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 is an information leakage vulnerability in FusionCompute 6.5.1, eCNS280_TD V100R005C00 and V100R005C10. Due to the improperly storage of specific information in the log file, the attacker can obtain the information when a user logs in to the device. Successful exploit may cause the information leak.

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

Information leakage vulnerability in Huawei FusionCompute 6.5.1 and eCNS280_TD where sensitive information is improperly stored in log files. An attacker with device login access can read log files to obtain the leaked information.

MitigationReview and sanitize log files to remove sensitive data, implement proper log handling to prevent sensitive information from being written, and restrict access to log files.

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 FusionCompute version
    Access the FusionCompute management interface or use the command 'cvms VERSION' or check the About page in the management portal
    Affected if Version is exactly 6.5.1
  2. Identify the installed eCNS280_TD firmware version
    Access the eCNS280_TD device CLI and run 'display version' or check the firmware version through the management interface
    Affected if Firmware version is v100r005c00 or v100r005c10
  3. Locate and inspect log files for sensitive data
    Navigate to the log directory (typically /var/log/ or a dedicated log path in FusionCompute/eCNS280_TD) and search log files using 'grep -r -i password' or 'grep -r -i token' to find any sensitive keywords
    Affected if Log files contain plaintext passwords, tokens, keys, or other credentials
  4. Check log file permissions and access control
    Run 'ls -la' on log directories and verify file permissions using 'getfacl' if available; determine if unauthorized users can read log files
    Affected if Log files are readable by non-admin users or the permissions are overly permissive

A system is affected if it runs FusionCompute 6.5.1 or eCNS280_TD firmware v100r005c00/v100r005c10 AND contains log files with improperly stored sensitive information accessible to non-privileged users.
