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
The CIDAM Protocol on some Huawei Products has multiple input validation vulnerabilities due to insufficient validation of specific messages when the protocol is implemented. An authenticated remote attacker could send a malicious message to a target system. Successful exploit could allow the attacker to tamper with business and make the system abnormal. Affected Huawei Products are: DP300 versions V500R002C00, V500R002C00B010, V500R002C00B011, V500R002C00B012, V500R002C00B013, V500R002C00B014, V500R002C00B017, V500R002C00B018, V500R002C00SPC100, V500R002C00SPC200, V500R002C00SPC300, V500R002C00SPC400, V500R002C00SPC500, V500R002C00SPC600, V500R002C00SPC800, V500R002C00SPC900, V500R002C00SPCa00; RP200 versions V500R002C00SPC200, V600R006C00, V600R006C00SPC200, V600R006C00SPC300, V600R006C00SPC400, V600R006C00SPC500; TE30 versions V100R001C10SPC300, V100R001C10SPC500, V100R001C10SPC600, V100R001C10SPC700B010, V500R002C00SPC200, V500R002C00SPC500, V500R002C00SPC600, V500R002C00SPC700, V500R002C00SPC900, V500R002C00SPCb00, V600R006C00, V600R006C00SPC200, V600R006C00SPC300, V600R006C00SPC400, V600R006C00SPC500; TE40 versions V500R002C00SPC600, V500R002C00SPC700, V500R002C00SPC900, V500R002C00SPCb00, V600R006C00, V600R006C00SPC200, V600R006C00SPC300, V600R006C00SPC400, V600R006C00SPC500; TE50 versions V500R002C00SPC600, V500R002C00SPC700, V500R002C00SPCb00, V600R006C00, V600R006C00SPC200, V600R006C00SPC300, V600R006C00SPC400, V600R006C00SPC500; TE60 versions V100R001C10, V100R001C10B001, V100R001C10B002, V100R001C10B010, V100R001C10B011, V100R001C10B012, V100R001C10B013, V100R001C10B014, V100R001C10B016, V100R001C10B017, V100R001C10B018, V100R001C10B019, V100R001C10SPC400, V100R001C10SPC500, V100R001C10SPC600, V100R001C10SPC700, V100R001C10SPC800B011, V100R001C10SPC900, V500R002C00, V500R002C00B010, V500R002C00B011, V500R002C00SPC100, V500R002C00SPC200, V500R002C00SPC300, V500R002C00SPC600, V500R002C00SPC700, V500R002C00SPC800, V500R002C00SPC900, V500R002C00SPCa00, V500R002C00SPCb00, V500R002C00SPCd00, V500R002C00SPCe00, V600R006C00, V600R006C00SPC100, V600R006C00SPC200, V600R006C00SPC300, V600R006C00SPC400, V600R006C00SPC500; eSpace U1981 version V200R003C20SPC900.

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

CVE-2017-17168 is an input validation vulnerability in the CIDAM Protocol implementation on multiple Huawei video conferencing and communication products (DP300, RP200, TE30-TE60, eSpace U1981). An authenticated remote attacker can send specially crafted malicious messages with insufficient validation, allowing tampering with business operations and causing system abnormality. The CVSS 6.5 indicates network-exploitable vector requiring authentication with moderate attack complexity.

MitigationApply Huawei-supplied firmware patches for affected product versions. If patches are unavailable, restrict network access to the CIDAM Protocol interface and implement additional input validation at network boundaries.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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
    Determine the exact model of the Huawei video conferencing device (DP300, RP200, TE30-TE60, or eSpace U1981) using the device management interface, web console, or physical label
    Affected if The model is not one of these four product families, the vulnerability does not apply
  2. Check the firmware version
    Access the device administration panel or use the command line interface to retrieve the firmware version. For DP300, compare against the list: v500r002c00, v500r002c00b010, v500r002c00b011, v500r002c00b012, v500r002c00b013, v500r002c00b014, v500r002c00b017, v500r002c00b018, v500r002c00spc100, v500r002c00spc200, v500r002c00spc300, v500r002c00spc400
    Affected if The installed firmware version matches one of the listed affected versions for DP300, or for other products (RP200, TE30-TE60, eSpace U1981) if running an unpatched version from the same firmware lineage
  3. Verify CIDAM Protocol is enabled
    Access the device configuration settings and locate the CIDAM Protocol or related protocol/interface settings. Check whether the CIDAM service is active and listening for connections
    Affected if CIDAM Protocol is enabled and operational on the device, creating the attack surface for this vulnerability
  4. Assess network exposure of the management interface
    Determine if the device management interface (which exposes the CIDAM Protocol) is accessible from untrusted networks. Use network scanning or review firewall rules to identify if TCP/UDP ports used by CIDAM are exposed to the internet or untrusted LAN segments
    Affected if The CIDAM Protocol interface is reachable from external networks or untrusted internal segments without proper access controls

The environment is affected if the device is a Huawei DP300, RP200, TE30-TE60, or eSpace U1981 running a firmware version matching the affected list, with CIDAM Protocol enabled and accessible over the network.
