An authenticated local attacker can make processing crash by a malicious certificate. The attacker can exploit this vulnerability to cause a denial of service.

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

Heap overflow vulnerability in the PEM module due to insufficient verification of certificates. An authenticated local attacker can exploit this by presenting a malicious certificate, causing a processing crash and resulting in denial of service.

MitigationApply vendor-provided patches/updates for the affected Huawei product versions. Until patches are available, restrict local access to trusted authenticated users only.

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 Huawei product model
    Access the device management interface or use the command 'display device' or 'display version' to identify the exact model number (Dp300, Ips Module, Ngfw Module, Nip6300, Nip6600, Rp200, S12700, or S1700).
    Affected if The product model is one of the affected models listed in the CVE.
  2. Check the installed firmware version
    Run 'display version' or access the device web interface to retrieve the current firmware version number.
    Affected if The firmware version exactly matches one of the affected versions: v500r002c00, v500r001c00, v500r001c30, v600r006c00, v200r007c00, v200r007c01, v200r008c00, v200r009c00, v200r010c00, or v200r006c10.
  3. Verify PEM module is enabled
    Check the device configuration for PEM (Policy Enforcement Module) or certificate processing features using 'display current-configuration | include pem' or 'display pem status' if available.
    Affected if The PEM module or certificate handling functionality is actively configured on the device.
  4. Confirm local authentication is possible
    Verify whether local user accounts exist and can log in by checking 'display local-user' or reviewing access control settings.
    Affected if Local authenticated access is permitted on the device, allowing an attacker to present a malicious certificate.

A user is affected if they are running one of the listed Huawei product models at any of the specific firmware versions AND the PEM module with certificate processing is enabled on their device.
