CVE-2020-1864
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 · uneditedSome Huawei products have a security vulnerability due to improper authentication. A remote attacker needs to obtain some information and forge the peer device to send specific packets to the affected device. Due to the improper implementation of the authentication function, attackers can exploit the vulnerability to connect to affected devices and execute a series of commands.Affected product versions include:Secospace AntiDDoS8000 versions V500R001C00,V500R001C20,V500R001C60,V500R005C00.
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 confidenceThis is an authentication bypass vulnerability in Huawei Secospace AntiDDoS8000 devices. A remote attacker who obtains certain information can forge peer device packets to bypass the improperly implemented authentication function, allowing connection to affected devices and command execution.

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 the device modelCheck the device label, web interface header, or CLI output for 'Secospace AntiDDoS8000' or 'AntiDDoS8000' model identificationAffected if The device is a Huawei Secospace AntiDDoS8000 appliance
-
Check firmware versionAccess the device CLI or web interface and navigate to system information or version display to obtain the firmware version numberAffected if The installed version is exactly v500r001c00, v500r001c20, v500r001c60, or v500r005c00
-
Verify management interface exposureReview network configuration to determine if the AntiDDoS management interface (typically ports 8080, 8443, or SSH on management VLAN) is accessible from untrusted networksAffected if Management interface is reachable from outside the trusted network segment
-
Confirm peer device communication is enabledCheck device configuration for peer device communication settings, HA/cluster configuration, or inter-device authentication settingsAffected if Peer device communication or inter-device authentication features are configured and active
A user is affected if they have a Huawei Secospace AntiDDoS8000 running one of the four specified firmware versions with an exposed management interface and peer device communication enabled.

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 Huawei patches for the affected versions (V500R001C00, V500R001C20, V500R001C60, V500R005C00). If patches are unavailable, implement network segmentation and restrict access to the AntiDDoS management interfaces.
