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
Electronic Numbers to URI Mapping (ENUM) module in some Huawei products DP300 V500R002C00, RP200 V600R006C00, TE30 V100R001C10, V500R002C00, V600R006C00, TE40 V500R002C00, V600R006C00, TE50 V500R002C00, V600R006C00, TE60 V100R001C10, V500R002C00, V600R006C00 have a buffer error vulnerability. An unauthenticated, remote attacker has to control the peer device and send specially crafted ENUM packets to the affected products. Due to insufficient verification of some values in the packets, successful exploit may cause buffer error and some services abnormal.

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 · high confidence

Buffer error vulnerability in the ENUM (Electronic Numbers to URI Mapping) module of multiple Huawei video conferencing products. An unauthenticated remote attacker controlling the peer device can send specially crafted ENUM packets with insufficiently validated values, triggering a buffer overflow that causes service abnormalities.

MitigationApply vendor-supplied firmware patches for the affected product versions; if patches are unavailable, implement network segmentation to restrict ENUM traffic to trusted peers only.

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 product model
    Check the device label, web interface, or system information to confirm the model number (Dp300, Rp200, Te30, Te40, Te50, or Te60)
    Affected if The device is one of these six models
  2. Determine the installed firmware version
    Access the device's web interface or CLI and locate the firmware version information (typically in system settings, about, or version display)
    Affected if The firmware version matches or falls within the affected ranges for that model (v100r001c10, v500r002c00, v500r002c00spcb00, or v600r006c00 depending on model)
  3. Verify if ENUM module is enabled
    Check the device configuration for ENUM (Electronic Numbers to URI Mapping) settings - typically found in telephony, SIP, or network configuration menus
    Affected if ENUM functionality is enabled or configured on the device

A device is affected if it is a Huawei Dp300, Rp200, Te30, Te40, Te50, or Te60 running one of the listed firmware versions with the ENUM module enabled and processing traffic from peers.
