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 Light Directory Access Protocol (LDAP) clients of Huawei TE60 with software V600R006C00, ViewPoint 9030 with software V100R011C02, V100R011C03 have a resource management errors vulnerability. An unauthenticated, remote attacker may make the LDAP server not respond to the client's request by controlling the LDAP server. Due to improper management of LDAP connection resource, a successful exploit may cause the connection resource exhausted of the LDAP client.

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

The LDAP client implementations in Huawei TE60 and ViewPoint 9030 video conferencing devices have improper resource management when handling LDAP server connections. An unauthenticated remote attacker controlling a malicious LDAP server can cause the client to hang or exhaust connection resources by not responding to authentication or query requests, resulting in denial of service.

MitigationRestrict LDAP client connections to trusted/authorized servers via network segmentation and firewall rules; implement connection timeouts and resource limits on the client side; apply vendor patches when available.

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 device model
    Locate the device model identifier in the system information or device label (TE60 or ViewPoint 9030)
    Affected if device is a Huawei TE60 or ViewPoint 9030 video conferencing terminal
  2. Check installed firmware version
    Access the device firmware version through the web management interface, CLI command 'display version', or system information page
    Affected if firmware is v600r006c00 (TE60) or v100r011c02/v100r011c03 (ViewPoint 9030)
  3. Verify LDAP client feature status
    Navigate to the LDAP or authentication settings in the device management interface and confirm whether LDAP client functionality is enabled
    Affected if LDAP client feature is enabled on the device
  4. Check configured LDAP server connections
    Review the LDAP server configuration in the device settings to identify any configured LDAP server addresses or connection profiles
    Affected if one or more LDAP server connections are configured in the device

Device is affected if it is a TE60 (v600r006c00) or ViewPoint 9030 (v100r011c02 or v100r011c03) with LDAP client enabled and at least one LDAP server configured, exposing it to resource exhaustion from a malicious LDAP server.
