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 · high confidence

The CIDAM Protocol implementation on affected Huawei products (DP300, RP200, TE30-TE60 video conferencing endpoints, and eSpace U1981) contains multiple input validation vulnerabilities. An authenticated remote attacker can send specially crafted malicious messages that bypass validation checks in the protocol handler, allowing tampering with business operations and causing system abnormal behavior. The vulnerability stems from insufficient validation of specific protocol messages at parse time.

MitigationApply Huawei security patches for the specific product versions. If patches are unavailable, disable the CIDAM Protocol or restrict network access to trusted authenticated users. Network segmentation can limit exposure to remote attackers.

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 Huawei product model
    Determine if your device is one of the following: DP300, RP200, TE30, TE40, TE50, TE60 video conferencing endpoints, or eSpace U1981 unified gateway. Check the device label, management interface, or product documentation.
    Affected if The device is any of these models and the CIDAM Protocol is in use.
  2. Check DP300 firmware version
    Access the device management interface or use the command line to query the firmware version. For DP300, look for version strings matching: v500r002c00, v500r002c00b010, v500r002c00b011, v500r002c00b012, v500r002c00b013, v500r002c00b014, v500r002c00b017, v500r002c00b018, v500r002c00spc100, v500r002c00spc200, v500r002c00spc300, or v500r002c00spc400.
    Affected if The DP300 firmware version exactly matches one of these listed versions.
  3. Verify CIDAM Protocol configuration
    Access the device configuration menus and locate the CIDAM Protocol settings. Check whether the protocol is enabled or actively configured for business operations.
    Affected if The CIDAM Protocol is enabled and configured on the device.
  4. Assess network exposure of the protocol service
    Review firewall rules, access control lists, and network segmentation surrounding the device. Determine if the CIDAM Protocol service port is accessible from untrusted networks or the internet.
    Affected if The CIDAM Protocol service is reachable from untrusted or external networks without proper access controls.

You are affected if you run any of the specified products with the CIDAM Protocol enabled and your device firmware version matches the affected versions listed, particularly for DP300.
