custom OpenSSL engine configurations, extension handling, or policy settings that permit loading arbitrary libraries or executing code during certificate processing.
    Affected if The openssl.cnf contains configuration that permits privilege escalation (settings allowing arbitrary code execution or library loading during certificate operations)
  5. Verify service privilege context
    Check if the uSmartview service runs with elevated privileges or under a high-privilege system account. Use Windows Services management console (services.msc) or run 'sc qc uSmartviewService' to examine the service logon account.
    Affected if The uSmartview service runs under a privileged account (such as SYSTEM, LocalSystem, or Administrator) and the openssl.cnf is writable or contains insecure settings

A user is affected if Zxcloud Irai version 7.23.20 through 7.25.42 is installed and the openssl.cnf configuration used by uSmartview contains insecure settings that could be exploited for local privilege escalation.

Upgrade available Upgrade to 7.25.43 or later
Fixed in 7.25.43
Interim mitigation

Organizations should update uSmartview to the latest patched version provided by ZTE and review openssl.cnf configuration files for insecure settings that could permit privilege escalation.

Recommended fix Moderate confidence

Zxcloud Irai version 7.25.43 or later

  1. Check current installed version of Zxcloud Irai (uSmartview) to confirm it is >= 7.23.20 and < 7.25.43
  2. Navigate to the official ZTE support portal at support.zte.com.cn
  3. Locate the Zxcloud Irai or uSmartview download section
  4. Download version 7.25.43 or the latest available version >= 7.25.43
  5. Close any running instances of the Zxcloud Irai client
  6. Install the updated version, ensuring the installation path does not contain untrusted directories
  7. Restart the client and verify the application runs without errors
