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 OceanStor UDS devices with software before V100R002C01SPC102 might allow remote attackers to capture and change patch loading information resulting in the deletion of directory files and compromise of system functions when loading a patch.

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 OceanStor UDS devices running software versions prior to V100R002C01SPC102 contain a vulnerability in the patch loading mechanism that allows unauthenticated remote attackers to intercept and modify patch loading information. This manipulation can cause deletion of arbitrary directory files and lead to compromise of system functions during the patch loading process.

MitigationUpgrade Huawei OceanStor UDS firmware to version V100R002C01SPC102 or later to remediate this vulnerability. If upgrading is not immediately possible, restrict network access to the device's management interface.

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. Check OceanStor UDS firmware version
    Access the device management interface or use the command line interface (CLI) to query the current firmware version. Common commands include 'show version' or checking through the storage system's management GUI under system information.
    Affected if The installed firmware version is earlier than V100R002C01SPC102 (for example, V100R002C01SPC100 or earlier).
  2. Identify patch loading configuration
    Review the device's patch management settings through the management interface. Look for configuration options related to patch loading, installation, or updates.
    Affected if Patch loading functionality is enabled and accessible without additional authentication layers beyond management interface access.
  3. Assess management interface exposure
    Determine if the OceanStor UDS management interface (typically accessed via web GUI or CLI over network) is exposed to untrusted networks. Check network ACLs, firewall rules, and VLAN configurations.
    Affected if The management interface is reachable from untrusted or external networks without proper network segmentation or access controls.

The environment is affected if the installed OceanStor UDS firmware version is below V100R002C01SPC102 and the management interface is network-accessible.

Interim mitigation

Upgrade Huawei OceanStor UDS firmware to version V100R002C01SPC102 or later to remediate this vulnerability. If upgrading is not immediately possible, restrict network access to the device's management interface.

Recommended fix High confidence

V100R002C01SPC102

  1. Back up the current system configuration and data before initiating any firmware upgrade
  2. Access the Huawei support portal (support.huawei.com) or contact Huawei technical support to obtain the V100R002C01SPC102 firmware
  3. Download the V100R002C01SPC102 firmware package for OceanStor UDS
  4. Follow Huawei's standard firmware upgrade procedure: access the device management interface, navigate to system maintenance or firmware upgrade section, and upload the new firmware package
  5. Initiate the firmware upgrade and monitor the process to completion
  6. After upgrade, verify the system is running V100R002C01SPC102 or later by checking the firmware version in the system information
  7. Restore configuration from backup if needed and verify all system functions are operational
