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
Huawei CloudUSM-EUA V600R006C10;V600R019C00 have an information leak vulnerability. Due to improper configuration, the attacker may cause information leak by successful exploitation.

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

Huawei CloudUSM-EUA versions V600R006C10 and V600R019C00 contain an information leak vulnerability caused by improper configuration. Successful exploitation allows an attacker to gain unauthorized access to sensitive information stored or processed by the system. The CVSS 7.5 indicates network-exploitable with low attack complexity and no authentication required.

MitigationReview and remediate the improper configuration per Huawei security advisories; apply any available patches or updates to the affected versions. If patches are unavailable, implement compensating controls such as network segmentation and strict access controls.

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 Huawei CloudUSM-EUA installation
    Locate the Huawei CloudUSM-EUA appliance or software in your environment. Check system inventory, network scans, or documentation for presence of this product.
    Affected if Huawei CloudUSM-EUA is present in the environment
  2. Determine installed firmware version
    Access the device management interface or system settings. Look for version information typically displayed in About, System Info, or Firmware sections. Use CLI commands such as 'display version' or check firmware file naming if accessible.
    Affected if Version is V600R006C10 or V600R019C00 exactly
  3. Verify configuration exposure settings
    Examine system configuration files or management interface settings related to access controls, user permissions, file sharing, or API access. Look for configurations that may allow unauthorized information access or directory traversal settings.
    Affected if Misconfigured access controls or exposed sensitive configuration settings are found
  4. Check network accessibility
    Determine if the CloudUSM-EUA management interface or API endpoints are exposed to untrusted networks. Review firewall rules, NAT configurations, and ACLs applied to the device.
    Affected if Service is accessible from untrusted networks without proper authentication barriers
  5. Review audit and access logs
    Examine system logs, access logs, or security event logs for unauthorized access attempts or successful connections from unexpected sources. Check for indicators of information leakage patterns.
    Affected if Logs show unauthorized access or anomalous data access patterns originating from external sources

User is affected if Huawei CloudUSM-EUA firmware version V600R006C10 or V600R019C00 is deployed and the system configuration allows unauthorized access to sensitive information from untrusted networks.
