CVE-2020-1842
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 HEGE-560 version 1.0.1.20(SP2); OSCA-550 and OSCA-550A version 1.0.0.71(SP1); and OSCA-550AX and OSCA-550X version 1.0.0.71(SP2) have an insufficient authentication vulnerability. An attacker can access the device physically and perform specific operations to exploit this vulnerability. Successful exploitation may cause the attacker obtain high privilege.
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 confidenceInsufficient authentication vulnerability in Huawei HEGE-560 and OSCA-550 series storage devices. An attacker with physical access to the device can perform specific operations to exploit this flaw and obtain high privileges. The vulnerability stems from inadequate authentication mechanisms for certain administrative functions.

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 modelLocate the physical device or check device inventory/documentation to confirm the model is either Huawei Hege 560 or one of the OSCA-550 series (OSCA-550, OSCA-550a, OSCA-550ax, or OSCA-550x)Affected if The device model matches any of the affected models listed above
-
Check the installed firmware versionAccess the device management interface or use the command line interface (CLI) to retrieve the firmware version. Common methods include logging into the device console or checking the system information page in the web management interfaceAffected if The firmware version matches exactly: Hege 560 at version 1.0.1.20(sp2), OSCA-550 at 1.0.0.71(sp1), OSCA-550a at 1.0.0.71(sp1), OSCA-550ax at 1.0.0.71(sp2), or OSCA-550x at 1.0.0.71(sp2)
-
Verify physical access controlsInspect the physical location of the device to determine if unauthorized individuals could gain physical access to the storage systemAffected if Physical access to the device is not restricted or monitored, allowing potential attackers physical proximity to the device
-
Confirm administrative function exposureReview whether the device administrative ports or functions are accessible from locations where physical security cannot be guaranteedAffected if Administrative functions on the device are reachable by individuals who have physical access to the equipment
You are affected if you own a Huawei Hege-560 or OSCA-550 series device running one of the specific firmware versions listed and the device has any physical access by unauthorized or untrusted individuals.

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 dataRestrict physical access to affected devices and implement physical security controls. Contact Huawei for firmware updates or patches addressing this authentication bypass. Network segmentation can provide additional defense-in-depth.
