CVE-2022-38081
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 · uneditedOpenHarmony-v3.1.2 and prior versions have a permission bypass vulnerability. LAN attackers can bypass the distributed permission control.To take advantage of this weakness, attackers need another vulnerability to obtain system.
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 confidenceOpenHarmony versions v3.1.2 and prior contain a permission bypass vulnerability in the distributed permission control mechanism. LAN-based attackers can exploit this weakness to circumvent permission checks across distributed devices. Successful exploitation requires chaining with another vulnerability to achieve full system compromise.

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 OpenHarmony versionCheck the system version of your OpenHarmony installation to confirm it falls within the affected range (v3.1 through v3.1.2). Use the system's version reporting mechanism or check /etc/version if accessible.Affected if The installed version is between v3.1 and v3.1.2 inclusive
-
Determine if distributed permission control is in useVerify whether the distributed permission control mechanism is enabled or configured in your environment. This feature allows permission propagation across devices on the same network.Affected if Distributed permission control is enabled or configured
-
Assess LAN exposureEvaluate network accessibility of devices running OpenHarmony. Check if the distributed device ecosystem is reachable from untrusted LAN segments or external networks.Affected if Devices are accessible from LAN segments that are not fully trusted or are exposed to untrusted networks
You are affected if your OpenHarmony version is between v3.1 and v3.1.2 and the distributed permission control feature is in use within an accessible network environment.

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 dataUpgrade OpenHarmony to a version beyond v3.1.2 that addresses this permission bypass. Additionally, implement network segmentation to restrict LAN attackers from accessing the distributed device ecosystem.
