CVE-2017-15341
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 · uneditedHuawei AR3200 V200R008C20, V200R008C30, TE40 V600R006C00, TE50 V600R006C00, TE60 V600R006C00 have a denial of service vulnerability. The software decodes X.509 certificate in an improper way. A remote unauthenticated attacker could send a crafted X.509 certificate to the device. Successful exploit could result in a denial of service on the device.
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 confidenceThe vulnerability exists in the X.509 certificate decoding functionality of affected Huawei AR3200 and TelePresence (TE40/TE50/TE60) devices. When processing a maliciously crafted X.509 certificate, the improper decoding causes the device to crash or become unresponsive, resulting in denial of service.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify device modelDetermine if the device is a Huawei AR3200, TE40, TE50, or TE60 by checking the hardware model label or using 'display device manuinfo' or 'display version' commandAffected if Device model is NOT AR3200, TE40, TE50, or TE60 (not affected)
-
Check firmware versionRun 'display version' or 'display firmware version' to obtain the installed firmware version numberAffected if Firmware version is NOT v200r008c20 or v200r008c30 for AR3200, or NOT v600r006c00 for TE40/TE50/TE60 (not affected)
-
Verify X.509 certificate handling is in useCheck if the device is configured to process X.509 certificates by reviewing SSL VPN, IPsec VPN, 802.1X, or certificate-based authentication configurations using 'display current-configuration' or 'display ssl vpn' commandsAffected if X.509 certificate processing is NOT configured or enabled (the vulnerability cannot be triggered)
-
Inspect for crash or unresponsiveness eventsReview system logs, crash logs, or core dump files for events timestamped around certificate import or authentication attempts using 'display logbuffer' or 'display crash-information'Affected if Device has experienced crashes or unresponsiveness specifically when processing X.509 certificates (indicates potential exploitation)
A device is affected only if it is an AR3200 (v200r008c20 or v200r008c30) or TE40/TE50/TE60 (v600r006c00) AND X.509 certificate handling is enabled AND the device has exhibited crashes or became unresponsive during certificate operations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor-supplied firmware updates from Huawei that address the certificate parsing vulnerability. If updates cannot be applied immediately, consider restricting network access to certificate handling interfaces or implementing ingress filtering for certificate-based connections.
